Hi- Please see this question:
I thought it had been answered because this didn't happen for almost a week, but it has happened again.
More info: That laptop can still send and receive email, although the wireless icon shows no internet access. Cannot get onto any websites.
-One of the checks you can do is ping 184.108.40.206 when the internet doesn't work and let me know whether the ping goes through or not.
YES, 220.127.116.11 GOES THROUGH
-try resetting the NIC with netsh commands as administrator
netsh int ip reset
netsh winsock reset
DID THIS-DID NOT TRY UPDATING THE NIC CARD, WILL TRY THAT NOW
- check to see if your wireless adapter still has an IP
- YES , IT IS 192.168.X.X. i CAN PING THE DEFAULT GATEWAY, AND CAN GET INTO THE ROUTER. EVERYTHING LOOKS OK ON THE ROUTER.
-I would suggest trying to run ipconfig /flushdns. If that doesn't work check the router to see if it stores an ARP cache then flush it.
Also check the host file for wierd entries. Could also be a virus.
HAVEN'T DONE THIS, NOT SURE HOW TO CHECK THE ARP CACHE, BUT WILL TRY THE DNS FLUSH. WILL FIGURE OUT HOW TO CHECK THE HOST FILE.
I'll let you know what comes of updating the NIC, flushing the cache and checking the host file. Thanks.
