The settings we note in the forum sticky?
And since you didn't share your settings, I can't guess if it's a common problem or if your firewall has gone to block everything. I don't know much about your settings so I note our sticky first.
I am stumped. My wireless router (D-Link DI-514) can be used to successfully connect to other wireless computers in my home. My Compaq computer running XP use to successfully connect to my wireless router via a network card and bring up web pages, but now appears to connect but not bring up pages. The computer that doesn't connect to my home router connects to Starbucks and other free internet sources with no problem. When it doesn't connect at home, it shows to have a strong signal but displays a message that says limited or no connectivity. My ISP says that everything is working (as verified by the fact that I can connect wireless to other computers).
I don't know what I'm doing and think I have switch something off in my attempts to fix this. I tried to "ping" the router (I don't know what this means) and could not.
Any suggestions to help?
