Wireless N on my Evo?

Ok I have read that Wireless N was enabled by an OTA and I also read that you need to perform a hack to get it... So now I am confused.. Which one is it and how do I do it if a hack is required?

the Wireless N hack was for Eclair. Froyo does not need the hack.

Thank you so much!

just dont think your are going to see anything close to N speeds though... it cant.
if i recalled and i dont hqve the right app installed to verify, but i think you are limited to a max of something like 65mbps. so that is a farfarfar cry from N and only slightly better than 54G.

I just want better connectivity and faster speeds than what I get now.. I am 1 wall away from my 6yr old wireless g router and my evo struggles to hit 1mbps download speeds and drops to 1 bar.. I hate it! Would be nice to get 4g like speeds on wifi... Like 3-10mbps down.. So I just ordered a dlink wireless n xtreme router.. Hope it works better than what I currently have.

Wireless N on my EVO?
Well, a WiFi connection to your Wireless N router will much exceed 3G and 4G from my experience, you will be happy. BTW: I have a Froyo EVO, just tested it, forced my LinkSys WRT350N to accept WirelessN only, connected with no issue.

My phone is a weapon - It jams Wifi

I was working with a coworker, and he noticed something strange. So we started doing tests and realized that my T989D jams wifi within 20 feet of it.
Heres the test setup
Multiple Wifi Networks:
WorkWifi(Linksys router)
Hotspot created by an iPhone
Devices used for speed tests
macbook pro(his)
MSI GT60(mine)
iPhone(when not acting as hotspot)
We ran speedtest.net tests, which shows average speeds, but ALSO, shows a graph with where speeds fluctuate.
Scenario One - My laptop is tethered via wifi hotspot to my phone
His laptop is on the WorkWifi
He first noticed, that while my laptop was rebooting, his FTP file transfer speeds went from around 30kb to 2mbit/second. When my laptop started, it went back down. Then we started running tests. Side by side speed tests(remember, hes on a different wifi network so its not about lack of bandwidth). Every time my laptop was downloading over the wifi to my phone then to 4g, his speedtest graph showed a DROP, a huge drop, then when it was done, his sped back up.
Second Scenario:
His iPhone tethered via wifi to my phone. His laptop and my laptop doing speed tests on WorkWifi. While his iphone was downloading, both of our laptops saw a HUGE dip(well below what is available on the work Wifi)
Third Scenario:
iPhone, both laptops on Work wifi
My phone on Workwifi, doing speedtest itself with the app.
All other devices slow to a crawl while my phone downloads.
Has anyone else noticed any strange wifi behavior around their phone?

there is an app in android market called "WiFi Kill" that does that intentionally
however in your case, it's rather un-intented, so perhaps some borked ROM with WiFi settings?
try a full wipe and flash a ROM again do another clean wipe before booting into the OS
do not restore any backup, it should not causes any more problem after you join the WiFi at this point

There is also an app called network spoofer.. I don't think it's in the market but it's a free download able apk.. It's basically an app for trolls that messes with people on the same network as you.. My favorite is the YouTube Rick roll.. F***ing hilarious! You'll know what I mean if you try it

I'm gonna say the WiFi tethering is using the same frequencies as the other WiFi networks causing loss of packets in the communication through the air. Happens to me when we use the cordless phones which operate at 2.4GHz.

Change what channel the router is running on.....default is usually 6.....put on 1 or 12

On a side note wireless telephones can cause this (most run on a 2.4 ghz frequency, just like wifi!! ). 6 1 and 11 are common in the US. Try the things inbetween .

1,6 and 11 are popular because they are isolated from one another, all the other ch's overlap. If you put your router on a channel in between you are now getting interference from 2ch's not just one.

He wants USB Tethering. I have noticed that it is actually broken on a LOT of JB ROMs but nobody uses it or bothers to test it so it goes unnoticed. You might wanna try ICS.... I don't use USB Tethering but I have seen the problem across multiple devices on JB (excluding official JB of course)

Oops thats what happens when replying to a post when half asleep. I didn't think people still use usb thethering. Anyway right now best to buy a usb wireless adapter and use the modified wireless tether for root users. Unless someone else knows of a way to usb tether that works on jb.

