[Q] Anyone else having severe (wifi) tethering issues. Link to GoogleCode Bug - Samsung Galaxy Nexus

edit: can't post links, too much noob.
go to google code, search for -- Issue 38563: Upgrade to 4.1.2 broke tethering --
My tethering appears to have gone to crap since 4.1.2
There are quite a few variables so I'm not sure where the problem is, on top of that the issue is not 100% consistent.
It appears that when I am not tethered I get a decent ping on my phone (150ms, 95%)
Shortly after initiating a tether my connection goes straight to hell (300-3000ms 50%)
My laptop is often even worse than my phone.
This is usually with a full 5 bars of 'H'.
I'm gathering the ping stats from my phone with terminal emulator.
I'm using a MacBook Air.
I will try to reproduce the issue with my nexus 7 when I have some spare time.
Anyone else experiencing something similiar?

I, like many others have had this problem since 4.1.2, rolled back to 4.1.1 and WiFi tethering worked again. Back to 4.1.2, stopped working again. Installed 4.2 on Gnex yesterday hoping for fix but still no good.
As 4.1.2 is "old hat" now I have started new issue at Google for 4.2 here
code.google.com/p/android/issues/detail?id=39618
Please anybody with same problem go there and add to report.
DO NOT turn it into a *****ing thread like so many here on xda.!!! The item to which luck02 referred for 4.1.2 at code.google.com is just full of twats ranting about their phone suppliers charges for data and crap like that.
code.google.com is to report faults and bugs and by everybody contributing pertinent information maybe Google will look for a fix. Trolling and whinging does nothing but obscure the facts...... please respect this. Just tell them model number, build and describe fault - thanks

Well there is definitely some ranting and twats involved but to my mind that's just part and parcel of being on the internet. Ignore and contribute as you can. Has anyone tried the CM build on the GNEX? Also, has anyone confirmed / denied whether third party wifi tether applications resolve the issue (requires root)?
Actually even more importantly, has anyone isolated where the breakage is actually occurring? I'm assuming it's something in the drivers / networking layer that is screwing up the routing between incoming data and the wifi layer...
I will probably downgrade if nothing else works.

So I got frustrated and rooted / installed clockwork recovery.
Moved to CM 10 and still have the same issue. I'm thinking it's actually a carrier issue for me at this point.
My carrier term expires in January and I'll probably go to a different carrier then.
Will follow up with more information as I have it, I may roll back to an older version of CM to confirm the problem is still occurring.

Definitely not carrier for me, proved by numerous attempts and firmware this weekend. Gnex running 4.1.1 everything works perfectly. Let phone do ota to 4.1.2, broke WiFi tethering and Bluetooth to vehicle completely. Reinstalled 4.1.1 thro Odin and re-partitioned at same time so completely clean install, WiFi tethering and Bluetooth worked perfectly. Continued on complete wipe track by then installing 4.1.2 thro Odin with re-partition (thus removing possibility that incremental upgrade to 4.1.2 was to blame) still no WiFi tethering or Bluetooth.
Did same for 4.2 using Odin still didn't work. Returned to 4.1.1 using Odin, everything worked.
Even made my own Odin package using radio from 4.1.1 (even tho supposedly same as 4.1.2) system and other files from 4.2 - same result, nothing worked.
To eliminate doubt used same sim card in two HTC phones running 4.0.4, both showed correct working and tethering and Bluetooth. Conclusion, not carrier/ supplier related, but surely random hardware/ firmware incompatibility on some examples of Gnex for unfortunate souls such as us
Tried two WiFi tethering apps with exact same result... shows tether as working, greyed out WiFi icon on tab and no go on laptop or desktop....I have spent hours on this to no avail

Have you tried any network diagnostics while not tethered?
I may be getting carrier and 4.1.2 issues. I was running some ping tests while not tethered yesterday. Full 5 bars of 'H+' running CM10 and I was getting horrible signal. More than 50% dropped packets and long ping times.
I'll roll back to an older CM sometime soon and see if there's a difference over the next couple of days.
Thank you,

