I have the following situation:
I have a Win7 laptop from work. I have successfully used it with a few different wireless networks, so I know that the wireless card etc. in it work.
I have a WiFi router at home that I use on a regular basis with my personal laptop (also Win7), an Android phone, and occasionally other laptops, so I know that the router, configuration, etc. work.
Now, the problem:
If I bring my laptop home from work and try to use it with my wireless at home, it doesn't work. The most confusing part is that it does work about 1 in 5-10 tries (so if I try to open a webpage and press refresh a few times, I eventually get it, though often without images etc.)
If I connect the laptop directly to the router via Ethernet, it works fine.
So the problem seems to be somewhere with the configuration of my laptop and my router, but I am at a loss for what it could be. Any hints would be appreciated.
A few details that may or may not be relevant:
Wireless security is WPA-2 AES
Router is a LevelOne WBR-3406TX capable of b/g WiFi.
The laptop that doesn't work is a Lenovo Thinkpad T430, capable of WiFi b/g/n. I don't know details of card etc. offhand, but can check if needed.
I am not sure, but I feel like Dropbox never has a problem, but the web browser and the VPN connection have the problem. It may just be my imagination.