Yep, go ICS or get a wireless adapter I think are your only choices... The wireless adapters are relatively cheap on Amazon.

USB Tether app
I use pdanet for my USB tethering needs. I am currently on TBGS3 5.0 (GB08) and tested it. It works flawlessly... the only thing is you may have to pay for the full functionality, depending on your needs. The app itself is not on the market, but if you google it you will get to there main cite, where you can download the app for your computer and, utilizing the push to phone function, can install the app on your phone. Good luck, hope this helped. :good:

If you're getting an "account not authorized" message thats the carrier.
Hotel doesn't have wifi, you can't tether from mobile data...
I don't think you have any real options, unless you can get to a Mickey D's or something that offers wifi...

I usb to my laptop because the wireless won't connect to that computer (I've tried everything with no luck) but every other device in the house will, and my phone is the only one with tethering capability. So I hop on wifi and plug and play. Unfortunately my scenario doesn't help your situation

Running into the same issue. Assuming and hoping it is resolved in one of the new updates or a ROM from a dev.
It connects, and would work fine, then if I make a call or something, it would go in this dormant mode.
Dont want to sabotage your thread Abhi, but another issue with Wifi I am dealing with is that even though I have set Network discovery to Off, it would keep finding Wifi Networks to connect to. Got tired of pulling my hair the first couple days, so just turn wifi off when I leave home.

Yes hopefully it will be resolved in the new update and I have never experienced that. You might wanna check your wifi setting.
Sent from my SGH-M919 using xda app-developers app

It seems like the S4 phones sure do have a lot of problems that people "hope" will be resolved with a magical OTA. Maybe it'll happen.
Anyway, I ran across this thread in the AT&T S4 forum, maybe it can help with the issue...if it works at all.
http://forum.xda-developers.com/showthread.php?t=2260449

I spent days researching and trying to figure out how to fix my wifi problems. I found quite a few threads with people reporting wifi problems plaguing the Galaxy SIII as well so I used their solutions to solve my wifi problems with the S4. Here's my solution.

No issues here. Maybe because I'm using 5ghz n?

i was thinking i was the only one as i saw no mention of it;
but yes, my wifi is unusually slow.
my LTE speeds are WAY faster.
my ap is a Ubiquiti Power AP N.
my SIII and Nexus 4 would easily match my ISP max speed... 50 Megabit.
S4 ?
i get around 25, 26, 27 megabits.
hmm.

I'll try that next. It's a lot better than doing *#0011# every reboot.. I had some issues with 4G doing basically the same thing that it was with WIFI, but I lost the connection soon after; so maybe it was a bad area.
---------- Post added at 10:48 PM ---------- Previous post was at 10:37 PM ----------
It doesn't work for me on 5GHz. Sorry, maybe it does. I need to test it more. My XDA app keeps crashing and I need to use a more reliable program to test the connection.
Eh, some of my other devices cannot even see the network; so this isn't a solution for me. I hope they actually fix this or maybe CM doesn't have this problem.

Have a DLink DIR-855. Connects on both 2.4 & 5, but cannot access internet beyond a few seconds. Tried all of the above solutions, but no luck. Funny enough, I have a DLink repeater/booster that I connect to without a hitch!??
S2, S3, GN2 work flawlessly on all connections...

I also have dlink and does this look weird

Rom with best hot spot/wifi tether?

Question, are there any roms out there that have a better quality hot spot /wifi tether than others or is this feature just generally poor on this phone?
The reason I am asking is that my original evo had great hot spot quality. I drive back and forth from Houston to San Antonio and with the evo my wife would be able to be connected and work on her laptop the whole way. With this phone she can't.

No not at all just turn it on. Uses your phone number as password but you can change that. Treves has a lot more settings and configuration. This is the sprint hot spot and you just turn the switch to on.

I completely agree, but I thought it mentioned he was having trouble with it. I haven't used either much, but they both seemed to work equally as well when I did use them. The native hotspot is easier to use too.
