Ok so im tearing my hair out here and im about to break something ....
Hopefully some brightspark in here might have a clue whats going on! im a computer tech by trade and this has me stumped.
Ive got two machines, one windows 7 directly connected to the router.. 2nd pc is a XP machine connected to a Dlink 2100ap which is set as a client. Router is a 3com officeconnect.
The xp machine gets an IP off the router through the AP, it can browse the net fine. I can ping the router and AP, login to both as well.
From the 7 machine i can log in to the router fine. Cant ping the AP and cant ping the xp machine. There are no firewalls and no AV enabled on either machine.
If i swap the connections over so the 7 machine has the AP and the xp is hard wired in, from the 7 machine i can ping the xp machine which is freshly loaded, only things on here are drivers, all windows updates and media portal and its sql servers etc.. no firewall or anything has touched this machine, xp firewall is off too) What the heck is going on!
Ive reset router and AP to factory defaults..
I thought my dlink maybe faulty as it was a year old so i tried a brand new 2100AP.. Excatly the same problem.
Turned off all firewall features on the 3com.
Looked through the AP settings for anything that could explain this.. No vlans or anything enabled.
Ok so xp machine aside.. I should be able to ping the AP, if i cant ping the ap chances are i wouldnt be able to ping the XP machine. The kicker is, that the XP machine can surf the net etc through the AP, so its on the network.
Thoughts? Ideas? Anything?! lol
