Skyrocket Wifi 5Ghz - AT&T Samsung Galaxy S II Skyrocket SGH-I727

Hey all,
i am having some issues with my 5Ghz wifi and my skyrocket. First I will list all the information I have.
Skyrocket i727.
Roms I have tried to connect with - Embryo 7 Cymbaline and stock kernel ; Beanstalk 1.30 v.1. with mortez and marla. No luck.
Router - Linksys WRT320N - not a dual band. either 2.4ghz or 5ghz.
Open dd-wrt firmware on the router.
Wireless settings - N only (5Ghz) - 40mhz wide channel - lower - channel 52 + 54.
Security - WPA2 personal with AES encryption.
i have tired many things to get this wifi to connect on my skyrocket. I have tried switching to wirelss A and N. No luck. I have tried using on 20 Mhz wide channel. No luck. I have also tried taking Security off completely with Wireless N 5Ghz and no luck there either. Only way I can get it to connect is using 2.4 ghz. I know the skyrocket supports 5Ghz because there is an option for 5Ghz only within advanced wireless settings.
Any help or advice will be greatly appreciated. Thanks.

Have you tried it with stock? Also try scanning the channels with WiFi analyzer. They have an app that might help you connect.

No I haven't tried it with stock. I do have WiFi analyzer installed and everything seems to work fine on the router end. I'm getting fantastic speeds on my laptop and my friends s4 connect instantly and gets great speeds as well. So I know its not the router settings. I have considered stock Though.

But when you use Wi-Fi analyzer on the skyrocket, does the phone "see" the router. Have you tried restarting the router with nothing connected to it, and connecting the skyrocket first?
Edit: Try using different channels as well. Not sure exactly what channels the skyrocket can see in 5 GHz mode.

Yeah it sees the channel on WiFi analyzer. I've tried channels 40,42 ,149 and many others. It seems to have a problem authenticating the WPA2 key. But, going by that logic, leaving the network open would solve the problem. But it doesn't. Still can't connect on 5ghz when there is no security. So, I'm thinking Its a custom kernel problem or the hardware is failing. Not sure which.

Yeah I would say try another router someone else you know has that has 5ghz and using stock router firmware. Are you on the latest dd wrt?

Yeah the latest as of like march 2013 I believe.

I am using a linksys e4200 dd-wrt build 22000
Here are some of the settings I use:
Basic settings:
wireless channel : 153 - 5.7654 GHz
Channel Width: 20MHz
Wireless Security:
Security Mode: WPA2 Personal
WPA Algorithms: AES
Advanced Wireless Settings: shown if different than default
CTS Protection Mode: Disable
Preamble: short
TX Power: 66 (lower than default)
Afterburner: enabled
You might try playing with the TX power setting since the default (for my router) is the same as the 2.4 GHz default and is to high for the 5 GHz band.

Well. I tried those settings but still a no go. I think its a problem with the 5ghz on my phone. Maybe I need to go back to stock JB. Not likely though. I resolved the issue by using two routers anyway. One for 2.4 and one for 5. Works perfect so far. Thanks for everyone's help and Input.

[Q] Wireless Access Point Switching

If this has been asked and answered, I apologize. Can't figure what to search for to find it.
I have a multi-story house and one wifi access point simply doesn't cover it all. I've wired up one for upstairs and one for downstairs. One of the two has DHCP enabled. Both have identical SSIDs and security. I do not know to change BSSIDs (some kinda hidden SSID?) Have tried setting both to same channel and to different channels - currently on 7 and 11.
My charge will not automatically switch between them. Under EE4 I could turn off wireless and when I turned it back on it'd connect to the stronger signal. Under all the gingerbread builds it connects to one and even after turning wireless on and off it connects to the original one. Under GB I can only switch between them using Wiifi Analyzer's connect feature. Under GB I've taken to setting up the SSIDs to different values so I can at least manually switch between them in settings. This is a royal pain as I walk between the two floors all the time.
What am I doing wrong? Doesn't anyone else have this problem?
Instead of multiple routers, try using wireless repeaters or extenders. A repeater picks up a wifi signal and rebroadcasts it for better reception. A network extender has an ethernet port that connects to your router and makes an access point without making a new network.

I prefer dd wrt routers using WDS. There are lots of resources about this. Or just buy a some access points. I find that repeaters have interference issues.

Well, actually my second router is currently setup in firmware to be an access point.
Have either of you guys observed a Charge w/ GB actually handing off correctly? If so, at least I'd know that it's my setup.