I'm Noob, I got problem same error on 4.2 and 4.2.1, this issue over half a month.
I have google some website, found have several people like us have this issue and still no idea to fix it...
Mostly couldn't connect to laptop or Mac Book. For me is PlayStation Vita (firmware 2.0 Wifi only)
My PS Vita could deal with my galaxy Nexus on 4.1.2 , but 4.2 is could reach Internet correctly.
I have tried several Wi-Fi Device to connect my Galaxy Nexus,
My PC , My PS3, My PSP, My Uncle Galaxy Nexus 4.1.1 (Samsung image) are working fine.
Only my PS Vita couldn't...
But base on others, have same issue on other device, so I did think this issue may cause by 4.2.
Base on this issue, I have try "wifi-tether" , whatever this download on Google play! or "3.3 pre-2" on their website.
I have it running on Factory 4.2 , 4.2.1 Rooted + Super user, this couldn't work correctly.
Running on KALO 2.0 ROM, this have error on "Clamping MMS"....
No Luck for me.
My GNexus is only one device at the moment, which could let my PS Vita online... I have some PS Vita game need running online.
This force me stay on 4.1.2 and try disable System update notification next minute, for several weeks or month until the solution come...
Or... Anyone could build a patch which could let 4.2 using 4.1.2 Wi-Fi tethering engine?

[Q] Wifi loses connectivity after period of inactivity

Hello,
I've searched around the Epic 4G Touch forums as best I could, but sadly I couldn't find anything that was exactly this problem (although I found some interesting articles about wifi sleep time but they don't seem to apply). I'm experiencing an annoying issue where I can connect Wifi just fine, but if the phone is left for a small period of time (~10 minutes), wifi appears as if it's still connected, however it cannot send/receive data. When this happens, the wifi status says it's "connected", but there is no data connection. The only way to to get the data back is to turn off wifi, wait for 3/4G connection to initialize, then turn Wifi back on to refresh it...then it's fine again until I set the phone down again.
I had this problem on stock EL29, so I rooted and flashed Phantom Blazer ROM (very cool ROM, but I'm still experiencing the same issue). After reading the threads on here about wifi sleep times (apparently they're backwards with ICS roms), I've experimented with every setting, yet I still have the same issue--Wifi is fine as long as I'm using the phone, I set it down, after about 10 minutes pick it back up, says it's still connected, but no data connection.
has anybody experienced this problem with this phone? I'm about to unroot my phone/go back to factory so I can take it in to a Sprint store, the problem is they (trying not to be offensive) don't seem to know very much about this device. I thought I'd ask the pros before I return it, get an iPhone, and have to eat my words about how cool Android is vs. iPhone in front of all my friends. I'm hoping there's a reliable ROM or app that can resolve this vs. having to just replace the device!
Thanks for your help!
I'm not the only one
I'm not the only one with this problem:
edit: I can't post links to androidforums.com or anywhere else, but this same problem is all over the interwebs and nobody has a solution.
I'm sure it's not my router as my ASUS tablet/laptops/girlfriend's iPhone experiences no connectivity problems. I'm thinking this is a hardware problem with some of these devices. I will unroot/reset to factory tonight and let you know what happens.
What channel is your router on? And what type is it A/B/G/N?
This is s known TW ICS bug, most likely kernel related. Almost everyone is having this issue and there is no fix until Samsung decides to repair it. There are quite a few posts similar to this one. If you're using XDA's search function, it's not very good. Try using Google next time and search XDA that way.

Hey guys, thanks for the response. Just before I unrooted/reset to factory I tried one last solution--download an app called "Wifi Fixer". It has resolved a lot of these problems. It's not 100%, but after testing it for a day so far, I've only had to manually refresh the connection once or twice. It's a lot better, even liveable, and I won't be resetting to factory afterall, at least not until Samsung provides an update. So if anyone is having the same problem, try Wifi Fixer, hopefully it gives you a similar level of success...I'm not super happy about having to run another background process all the time, but it doesn't seem to affect battery, and the fix it provides is worth it to me.
Cheers!
Huh - a couple of things. Noticed this problem crept back in FF18 and didn't know why until I went back and checked the wpa_supplicant.conf that I'm using. The line ap_scan=2 was missing; after adding it back in the signal strength is back to full and stable.
I'll bump the thread but it appears the config changes here still hold after all:
http://forum.xda-developers.com/showthread.php?t=1569348
This should also avoid having the WiFi fixer there as you can specify the country in wpa_supplicant.conf manually.
Thanks for looking in to this! A couple questions from a noob like me though:
When you say the problem crept back in FF18 ... what does that mean? Is that something that exists in the "stock" version of the Epic 4G touch from Sprint?
The manual config file tweaks you're describing ... is that something I can perform myself?
Basically I'm wondering if it's "safe" to revert to stock in order to get consistent wifi signal, or if it's something I'm experiencing because of the ROM I'm using.
Thanks!

