[Q] TPR connecting to wireless N problem - Epic 4G Q&A, Help & Troubleshooting

I recently moved to TPR to try and get better battery life. I had been on CM9. My phone will not connect to my 802.11n router(non 5 ghz frequency). However, it will connect to my 802.11g connection just fine. I had thought it connected to either one previously, but I could be wrong. It has been so long since I first set up my phone that I can't be remember. Is this expected, or did I find a bug? From looking, it seems the Epic should support N, just not the 5ghz version.

It does support n connections and both my Epics show it is connected as N. Did you try resetting your router? Had that problem with an old Netgear...tossed it for a Cisco and all good.

Thanks for the quick reply Kenny. I gave that a shot and no dice. It must be me. I can keep using my G connection. I've got the signal strength boosted a little on that guy anyway.

Do you have the router set to make 300 Mbs connections?

i haven't had time to flash my ASUS router to ddwrt yet. And I've not bothered digging through all of the limited settings yet, but I can take a peek. Not sure what all capabilities it has.

Wifi and modems

Mods please delete my thread in the other forum I posted in the wrong forum.
Is wireless affected by modem type?
I just started using thunderhawk and shadow kernel. Modem is still eo5. I am noticing my wifi signal is not what is used to be when I was on frozen/genocide.
Will a different modem make a difference?

Samsung turned down the radios in Gingerbread to conserve battery. So wifi is lower in signal, gps locks on less satellites (without the fix) but 3G and 4G seem unchanged.

Anyway to turn the wifi signal up?
Not that I know of. I don't think anyone has looked at it.

I have seen reduced wifi and 4G data throughput speeds ever since installing EI22. I don't test 3G. Multiple ROMs and multiple kernels. Seems I can get a bit of a boost in speed if I disable the slowest clock speeds on my device.
Had no such issue with EC05 SRF and Genocide.
That's my experience, anyway.
The OP was asking about wifi signal strength.

I believe they lowered the power consumption on the radios all the way around. But with wifi don't pay attention to signal bars cuz the devs or samsung change the bars between builds. Example you could have 100% signal but only show 1 or 2 bars depending on the decibal levels they have each bar set to. The only thing that is accurate is a wifi signal analyzer that shows you your signal in decibals.

I think a few people noted that they don't have the same range they had on Froyo with their wifi, comparing the same distances from the router.

I would have to disagree I have analyzed my network in db's since eclair with this phone. I have identical db's in the exact same locations just less signal bars. Its all in peoples heads. So don't believe everything you read. I install wifi networks for a living and use this phone as a testing tool cuz its faster and easier than my laptop. Another thing some people don't understand is interference could be the issue of them not getting the same results. If you have 20 wifi signals broadcasting like in apartment it will degrade your signal terribily. I don't have any other wifi signals around me so my signal is constant no interference.

Weak wifi signal at home????

Hello everyone, Im trying to figure out why my wifi signal is almost non-existent when im downstairs in my house. My router is right next to my ps3 and tv so im always downstairs but i always have a weak signal most times or no bars at all. But when im upstairs i have full bars. Any idea on what i can do to improve this?? I have comcast internet and a Belkin N600 dual band N+ router.
I found this and hope it helps. There is a known issue with the Wi-Fi connectivity.

Wifi Tether issues.

I been trying to use the Wifi Tether app from market but lately my download speeds are really slow. Even though my phone is pulling like 10mb my computer only pulls like 1-2mb. And my hacked hot spot doesn't even work even though it's supposed to be hacked. Anyone have similar issues?

Lol. Thanks for replying. What are we to do .

Could possibly be the ROM you're using. Need more information on what you're running. Try flashing another ROM

I honestly believe this is normal behavior. Looks like Sprint had Samsung put a threshold to throttle tethering speeds. I believe that's what caused the whole slow 4g fiasco on previous ICS builds. They didn't properly bake it in. On Gingerbread I would pull 10+ mb while tethering. Now on ICS I barely break 1 Wether it's wifi tether or the the Sprint hotspot. Also after updating my Evo3D to ICS the tethering speeds dropped down too the same as my E4GT. And I actually pay for it on that phone..

That only works for 3g and being that he said his phone is pulling 10mb he's obviously using his 4g connection. Honestly I've done that tweak in the past and my 3g speeds were still crappy. Even worst it broke streaming on certain apps till I reverted back to the Sprint proxy.
Sent from my SPH-D710 using xda app-developers app
Ugh well this is certainly an issue then if what you say is true. I would like to fully exploit the connection of my phone. Does this happen in cm10? I might give paranoid android or cm10 a go but I've heard the 4g speeds on those are just slow period.

