[Q] 802.11n network not visible -- Issues / how to debug ? - Eee Pad Transformer Q&A, Help & Troubleshooting

Hello all,
I have set up a 802.11n network in my Netgear WNDR4000 (European setting, channel 44).
Problem is that the network is not visible in my Transformer TF101G (Wi-Fi version v5.2.64, kernel v2.6.36.3-00004-g15c5e57).
I tried both open/unprotected and WPA2-PSK security but with same result. Even tried to add it manually, but not visible.
Network works fine in my Win7 laptop (but not in Galaxy S phone either)
Any suggestions / ideas on how to debug / fix ?
Thanks,
Florian
P.S. 802.11 b/g works fine.

Do you use the 5Ghz on wireless n? That is because the Transfomer does not support the 5Ghz. Try 2.4Ghz, that will work.

Thanks, that explains it
Gaah... Truely assumption is the mother of all ****ups. I was all the time under the assumption that 802.11 means 5 GHz -- and viceversa.
Thanks for pointing that out Pierre. Just another reason to look fwd to my next tablet (5GHz radio

3G and Wifi?

Hey, so I just picked this up but I can't connect to 3G or Wifi?
Have you gone to the settings menu and wireless, turned on wifi, and then selected a network? Are you using your own wifi? Is there wifi available where you are? Is there 3G available where you are?
We need to know the steps you've tried so we can help you.
Wifi - it tells me it is connected, but cannot browse unless I disconnect wifi when it happily connects using 3G. I can check the router and it has the Samsung's MAC address on its list of connected devices. Anyone else having trouble with wifi?

Someone else was having problems with 5ghz vs. 2.4ghz in their router. Are you broadcasting wireless-N at 5ghz? Have you tried rebooting the router, and a battery pull on your phone?
I don't think I am broadcasting at 5GHz - what should I be broadcasting at? Yuck, I turned off wireless-N so it is only broadcasting b/g and now it works...
Weird - now I turned wireless N on too so the router is broadcasting a/n-b/g and everything is happy. I actually specifically turned *on* 5Ghz/2.4Ghz too so it has both (Airport Extreme router) that it will talk and the router tells me that the Captivate is talking 802.11b/g/n and now the phone is happy. Thanks for pointing me in the right direction - it was driving me nuts because I could see the wifi at Starbucks!

Brighthouse Motorola Surfboard SBG6580 Help Please!!

I have tried to connect the touchpad to the wireless unit and know that the numbers are correct because the wpa personal code was accepted by my netbook and blackberry 9700. I do not know if it is a setting with the modem or what?
Wrong Pew?
Not sure this question belongs here, but...
TP only supports, b and g, not n. I was unable to to connect to 5Ghz band no matter what. Only 2.4Ghz.
Try connecting with no security first: no WPA/2 etc. Then implement security.
What works with my Moto SB wireless is either WPA-PSK or WPA2-PSK with TKIP.
I was unaware of the 5ghz. I knew it was just b and g. We will try those settings! Thanks!
my touchpad works on my routers 5ghz n band and 2.4ghz band just fine. using wpa2 tkip + aes. so the hardware is capable.
Thanks autoprime. I will give that a spin. Brighthouse changed the password to access the modem setup but they can probably figure that out.

[Q] WiFi disconnects while showing it is connected only on Android

Hi,
I have multiple devices at home using the WiFi fine (iPad, Laptops...)
But with two android devices (Nexus 5 and Galaxy S 4, both on unmodified) I have the same problem.
It connects to the network, and works just fine, but after some time, there isn't any internet connection, although it shows as if it's still connected.
By disabling and enabling Wifi I get internet connection again, but it's really annoying.
Here's my setup:
Edimax router as AP
2.4 GHz (B+G+N)
Visible ESSID
Channel number 6
Encryption: WPA 2 (AES) pre-shared key (passphrase)
No MAC Filtering
EDIT: This router is a switch with wireless, it is connected to a diffrent router that is connected to the internet.
What can I do? Should I modify any of my WiFi settings?
Thanks!
did you try to disable energy saver?

If asking you're whether I had disabled the WiFi optimization in the WiFi settings, yes I have...
I have just only remembered that this router is actually a switch with wireless. The internet is connected to the other router, which is connected to the router i'm asking about (EDIMAX) which acts as a switch.

[Q] No 5ghz wireless detection with Lollipop

Hi all,
Strange problem following my OTA lollipop update yesterday. My (UK WIFI version) Shield tablet is unable to detect my router's 5ghz signal. Kit Kat had no problems and all my other devices can still see it fine. I have also tried changing the settings on my router to see if Lollipop is more fussy about frequency/band etc, but still no joy
Anyone else having strangeness with this? Or is it just me?

