When I travel to different wireless environments I am unable to get online even though it says wireless connection is excellent. One diagnostic through msn messenger troubleshoot says my default gateway appears to be offline. I can connect to my home wireless no problem, it is only when trying to connect to other wireless networks I have the issue. I am using AVG free anti virus also. Sometimes when I try to open a webpage in firefox the it says avg.urlseek can't fine address. After fiddling with this through various help searches, now firefox says the specific webpage I am looking for (go.microsoft.com) cannot be found. I'm a novice with all this. Any help most appreciated.