[Q] Broken Wifi - Hardware Fault? Help!

Hey there everyone, so since i flashed the CM10 nightly from the 24th, wifi has been nearly completely broken for me. You may have seen my posts where i described how my phone barely ever manages to load anything over wifi and when it does, it does so intermittently and at an extremely slow pace. This renders wifi pretty much useless on my phone. Mobile data IS working though.
Now, i first thought it might just be an issue with the nightly i was using, but this issue persisted on the nightlies from the 25th and 26th of this month (which i did full wipes between). So then, since i wanted to stay with Jelly Bean, i decided to try out Tgascoignes AOSP Jelly Bean (another full wipe here), but then this same issue was there as well. Then, i figured i'd try the first Jelly Bean CM10 nightly, since everything was working great on that one, but then this issue with wifi was still there.
So then i thought it must be an issue with Jelly Bean, so i went back to the most trustworthy and stable ROM i have used so far - One Maximus V2.1 with ICS. Then, this issue still persisted.
So, the tl;dr version of this is, wifi isn't working on any ROM for me and i can't seem to do anything to fix it and i really need some help with this. Do you guys think it might be a hardware issue? My router has been working perfectly for other wireless devices in my house. What plan of action would you recommend? Any help will be very very highly appreciated.
Also, the reason that i'm posting this as a new thread is because this isn't the same wifi antenna problem that has been documented a lot in the other thread. My wifi reception doesn't improve or vary depending on where i press on my phone and that's not the issue at all. If this post still doesn't deserve it's own thread then mods, please remove it and i will ask for help elsewhere.
The most complete restore would be to fastboot oem lock and.run the RUU for your device.
If that doesn't fix it, I don't know what will and neither will HTC I suspect, they'll likely replace the motherboard.

Well, i fully restored my phone back to stock and the issue is still persisting . Mobile data is also being really weird now even though i have set the correct APNs.
I also can't update my phone from the 1.29 firmware to the 2.17 base firmware because my carrier (Virgin) hasn't bothered to put any effort towards pushing out an update.
I think i will have to claim the warranty for my phone through Virgin and hope that they don't notice that it has been re-locked as other people have had such luck too.
Does anyone else have any other ideas about this?
I had a similar problem with my sensation after flashing some custom ( & official roms not meant for my region). Try WIFIX, somewhere in the forums. This could be a WiFi radio region code problem

just do it through virgin - in uk its the retailers responsibility to repair, replace or refund it if they can't prove that the fault was caused by you unlocking it etc.. (if before 6 months after purchase)
I don't know how this has happened now but I had a feeling that there was something wrong with the WiFi antenna of my phone, so I squeezed it really tight at the top left corner where the WiFi antenna is located (as seen in the WiFi faults thread) and now all of the issues mentioned above have been fixed . I have no idea if it was just pure luck and coincidence but now my phone is working normally again. If it wasn't a coincidence, then I really hope that this issue doesn't come up again.
I feel very lucky either way right now! No more need to worry about warranty issues and such . Thanks anyway to you guys for replying though, it's good that this forum chips in to help out those that are in need of help!
Dammit i have no idea what is wrong with my phone. Wifi and mobile data were working fine for a day and a half on the stock ROM, so then i decided to re-root and flash some custom ROMs again and this annoying wifi issue is back now :S. Why would this even happen? I am honestly at such a loss with this. Does anyone have any ideas about what's going on?

[Q] WiFi Constant Download

Having a problem with my WiFi, it is constant on the WiFi download arrow. I have checked the usage with data manager and it seems to be OS Services. I updated to Jelly Bean 3 days via Kies. It was fine the first day and since yesterday I have been having this problem as well as my brother who has a S3 who updated OTA. I started diagnosing the problem and it seems to stop if I disconnect every computer in the house. As soon as I connect one of them no matter which one the constant download arrow returns. This is also happening at my school without my computer there. Had the phone since July never had a problem. Any ideas for a fix?
Btw this is a Rogers I747.

