[Q] Connecting to 5Ghz Wireless N - myTouch 4G Q&A, Help & Troubleshooting

Is anyone having trouble connecting to their wireless N router using 5Ghz?
i am using an apple extreme router and when i set it to 5Ghz only and try to connect the phone says its connecting and then goes back to disconnected status. If i reboot the phone it will usually connect, but if i turn wifi off and back on it does not reconnect.
When i set the router to 2.4Ghz only the phone sees and connects to it instantly. Even when i turn wifi on and off.
Just curious if others are having similar issues.

nope, i am not seeing such problem. its working great here for me on my D-link DIR825 router where it connects instantly. though, initially, i had a problem connecting to my 5Ghz band that went away after reducing my channel to 48 (5240 MHz)
I would recommend trying to reduce your channel number and see if that will fix your problem.
Thanks,

I see your problem...you're using an Apple product lol.

LOL!! Some Apple products are good!
Appreciate the replies.

No such problem here. I have a dual band Netgear with separate SSIDs for each band. I connect to my 5ghz band just fine.

I have mine connected to a Airport Extreme as well. Just today I separated the b/g and a bands into separate SSIDs so I could choose the a band from the phone.
So far it seems to be working ok, after reading your post I enabled wifi and it didn't connect so I disabled and reenabled and it worked. Disconnected and reconnected twice after that without trouble. Do you have any remembered b/g networks in the area? Maybe see if forgetting those helps.

Nah, no nearby b/g networks. If I turn wifi on and off when using 5 ghz the phone will connect sometimes. At 2.4 ghz it always connects though. I was out of town last weekend so I am going to try messing with the channels like someone else suggested and see what happens.

Because of the higher frequency, the 5ghz band generally has difficulty traveling through walls and floors. The 2.4 ghz frequency is a lot more reliable in that way but tends to be susceptible to microwave interference and other nearby users running similar bands. The only advantage 5 ghz will give you is less traffic interference. It's not faster and certainly not a stronger signal. Go with 2.4 ghz if you don't have problems with it.

Thanks for the info!

Where is wifi N?????

Videos for the htc desire show it with wifi N and the spec sheets show wifi N. Does anybody know if any G2 tear downs show that it does infact have the hardware to run N? Are the devs working on enabling this?

Yes it does. I have wifi n at home connects just fine.

I have tried wifi n at two differ locations.. my gf doesn't pick it either and neither does my friend's g2. What we doing wrong? Our laptops pick up the band easily.
Sent from my T-Mobile G2 using XDA App
Wifi N can run on either 2.4 GHz or 5 GHz. The G2 only supports 2.4 GHz, but many people run their N routers on 5 GHz to avoid the congestion on 2.4GHz.
You need to go to Menu-Settings-Wireless & Networks -Than Wi-Fi Settings to connect to nearby networks. I noticed when I turned on the wi-fi at first it did not connect right away. You need to view the wireless networks in order to connect. Once you connect it automatically saves. So each time you turn on your wi-fi it connects automatically.

It took me forever to figure this out with my N1. I went through all of the trouble of reconfiguring my router to use N on 2.4GHz, and it didn't make much of a difference anyway. Went back to 2.4GHz for b/g and 5GHz for N (my router has 2 radios).
I actually get a faster/better connection over HSPA+ (up and down) than I get through my router and cable modem.
Most dual band routers running both b/g and n will only allow n to run on the 5ghz band. You can only switch frequencies if your router is running the n band alone.

wifi issues on N4 possible fix?

for those with wifi 'broken' try to change your router settings to WPA2 personal (TKIP+AES) that seems to work for me now,
other settings 'broke' the wifi
this might be just an issue with must me and my router
*spoke too soon: still broken, it only works certain times, mostly it just spins when i try to connecto to online
the wifi icon keeps flashing a black dot... that means the wifi is NOT working right? it should be just a solid blue bars?
on wifi advanced settings, WPS Pin Entry - what is this and do i need to enter that pin on my router?
still no luck with wifi on my network after flashing back to stock 4.2 from 4.2.1
same 'broken' wifi
might be this phone's wifi hardware is incompatible with wDDRT router?
Firmware: DD-WRT v24-sp2 (10/10/09) std
my other wifi devices work perfectly fine, so im really stumped
in phones advance wifi settings it has this WPS entry - what is this and is it somehow not allowing me full wifi?
i can view playstore,, it checks and loads my gMail but it won't connect to websites
it takes so long to download and install apps from playstore, i have to hit cancel, redownload, reinstall to get it working,etc. its not 'instant' like normal 20Mbps wifi should be
ran speedtest.net app and it wont connect to any servers
if anyone has clues to why my wifi is broken, please PM me thanks
it get a blue 3 to 4 bars on wifi signal but it keeps having this 'black' dot flashing in that wifi signal bar, (what is that?)
shows connected to my wifi at 72Mbps at good strength
I found my solution: in my router I unchecked the option WMM (Wi-Fi-multimedia)-settings (2.4GHz b/g/n). After I activated it, my data speeds increased enormously. Try it & report!