@OP
since you haven't disclosed your setup here is an off the wall suggestion...flash fi25 kernel/modem and test speeds again...
from my experience some ICS kernels/modems can affect 3g/4g speeds
Did you try the WiMax tweaks mentioned in the General forum?
I've tried tethering on all the stock (rooted) ROMs and never get much speed when I turn on 4G. I don't think I've ever gotten over 1Mbps. I've tried the hotspot hack and others. 3G is acceptable for most of my (very limited) tethering needs, so I haven't asked for much help.
For my purposes, 4G on a smartphone is a bit silly since reading forums and RSS feeds doesn't take up much bandwidth. But I would like to tether now and again at higher speeds to download larger files and stream video.

Thanks for directing me to that thread. Unfortunately, I'm unable to get my MSL. I installed a terminal emulator and get nothing when I enter getprop ril.MSL. When I put in getprop by itself and scroll through the list, there is no ril.MSL. I've also tried dialing *#RIL#, running an IPC Dump Log, but the View IPC Dump is blank.
I am rooted, btw, on stock FI25 with Agat's recovery.
What am I doing wrong?
EDIT: Okay, first of all, I was able to make the entry changes using shortcut > Activities Nova Launcher > WimaxHiddenMenu > Extensions. Second, I was able to get my MSL by downloading alogcat, going to dialer and entering ##DATA# > Edit > entering random numbers, then filtering alogcat for MSL. Whew! Anyway, still trying to follow all the instructions in that thread.

I tried settings from the http://forum.xda-developers.com/showthread.php?t=1265990&highlight=wimax thread and it didn't seem to make a positive difference. In fact, I'm having a little trouble with stable connections, so I'll have to try a few different things. Anyway, I'm not optimistic about this helping with tethering. My 4G speeds on my smartphone are terrific! My 4g tethering speeds are...3G-ish.

Best other suggestions I can give - make sure nothing else is running and if at all possible keep it plugged in and cool when tethering. I don't use it much but I keep it around as a backup in case the main net access goes out.

Thanks. Should i try water cooling? I don't use it enough to worry, but like piddling with it to get the best performance. If something changes, I'll post about it.
Funny my post got ignored when I tried to give the best feedback based on experience. If you want fast 4g tethering speeds go back to a gingerbread build and you'll be all set. On ICS the kernels are set up to not allow you to go past 1mb while tethering. I guess that was sprints way of cracking down on the free tethering. You get to enjoy it still but at reduced speeds. My Evo3D is also on the same boat after ICS even with a subscription to Sprint hotspot $29.99.. Both phones had great tethering speeds on gingerbread. On that note good luck because you're never going to go above 1mb unless you count the upload speeds.

I don't get what's going on? Are wii talking about tethering with the cord? If so, I've seen some people talking about tethering with their hotspot. So now I'm a bit confused. Are you all using the "Wifi Hotspot Hack" tether?
I don't know what "speed" problems you all are getting. I've been using the Wifi Tether app for quite some time. Most of the time, ROMs don't let you tether 4G using Sprint Hot Spot hack. The hack would only support 3G. So I just use Wifi Tether anyways. I always get good speeds. What's going on?
And I stream Netflix HD on ICS. So I know I'm getting fast speeds. LoL!!

We're talking about using the phone as a hotspot whether it is with the wifi tether app or the hacked hotspot. Apparently after upgrading to ICS from GB I'm getting throttled data speeds when I use my phone as a hotspot. My phone would pull 10 mbps, but when my computer connects to it is throttled to 2mbps max whether I'm using wifi tether app or the hacked hotspot. What's your setup and what speeds are you getting while tethering?

Gnex and 5ghz WiFi

Can anyone confirm the gnex will run on 5ghz WiFi? I'm researching upgrading my router and want to make sure all my devices will run smoothly. A quick google search says yes but on limited channels.
yes...works here with channel 36 at an avm router

Slow WiFi

I purchased the G3 a week ago , hoping for a change from Samsung. The G3 is overall great but since day one had problems with WiFi. At my job it connects to WiFi but the internet wont work and all my other devices connect no problem. At home all my devices fly on Wifi but the G3 buffers and crawls to load videos and data. Im thinking about exchanging for a new G3 but i see alot of people have the same issues. Wondering is it anything i can do for the G3 to better the experience with Wifi
No troubles here
