You can associated with the AP 00:18:0a:33:8a:c0, which means you can send and receive data.

It is somehow loosing conenction. Possibly because your AP is configured to a frequency that is not available in the US regulatory domain, because it reassociates after changing the regulatory domain back to the default. If you are not located in the US you might want to figure out, why it tries to impose US regulations.

I am in the U.S., but I believe the issue is that my wireless card isn't receiving power, as is indicated by the Tx-Power=0 dBm.

I don't know how to give power to the wifi card, if anyone can, please post a command to do so.

Thank you for your time.

Tx-Power= X dBm means the transmitting power of the wireless signal, and its measured in Decibel-milliwatts (dBm).

It has nothing to do with the electrical power that supply the WiFi module of your laptop.

In order to troubleshoot your issue more easy, you can try to connect to a open network on a different location (like Starbucks or something),

and if you succeed, then you can be sure that your problem is with the configuration of your AP, As _jr_ said.

Yes, should have been clearer.

I'm not really an expert, but the 'wlan0: authenticate with 00:18:0a:33:8a:c0' and 'wlan0: associate with 00:18:0a:33:8a:c0' entries in the log mean that your card is seeing an (your?) AP and trying to connect by sending the appropriate requests. The 'wlan0: authenticated' and 'wlan0: associated' imply that the low level part of the connection was successful, i.e. your card is actually receiving the responses to the requests it has sent to the AP. It might not neccessarily indicate that the encryption (if any) was set up correctly or that DHCP was successful. It could just be, that you are not using the correct encryption scheme or password. The regulatory domain switching could be a red herring.

 

[fritata]

Well, I can connect and browse the web for about 45 minutes before this shows up, then, after a reboot, this issue continues.

EDIT:

I can connect to all types of encryption.

Unencrypted networks yield about 45 minutes of usability.

WPA/WPA2 networks work for about 4 hours before this starts happening.

DHCP lease expiry maybe? In my experience, many routers' DHCP servers are absolute crap in Linux, and when it comes time to renegotiate a lease it can stuff up.


I forget how you can see how long your DHCP license is set to expire. You could always try setting a static IP and see if that helps.

 

[ThinkPad]

@rand,

With this new additional information that you provided, I think this issue is caused by the driver of your WiFi module.

I suggest you to find a proper and more recent driver for it.

@Levi,

There is no such thinks like crappy DHCP of the routers. Crappy Linux drivers for the network adapters and modules of the end user machines is the most common reason for that kind of problems.

 

[levi]

Well, I assumed it was the router only servicing DHCP broadcasts periodically, such as once a minute, and the client timing out before it got a reply. Seems something like that on my netbook, since 80% of the time it'll connect okay, but the other 20% it'll fail when negotiating the second dot on the network manager icon. I've also had problems getting my desktop running Arch to connect to the same router, but that one won't connect at all if I try to get DHCPed settings, but setting everything manually works fine, and it stays on the network better than my netbook does.


But yeah, I don't know what the problem is exactly, just that bypassing the DHCP server on my Arch box seems to fix it.

 

[fritata]

Well, Thank you all for the help.

Apparently, my wireless card, the Intel 7260, is notorious for having issues on all manufacturers' computers.

I tried back porting or something like that, but still have issues like many users with this card.

I'll have to settle for a USB wifi card instead.
