Help Does your DInc drop wifi connections? What is "recieved deauthentication" (router log message)

[kjarrett]

I have a DLink DIR-655 router (awesome BTW) on my home LAN and my DInc seems to randomly disconnect when idle. This would not be a problem except I am using the Setting Profiles app, configured with a rule that turns OFF wifi when I disconnect from my home LAN. (SP is awesome and does exactly what I want - turns wifi off when I leave for work and then turns it on when I get home.)

Here is my question: I am wondering what wireless security settings I am using that might contribute to unstable connections for my DInc. When it disconnects, SP turns wifi off, and so then it will never reconnect unless I intervene.

I am presently using WPA2 only, AES cipher, 3600 second group key update interval. My key is 26 hex characters (a throwback to the one I used with WEP until recently). I tried running WPA only but the DInc only connected at 802.11g speed. Running WPA2 I connect at 802.11n speeds.

My router logs show an entry with the phrase "received deauthentication" for the DInc when it drops out. Obviously, I also see wifi "off" on the phone at that point as well.

Hope some of this makes sense. Thanks!

The de-authentication message you are receiving is your router letting you know that the phone disconnected(due to the wi-fi being off or the key being lost some how). You are most likely on the right track with messing with your security settings. I'd try going WEP64 and work your way up from there.
Lastly, in my opinion you aren't really going to see that great of a speed difference between the g and n connection on the INC, so I wouldn't worry too much about it. You can run a speedtest to confirm.

Thanks. Just set up a 'guest' network running WEP64, maybe that'll do it...I don't need the 'n' speeds on the DInc, but do for other devices, so, a guest network is probably my best bet.

Well I thought I'd solved this but no luck. Running WEP64 is a little better but it still disconnects periodically - when idle, mostly. Is there some setting I need to check?

Too bad running an open wifi connection is out of the question or I'd try that.

Just wondering why the DInc would drop signals like this. Annoying...

When you are in the wifi settings, hit menu then advanced and make sure your wifi sleep policy is set to never.
Or maybe setting the phone to use a static ip will help. I've personally never had an issue with the wifi, my laptop is less reliable.

 

[kjarrett]

Wifi was already set to never sleep. Thanks though.

Had thought about giving it a static IP. Also thought about going w/o any security and just using MAC filtering. (I know MAC addresses can be spoofed.)

 

[sdrawkcab25]

You have the same problem with every router you connect to or is it just the one? Might be having a hardware problem, or the incredible wireless adapter just doesn't like your brand router.
Mac filtering might cause you even more problems.

Only use it with this one router at my house, which I'm not changing, it's a DLink DI-644 and it's fabulous. Might just have to live with it!

 

[sdrawkcab25]

The next step in troubleshooting would be to try someone else's router just to see if it is a hardware/software issue specific to your phone, but if you are willing to live with it, i guess don't worry about it.
Maybe if someone else here with the same router as you can chime in.
Or haven't mentioned if you've tried different channels on the router?

try to set the "Router IP Address" to 192.168.1.1 then reboot the router and try to connect wifi client again... it may helps to solve the problem in question.
