I've been having this problem for around two years on my current laptop, but today it finally got so frustrating I had to ask about it. I've tried and tried to search for others with a similar problem, but have never found a good solution. When my computer turns on and connects to an internet source (LAN or wifi), it will work fine indefinitely. However, if I join a different LAN or wireless network later, such as when I go from home to school, it will connect to the new network, but after a few minutes, I will be unable to load any web pages (Connection timed out).

Skype and email still work fine, and the only browser I use is firefox, so this may be a firefox-specific issue. If I reset the network adapter being used, then I will be able to load websites again, but after 2-30 minutes, I will run into the same issue and have to reset the adapter again. Joining a different network does not resolve the problem. Restarting firefox does not resolve the problem. Clearing the firefox cache is a temporary solution only, similar to resetting the network adapter. Restarting the computer entirely will result in no connection problems, until I have to change networks again.
Specs are below, and again, I connect to the internet using firefox 14.0.1 Tech Support Guy System Info Utility version 18.104.22.168 OS Version: Microsoft Windows 7 Home Premium, Service Pack 1, 64 bit Processor: Intel(R) Core(TM) i7 CPU Q 720 @ 1.60GHz, Intel64 Family 6 Model 30 Stepping 5 Processor Count: 8 RAM: 4030 Mb Graphics Card: NVIDIA GeForce 310M, 512 Mb Hard Drives: C: Total - 464783 MB, Free - 133483 MB; Motherboard: TOSHIBA, Portable PC Antivirus: Microsoft Security Essentials, Updated and Enabled