My n4 will not connect to any of the WPA2 AP's around here.
I have the opposite problem. I can connect to my WPA2 router at home just fine but cannot connect to the WEP wifi at work. Well, not reliably. I've gotten connected twice, but was unable to recreate the conditions.

I had speed problems with my 5GHz band at home. Connected, but couldn't get over 1Mbps on my 30+ connection. Connected to the 2.4Ghz band and I get significantly faster speeds. Haven't had problems connecting though.

I've noticed similar behavior, seems like my 5ghz signal strength is much weaker than my 2.4ghz signal according to my n4.
So this n4 is picky about. Certain WiFi networks.configs

Sometimes, my N4 loses wifi connection at work. It's inconsistent. My work wifi is open but MAC filtered.
There have been 3-4 times when I noticed that it lost wifi connection. I had to turn off wifi radio and back on to reconnect.
OTOH, connection to home DD-WRT wifi router is rock solid.

Hello, I am also having problems with WIFI. I've tried a lot of things (change the router configuration, the cellular exchange kernel, etc ...) but I could not fix this problem. Can you give any more ideas? I've even thought about buying another router but can be giving the same problem.
I used my wife's phone as a router and it works normally, but when I connect directly to the router from home and he trasfere data only for a few moments and then transferring data, although still seem the symbol of wifi connected.
I found changing a setting on the Nexus 4 seems to have remedied most of my WiFi issues. Forcing the WiFi frequency band to 2.4GHz only instead of Auto appears to have done the trick for me.
In WiFi if you select Settings and Advanced under Wi-Fi frequency band there is an option to force 5GHz or 2.4GHz with the default on Auto.

Wifi problem - what router do you use and what is the configuration?

Some people have no problem, while others like myself have issue. So let's figure out if this is a router config issue, since most Wifi problem with Android have to do with the router itself. I'll start off with mine.
Tablet date of purchase: September 12th
Router: ASUS RT-N66U dual-band (2.4 & 5 Ghz) with latest firmware
Wireless configuration:
- 2.4 Ghz for B/G
- 5 Ghz for N only
Distance from router to tablet: less than 50 ft
Issue: sporadic network connection. I got full Wi-fi signal bars, good Internet connection, but then cut-out and no connection. Back again after 10-20 seconds.
Fix(?): Changed the router configuration for the 5Ghz radio from 20/40 Mhz to 40 Mhz. This seems to tame the problem. I still have sporadic connection, but far less and connection is back again after a few seconds.

I have a TP link single band N router configured for b/g/n. Both my shield portable and shield tablet have issues with wifi. My nexus 7 and my moto g are perfectly fine on it.
I think in my case I've narrowed it down to the router, though. I have a second router upstairs, also tp link single band N (different model). It is configured in bridge mode for the main router. Both shield devices are perfectly fine when connected to it. Unfortunately it only serves a small portion of my house and is much slower over all.
A robust wifi area will hide most any weak wifi. Catch is most areas are not robust.

I'm using a similar setup, but an ASUS RT-AC66U instead of the N66. A frequencies are mixed-mode, and my 5GHz is 20/40Mhz. I can pull a consistent 20 Mbps down usually, without any issues. 50 Mbps down if I'm the only active network user at the time.
Wifi signal is usually at 2 bars, but I'm getting the same signal level out of the Shield Portable, my Nexus 5, and Nexus 7 on my 5Ghz net. My 2.4Ghz net is usually always full strength.

That's interesting. I wonder if my N66U is unable to maintain a stable and consistent 5Ghz connection. So you have no problem with the connection like mien?
Do you use DD-WRT or stock ASUS firmware (what version?). I may end up buying the AC66U just to test it out.
Using a virgin hub which is a netgear i belive, 2.4 is solid even two stories away from the router. 5g is still there 2 stories up but will drop out, only 1 story up it's 1-2 bars but never drops out. 5g band on router set to 38-40ish range.