Hopefully somebody figures something out. I had a similar issue with ICS, but it was Doubletwist Airsync forcing my wifi setting to always now. Not sure what is going on now. But if it's doing what you say with the computers, maybe it has something to do with WiFi direct or something.
I have even factory reset and it was still doing it before I even loaded anything on to the phone. Is there a way I can completely fresh install the OS?
Any time I look at my wifi (In both ICS and JB) I have an almost constant download arrow, but only on WiFi.
If I turn wifi off my data does not do the same thing. I downloaded a network monitor and found that even over an hour of idle the phone had only downloaded a few kilobytes of info. Like you said, it was for OS services or something OS related.
I just assume it's some kind of ping that the phone has to do so the router doesn't disconnect it? I'm not overly sure how WiFi works. After seeing no significant decrease in battery life I stopped worrying about it.
Its just odd that 3 months + I have had this phone it never happened. Now all of the sudden this is happening to two phones after the a day after the jellybean update.
sorry to bring this up again, but has anyone found the issue or solution?
My GN 10.1 has this same issue.
I'm sure this is a nice battery drainer.

[Q] losing wifi connectivity- full bars but all gray

so, I've read around here on the XDA forum about problems with wifi connectivity where we have full bars for wifi but they are gray and you are not getting out. many describe my situation but I've not seen any real solutions...
my problem is that I can connect to my wifi router without issue but then a random amount of time later, sometimes fairly quickly and sometimes it's hours later, I will pick up the phone and see full bars but they are gray and I'm not getting out. I can try opening a terminal window and pinging the gateway/dns servers and can't even reach the gateway.
things I have tried:
- turned off MAC filtering on the wifi AP
- switched from a 5 GHZ wifi on the AP to 2.4 GHZ net on the AP and vice versa
- manually set the phone wifi preference to one or the other (5 or 2.4)
- battery pull on the phone
- delete network settings for my AP and reconfigure
I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?
I'm not trying to threadjack here, but I just wanted to share my experiences.
I've been have the exact same thing happen to my phone (Nexus maguro). I've tried every JB rom I could find, several different kernels and my wifi eventually always goes grey on me. All network activities stop. I'm back on stock everything right now and it still happens.
It happens on my home wifi as well as work wifi.
I'm about to puttstock ICS on my phone and try that out for a couple days.
Anyway, good luck with your problems, i'm going to follow this thread in hopes you'll get a solution that may help me.
If I do figure anything out i'll post back.

seems that this is a topic that has been posted on a bit over time with no real single culprit or fix. I'll post back if I figure anything out... I know in the Cyanogen thread, I saw info that stated that the MAC address of the phone was changing and I'm going to try and determine if that is happening to mine.
I have the same issue. Sometimes even when i pick up the phone, if i look fast enough i see that the Wi-Fi bars weren't even there! Thats only 1 out of 5 times though. The other time its usually just grey bars. Sometimes it actually will click back and they'll flash to blue and grey 2-3 times and then go solid blue. Then sometimes like you, they'll stay grey. I've tried everything too...reverting to stock, Different kernels, ROMs, routers, static IP, 2.4 or 5ghz, full auto mode. The only fix that makes it a little more reliable, is using Wi-Fi PM Fast. But even that, is not reliable. I'd say its about 50% reliable then, for a huge sacrfice in battery life. For me i've noticed this started to happen with 4.2. Before that i never had a problem. All other devices though no problem. My Nexus 7 is just fine. But the galaxy nexus, no matter what router or where i am, the Wi-Fi is totally unreliable. For me, it happens within 2 minutes that it will disconnect most times. Then 1 in 10 times it'll be fine for 10 hours.
In all honesty, i've given up. Just come to deal with it. Use mobile networks when i'm not needing to download. I can download files and stream music just fine too. If there is traffic going through, it never disconnects. But when its just sitting there without traffic, it disconnects, or, loses connection to google servers i should say.
well that's not good to hear...
I installed stock 4.0.4 a couple days ago and have not had my wifi go grey on me yet.

