I share my internet connection with multiple PCs at home using Linksys WRT54g2 router. Its a pretty nice router with easy to use interface and good features for internet sharing via LAN and WiFi. Recently I installed Windows 7 on my main PC and I started facing this problem of webpages not opening all of a sudden. Everything else like torrents, mirc etc would work fine, but the website wouldn’t open untill i reset my DSL Modem, or the router itself OR just reset the LAN card (through device manager/ network window i.e. disable then enable connection)
I even reset the router settings and set it up again in the hopes of fixing the problem, but every once in a while my browsing would stop working whilst everything else would work.
Today i noticed my other PC that is connected to the same router, had internet and browsing working just fine whereas browsing stopped working on my main PC. In the hopes to fix the problem, i experimentally noticed there was Hamachi 2′s virtual network device in the same network connections window. As soon as i disabled the Hamachi network, my browsing was back to normal. So browsing issues with WRT54G2 were due to Hamachi 2 (I remember having Hamachi 1.0 on vista earlier, never had this issue)
It’s such a relief having my browsing back and to have solved the problem. Posting it in the hopes it fixes someone else’s headache if they’re experiencing the same.
