When my ADSL provider is down as it frequently is, I have used my Blackberry (Bold 9000) tethered to my laptop (Win XPSP2) to access the internet (3G) and recently though it would be neat if I could hook up a Wifi access point to my laptop to share the connection wirelessly around the house.
I have used the network setup wizard to share the connection with other computers - in my case it is only one additional desktop (XP SP2 also)which normally accesses the internet wirelessly through my ADSL modem/router.
I got it all set up with the BB hooked up to my USB port on the laptop and a wifi access point connected to the laptop via the RJ 45 ethernet plug.
The strange thing is on the desktop computer, I can get an IP address OK, and can do an IPCONFIG/NSLOOKUP and see the www.microsoft.com
server, I can also ping the DNS server of the 3G provider my BB is connected to.
However, I cannot for the life of me, get the internet on the desktop, despite being able to ping any address I want and including the DNS of my provider. The laptop is still able to access the internet.
A friend suggested a ipconfig/release then dnsflush then renew (tried it on both computers), then my ISP suggested doing a winsock reset by ipconfig/NETSH i i r log then netsh w r none of that helped either.
I am completely baffled by all this. I am suspicious it is some kind of DNS issue but wonder if any networking experts on here can assist me to fix the problem.