yeah, I love Cyanogen so not willing to go back to stock... waiting for them to finish 10.1 and I guess I'll see how it behaves then.
Hi all,
Just to say that I have the same problem. I have been upgraded from ICS to 4.2 and nothing had happened but I had to downgrade to 4.1.1 (AOKP Build 4) due to other issues and after that I started notice the WiFi problem.
At first I thought it was when the screen went off, but I has happened with screen on too. I have to turn WiFi off and the back on to connect properly again, very annoying.
As I said I started noticing this after I downgraded, but then again, I had used AOKP 4.1.1 before without this issue. I think that it is time to change my phone :/

I'm on Muzzy 4.2.2 and I'm currently having the same problem. It's not a new problem since I remember having it months ago (disabled my phone's WiFi because I kept missing emails and other notifications - grew tired of dealing with it). I thought it was my router, so I swapped it with a newer one recently, but it carried forward (old router was TRENDnet Draft N and the new one is ASUS RT-N66U).
I would like to know how to properly troubleshoot this problem.
I'm glad I didnt have to create a thread for this. I have been facing this problem quite a lot. I can confirm that WiFi works absolutely fine until 4.1.2, whether it is stock or CM10 (I havent tried the other ROMs yet). I have faced this problem only from 4.2. It still exists on 4.2.2. Happens on all the ROMs I have tried till now including CM10.1 nightly as well as the stock factory image.
When the phone is sleeping, it seems to lose WiFi connectivity and when woken up, the WiFi bars is grey though it is full. If I am very lucky, it will turn blue automatically. Most of the times, I have to switch WiFi off and back on for it to connect properly.
Anyone knows the root cause for this? In case this has been discussed in any other thread?

have you posted this information over in any of the threads where the developers are working such as Cyanogen in an effort to bring this issue to the forefront for more visibility?
I have had those wifi problems with every android version and rom I had on my GNex as far as I can remember.
Sometimes it will be able to reconnect but sometimes I have to disable and re-enable wifi to get it back.
I too thought that it might have been my crappy router as I have had multiple problems with it over the years (some Linksys router).
This is really annoying because it won't receive any e-mails until I randomly decide to have a look at my phone. :/

trust me, I understand your frustration... some days, I can go almost all day without loosing wifi data throughput and other days it won't last 10 minutes without going to gray bars.
unfortunately, no one is sharing any fixes which tells me that no one has a good handle on the problem.
Same issue for me on stock Android 4.2.2. Leave WiFi on overnight and when I wake up its connected to WiFi but gray bars...

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

I have not yet tried a static IP config on the phone but I can easily try that... {edited to add} well, I tried static config and that didn't help at all...
one other tidbit of info, I have a work Blackberry with wifi and it never loses wifi connectivity so this is a problem unique to my Nexus.
I'm running Cyanogen 10.0.0-toro and no, I haven't tried a full wipe and reload yet.
thoughts or suggestions?

same thing happened to me on toroplus sourcery 5.1, after trying everything i could think of and talking to one of the devs, i finally did a fresh download of rom and gapps. wiped cache,wiped dalvik, factory reset, wipe system, deleted android folder off of storage then installed the fresh download of rom and gapps and its been working great for me since. hope this helps.

The update to 4.2.2 drivers have fixed all WiFi issues for me. For the first time since 4.1 I can now use WiFi optimization now. And WiFi is fully reliable.

Can you elaborate on this? I've flashed 5 different modems and still get this problem... it happens to my cell service bars, as well. Would love to know what the cause is.

i just know ever since moving to a 4.2.2 kernel that has the 4.2.2 drivers my wifi has been stable. I know there was a post in the anarkia thread with the ak kernel that had the drivers. but i believe most any 4.2.2 kernel would have them implemented. i do have the newest bootloader and radio too. but i know as soon add i got the 4.2.2 drivers all issues were resolved wifi wise. of course i think if you have a 4.2.2 kennel you'll have them.

I'm looking forward to that update - I've been watching the Cyanogen threads for when I think the 10.1 has matured enough to become my daily driver... good to know you've had positive results!
Temporary solution
me facing same issues , Solution would be to use an app called wifi fixer by zanish-g1 from the play store ...
it worked for me !! :good:

[Q] Is WIFI Tether working?