I flashed the US ROM last night, and during setup it took maybe an additional 20 seconds before the 5ghz routers (including mine) to show up in the list. 5ghz has always been kinda weird for me though. On a few occasions I've had to disable WiFi, wait 10 seconds, then restart so that the tablet will connect.
I also have the UK wifi version, and my tablet even connected first to the 5ghz network, I was actually surprised.
No issues here with 5ghz wireless.

Thanks guys,
It's very odd, because I run wifi analyzer at home and it doesn't show my 5ghz network at all, yet in the office it does show the 5ghz one.
It was working before the update and all my other devices can still connect fine, so a real mystery

Reboot the router?
I'm having this issue with my Nexus 4: http://forum.xda-developers.com/nexus-4/help/lollipop-5ghz-wifi-t2945330
Upon further inspection, it appears the only 5ghz channels that work are the first couple in band A (36 - 48) Nothing else seems to work.
Can anyone else confirm this behaviour? Try using a 5ghz channel other than 36 - 48
Band A : 5150 - 5350 MHz (channels 36 - 64)
Band B: 5470 - 5725 MHz (channels 100 - 140)
This is pretty rubbish if this is the case, as the band B channels allow a higher output and give me a much stronger signal in my house

I can only connect when I use channels 36-48, Band A UNII 1. Can't even detect the AP with WiFi Analyzer on the shield if I go above 48.
Using the non-US 32GB LTE version in the EU, btw, same frequencies are allowed here as in the US.

Sorry, you're right 48 does also work.
So that's confirmed then, they have for some reason heavily limited the 5ghz channel selection! I wonder why?
It's not a hardware limitation as it was working fine with KitKat, so I wonder whether it's possible to get the other channels unlocked?
Just to be sure, ClownShoes, does channel 140 work for you? I can't test this because my fritzbox router doesn't have an option to change channel width to 20MHz, and channel 140 isn't available to me for this reason.
Same problem for me here. No 5ghz detected when my Xperia Z1 Compact detect it . Even Wifi Analyzer can't see it . I restarted my tablet & stuff, nothin' . I'll try to make a nandroid backup, make a fresh install and I will see the result.
Same problem for me here with my samsung galaxy note 3 32 gb(sm-n9005). If I restart router phone view and connect to 5 GHz. When phone leave coverage are for same hours when come back don't see 5 Ghz wireless. This is strange because I have another phone with windows which work perfect. I will try to change wireless channel if don't work, I thing serious to go back at android 4.4.2
Update: I changed channel from auto to 48 and works.
Just dropping in to say I had the same issue: I had my router on channel 112 and the Tablet wasn't even seeing it.
Switched to 48 and everything works fine now.
Same issue here, hoping Android 5.1 fixes this silly issue. I was wondering why i couldnt see the 5Ghz network at channel 140, 80mhz. had to bring it down to channel 48.
US wifi version here. 5.1 Lollipop, stock rooted.
I can connect to channel 149 with turbo mode (40MHz channel width) & the upper Extension channel, but WiFi analyzer shows my router is broadcasting on channel 153. I tried so many other channels & combinations but this is as high up as I could go & have the tablet connect. It did, however, see channel 161 but got an authentication error & wouldn't connect with the router.
So, back to 149. The signal is slightly stronger & have better throughput than channel 48!
On a side note...I use 5GHz here in this LARGE apartment complex because everyone here is on Verizon FIOS or Cox Communications, so Wi-Fi Analyzer sees 17 (give or take a few for signal strength or weakness) access points around my place & the 2.4 band is completely choked up! There is only 1 other router close by on 5GHz, so using that band is the only option for wireless internet here. I don't use Verizon's wireless AP. They only have 2.4 wireless, no 5. My Netgear simultaneous dual band router is plugged into the back of their cable modem & my Netgear is on 192.168.2.1. That way I can use DD-WRT & my own router instead of theirs for wireless. Easy-Peasy!:good:
I have the same issue. After switching my channel from 100 to 40 the 5GHZ wifi showed up on (two) shield tablets just fine
I believe the SHIELD Tablet only supports United States Non-DFS channels, so 36-48 and 149-165. I personally have mine on Channel 149 and 80MHz bandwidth.

MemoPad Smart 10 (ME301T) stock can not connect to 2.4Ghz WiFi

Just received my ASUS MemoPad Smart 10 , had this issue out of the box. It won't connect to most 2.4Ghz Wifi. Can see networks and tablet will try to connect for ~5 seconds then network just sits there as 'Saved'
What I tried:
1. Asus n56u router - 2.4 Ghz does not work, 5 Ghz works perfectly
2. D-Link Dir-615 router - only supports 2.4 Ghz - does not work
3. Tethering AP on Nexus 5 - does not work
4. Asus n66u router - weirdly both 2.4 and 5 work perfectly on this one.
I am running latest stock (it did not work on out of the box rom also), tried to change frequency settings (Auto, 2.4), rebooted routers, tried wpa2-personal and open network. All other devices work perfectly on all networks.
Don't know what to do now.
