I have a wireless Toshiba latpop 1 1/2 years old, running Windows 7 that I have been connecting with at my college for a year and a half with no problems. This same laptop connects to my Fios wireless at home with no problems. My trouble started 6 weeks ago and I have been trying to solve this problem ever since day and night! Ugh Start computer - I see their college network. I chose it to connect or sometimes the checkmark is there to chose automatically. It will not connect. I get the yellow triagle with words limited connectivity, no internet access. If I use the troubleshooter. I get no default gateway. It is fixed. I sign in on their log in page and within 20 seconds it drops me every time. I mean everytime. Not just sometimes. --I have spoken with their local IT people to no avail. -- uninstalled any programs that I put in in the past 3 months. -- uninstalled my firewall --shut off windows firewall --reinstalled my Realtek Nic card with 3 or 4 different versions, rolling, upgrading, and installing brand new one from net --unchecked power save on the Nic card -- flushed the dns cache -- ipconfig, release renew -- ran the troubleshooter at least 100 times. -- repair install of windows 7 -- ran 4 antivirus program, malware programs, all clean -- added all windows updates, although most had been in anyway --registry cleaner, 2 of them. --checked with IT that my log in is correct and not blocked --deleted all networks and setting up connection to college and fios again. -- unchecking IPV6 on the Nic card. plus many other tries that I can't remember. Several of the above do give me a temporary connection to the network but it drops in 20 seconds everytime. I cannot get on the network without the troubleshooter then I get 20 seconds and I am off. Please help. I have asked everyone I know. Someone here has to know what to do. Thank you. FYI I spoke to sort of a network adminstrator today at the college. He said he has heard of this problem from about 3 other people and coincidentally we all have Toshiba laptops. Anybody with a Toshiba laptop having this problem? I was working fine on their network and now I cannot get on or stay on. What could they have changed at their end that my laptop doesn't like? I don't know these things.