Don't you need 5Ghz to play GRID? If I use 2.4Ghz, GRID will "complain" and won't start any game I selected.

Stock. Whatever the latest version of firmware is too- I update when it's available.
When I had problems with my Luxor tv connecting changing channel on router from auto to one of the numbered ones fixed it, perhaps it has the bug where your device ends up getting the same IP as the router. Worth a go!

Wi-Fi connectivity issues

Somewhat of an odd issue with Wi-FI
First the phone is a 100% stock (unrooted) Sprint issued Galaxy S5.
Access point is a Cisco 1142 in Autonomous mode running 802.11n (2.4 & 5ghz with a 40Mhz extended channel in the 5Ghz band). Both IPv4 and IPv6 (utilizing auto configure) are on my network.
Three laptops report up to 300Mb/s connectivity and work flawlessly
Three iPhones work without any issues
Two iPads (Wi-Fi only) also work without issue
Galaxy S3 work without issue
HTC EVO work without issue
The Galaxy S5 connects and works fine for a random period of time, seems to be typically between 1 and 3 hrs and then simply stops communicating, I've tried a static (IPv4) address but to no avail. Sometimes I'll find that only the IPv4 stops working but IPv6 continues to work or vis versa.
One thing I did note was the S5 never reports a speed higher than 144Mb/s regardless of the signal strength. I haven't tried disabling the extended channel on the 5Ghz band, maybe the S5 has a problem with that?
Lastly connecting to an 802.11g AP seems to work reliably.
Any thoughts/suggestions? I'm not opposed to rooting the phone if there is a known issue that is solved by modified code.

Tried disabling Smart Network Switch in WiFi settings?
Should have mentioned that -
Under Wi-Fi advanced
Network notification - unchecked
passpoint - checked
sort by - signal strength
keep wi-fi on during sleep - always
always allow scanning - unchecked
smart network switch - unchecked
Wi-Fi timer - all times unchecked
-TL
The access point "had" two SSIDs being announced, I took one off and the stability problems seem to have gone away, now to figure out if I'm announcing the second SSID incorrectly or something else is going on.

You might be onto something, based upon what I've found and my understanding of Wi-Fi there should be no issue with putting the same SSID on both radios; however I've found that the S5 seems to be switching back and forth a lot and is failing whenever its on the 5Ghz radio. I have since turned off the 5Ghz radio (of course that reduces my throughput to 144Mb/s on Wi-Fi vs 300 but I doubt I'll see a difference).
I've seen some various comments about 5Ghz not working properly for some, I don't know if this is a real issue or not.
Also keep in mind my 5Ghz radio was set for a double wide channel (40Mhz vs. the small 20Ghz) enabling 300Mb/s.

There's no issue until you have a device(such as the s5) that sees both bands, people do this with public WiFi as well, they put up a malicious hotspot with the same name as the public one. I would give your 5g band a different name that's what I do, its just said for 2.4 and ssid-5G for the 5.

all 5GHz wifi will disappear sometime

Hi there,
i found that all 5GHz wifi will disappear sometime and only 2.4GHz wifi were left even the signal is very good.
Not only mine but also my neighbor's 5GHz wifi was gone too so i can confirm that there is no problem with my router.
but it can be solved by restarting WIFI in setting menu.
is that a hardware bug or software bug? have anyone facing this problem too? :crying:
ps: using stock rom 4.5.5 & stock kernel
I've too, but disappear and restore itself.

I have the exact same issue, I have 2 separate routers, one upstairs and one downstairs. The one upstairs is a 2.4ghz router and the one downstairs a dual-band router with separate SSID's for the bands, sometimes when I come downstairs I can only see the 2.4ghz SSID not the 5ghz one.

Have you guys already contacted OnePlus about this? I have a few days ago, and I'm currently still in touch with them to find out why this happens.
I for example have the problem, that sometimes the data throughput using 5 GHz networks is absolutely zero, no data is transferred at all (tested with iperf3) and then sometimes it resumes but other times I have to disable WiFi entirely (disable background scan to do that) and reconnect and only then it would start communicating again.
BTW: I'll include a link to this thread on my ticket with them, so that they can see I'm not alone with WiFi issues on the 5 GHz band.