I haven't been able to get my wifi tether working. I've searched for hours but most of the post aren't very recent. I've tried adjusting the settings to many different combinations as mentioned in three other posts. I'm on baseband MC2, JB 4.1.2 and have tried two roms...Swampmonster 2.2/2.3 and Macks Allstar 5.0, as well as using both my PC and laptop to connect. I've used the TrevE mods that come with both roms as well as a couple of apps from the play store.
The same thing happens with every attempt, I connect to the AP but don't get any connection to the internet...DNS server is not responding.
I've recently changed from big red over to sprint and have had my N2 for about a week now. Is this a Sprint thing or is it just my unfamiliarity with my Note 2?
Any help would be much appreciated. Dexter's on tonight.....
Also tried WolfRom and USB tethering, still no connectivity

It's been working for me, basically. I'm on a stock deoxided MC2 ROM with Perseus kernal. I get an error but I don't know what it is, since the log gives another error about no file existing. The error I had before trying to reinstall WiFi and BusyBox was a routing fix failed error.
I used this at work for at least six hours to connect a tablet and laptop. I figure I'm using around 2GB to 6GB each night.
Unfortunately, you're going to have to keep experimenting. I suggest trying with just the defaults settings. See what happens. If not, try changing Driver reloads or none. Unfortunately, it's just a lot of trial and error.

Thanks. I don't give up easily...I'll get it working if possible. I'm just wondering if Sprint is blocking the tether because I connect right away with no errors but the "DNS Server is not responding".
I see you're from the bay area. I grew up in SF but haven't been back in a long time. I miss the beach...

Sprint should be blocking you unless there is something off on your phone. My issue, I think, has to deal with the BusyBox Linux binary library that got loaded. I'm assuming maybe a phone wipe and reflash may fix it.
Yea, I'm near the wine valley, actually. Although, I prefer to be back in San Diego.
I installed Goodness Noteworthy v1.0.8 ROM and get good wifi tethering of 3G. I haven't tested 4G as I don't get it yet.
I'm just running stock rooted MC2 with updated CSC data (Garwyn's) and the separate TrevE version of the Wifi Tether APK works like a charm. My kids just used it on 3G and LTE all the way down I-95 in Florida. Sometimes it would boot them all off when switching from LTE to 3G, but they'd reconnect without issue.
Not sure if that helps you, other than I'm using the very latest MC2 OTA and maybe you're still using a ROM based on the leak? I'm not a dev, so if I'm talking out of my posterior just disregard!
Got it working
I'm still not sure why I had problems when nobody else did on the respective threads for the roms I mentioned above.
I did get it going though...For the touchwiz roms I had to run ISWAT tether unlocker while my tether was active (It's on the Play Store).
Right now I'm running LiquidSmooth's AOSP rom and the native tether works great. I've been bouncing back and forth between nandroid
backups; I like TW most of the time but when I want to tether or am looking for speed/responsiveness I switch over to AOSP.
Just to make sure, have you tried this: http://forum.xda-developers.com/showthread.php?p=40234725
I flashed it on deodexed stock MC2 and it works great, even with tablets and an iPod Touch.
I got it working with Treve mod
WifiTether_TrevE_Mod_11_20_2012_insmodv3.apk
Had to change one settings, or else it wouldn't appear on PC
Change Device-Profile to Generic ICS/JB wlan0

I've got it working on deoxidized rooted stock rom. I'm using the latest beta from July 20, 2013 (TrevE Mod Wifi Tether. The only setting I needed to change was to Driver Reload 2.
wifi-tethering
Now, I'm also using the Wifi -Tethering . its still working now.
you can find info from rootnote2.com
Is the problem of wifi tether under AOSP rooms on this device totally insoluble?
I've never found an answer to it, only directions to fixing it under TouchWiz or vague changelog entries about having 'fixed wifi tether' on Carbon and such, which did no such thing.
Standard wifi tether app 3.3b2 fails to start an access point. TrevE mod claims to start fine in the app's log, but no access point shows up on a scan. The mobile hotspot function in system settings also starts up, and even let's devices connect, but there's no data transfer.
I understand that there's something bad going on with Samsung's release of wifi drivers, so I'm just hoping that someone somewhere has looked into this.
