Wireless issues when using cellphone signal booster

[eeefurious]

Edit:
I'm not sure if this is a new issue or just an extension of my previous issue (below). I have a "network extender"/signal booster from Verizon to give me cellphone reception through the internet. http://www.verizonwireless.com/b2c/device/network-extender The signal booster is connected by ethernet cable to my router. When the signal booster is in use to make a phone call, my internet connection stalls. I am still connected, and as soon as the phone is hung up connection is fine again without having to reconnect. I am the only one (out of at least six wireless devices) with this problem, and it has only popped up with my upgrade to Mint 13/XFCE. Getting rid of the signal booster is not an option as the cell signal here stinks.

I have been having an issue that has not happened before with my wireless.

I am using an Atheros Communications Inc. AR242x / AR542x Wireless Network Adapter (PCI-Express) [output from lspci]

Frequently, but only on my home router, I find that my computer will fail to load webpages while I am for all other purposes fully connected to the internet. I can still send text via Pidgin, pinging my router or to 8.8.8.8 but I am unable to load common websites or ping common websites like http://www.google.com or http://www.yahoo.com.

It seems to happen randomly after reconnecting to the router, but within 15 minutes, making this a very disruptive problem. I've played with adding nohwcrypt=1 to the ath5k module to no avail.

No other computers using the router seem to have this problem either with wireless or wired connections.

This only started happening when I upgraded to 13/XFCE but I'm still using Network Manager to connect to my router.

Can anyone give some suggestion for fixing this or what the problem might even be?