A repeater is the best solution? The upstairs location just barely picks up the wifi from downstairs. Seems like you'd lose a lot of thruput that way.

Tried the app "Wifi Manager"? It might help you. There a bunch others. I would try them all out to see if they help your situation.
WiFi Jumper fixed this problem for me. Well worth the money.

Seems like a nifty utility. Easier than setting up WDS, but I still think that WDS is the bees knees when it comes to having rock-solid wifi everywhere you want.

Cant find wifi!

HI, we recently bought an 802.11n compatible router called Asus RT-N13U and its visible to every pc in the house inclufing the xbox 360 and the ps3 but its totally invisible to my nexus s its like it doesnt exist. We have tried disconnecting everything but still didnt work. I need help and this phone is not rooted.

Probably broadcasting on a channel which Android has disabled for your country. Switch to a channel between 1 and 12 on your router, may need to take off auto. An app like Wifi Analyzer should be able to see the network no problems.
Its on channel 11. My old was on 11 too but it worked...

Make sure you have set your router to use the 2.4GHz band, not 5GHz.
It is set to 2.4 ghz and wifi analyzer cant see it

Be sure your router was configured to WPA/WPA2 security,not WEP,and that the router is visible (Wireless SSID : ON) .

Wifi issues

I just got my 7.0 and love it but the wifi keeps disconnecting. It'll reconnect but it messes up my downloads. Does his seem to be a problem with the 7.0 or did i just get a bum model?

did you updated your tab?
Try removing n/w and re enter wep/wpa key...
It should work
As i know their are some problem with routers with 5 ghz channels so try the 2.4 ghz channel and see if the condition resolved also try a different channel to broadcast by you router as channel 8 or 13 etc and see if connection improved or not if you could try it with different router and different connection as in your friend connection to see if connection still drops or not if still drops then return with warrany if no warrany may be you could think about flashing modem files by odin but i think it needs somewhat experienced users and may void warrany

Slow Downspeed on Note 10.1

I have a fiber optic internet connection at home and on my desktop PC I get download speeds of 80mbps+ however when I do a speed test on my note 10.1 I am lucky to get a downspeed on 3mbps. Does anyone have any ideas why this is and how to improve it?
I am in the UK and have the N8010 model.
Many thanks.
Its likely something with your router. Check the signal strength and channel.maybe a firmware upgrade on the router .are you connection to a/b/g/n all of the above will effect speeds and reliability.
Also is your PC hard wired.? If so you know it will be much faster there is far less overhead data tagging along.I do not think its the device
Good luck

Thanks for the response. My router in running on Wireless N. Yes my PC is hard wired however im still getting at least a 50mbps downspeed on my Windows laptop via the wireless. I just figure it's something to do with the network card inside the Note?
I do have some problems connecting to certain networks with my tablet as well. Maybe there's some problem with wifi drivers in the galaxy note I'm guessing. Hopefully it'll be fixed in JB.

One thing you can try is changing the encryption and/or privacy standard (WEP and so on) since some of them isn't supported by "dumb" devices and I suspect some of them are supported but are so advanced it affects the performance.

Hi,
I had the same issue.
I solved setting the ip address to static (not dhcp) in wifi settings.
Now i get 20 mbits+ (consistent with my G router capabilities)

Go to settings.
Select wifi
Long press on your connection.
Press modify connection
Now select ip settings and change to static
Now change your IP to an address outside of dhcp range and your done.
If dhcp is 192.168.1.2 through 192.168.1.100 set your tab to 192.168.1.101
You can also change your routers dhcp range to 192.168.1.2 through 192.168.1.15 and set your tab to ..16
Your numbers may be different, but same method.

Different WiFi networks

Hello all,
So it seems as though the WiFi network at work is draining the battery on my phone way faster than my WiFi at home. What would the cause of the exponential drainage at work and not at home?
We have Ruckus wireless network setup at work, and I have an ATT 2Wire wireless router at home.
My work wifi was crazy noisy... Use the app Network Log to check traffic when you're at work and at home.
The thing to check for is if the the kernel sends and receives a lot of packets at work. If it does, try switching to ktoonsez's kernel over in Original Android Development. He implements some TCP congestion code that silences my work wifi.

So it seems as though my work WiFi is pretty noisy. I currently on IMOs 1.5 kernel and am skeptical to switch. But I will try it out and see what happens
