Unable to Renew IP Address

I have a wireless network using Linksys Router with Security Enabled. I have been using my Toshiba Laptop (along with Dell as well as Acer Laptops) to connect to the internet using my Security enabled Linksys router with a cable Modem.


For the last 2 weeks I have not been able to connect my Toshiba laptop to the wireless network using my security enabled Linksys router.

I can connect same Toshiba Laptop with an Ethernet cable to the Linksys router as well as plug it directly into the Cable Modem and it works just fine.


Also, my neighbor has an unsecured Linksys Network and I can connect wirelessly to that network also.

My all other laptops (Dell and ACER) do not have any problems.


Any ideas?


Thanks for any help available

Re: Unable to Renew IP Address

What is your operating system or version of windows? What is your antivirus?

what sort of IP address are you getting..? Which type of security did you set on the router?


If you're getting an ipaddress that starts with 169... its' an auto generated ipaddress which means your not getting the right one. When you check network and sharing center you may be connecting to UNIDENTIFIED network eventhough it shows that your connected to your own router.. ? if this is true, I suggest you try to remove your antivirus.. If you have norton 360 that just got expired or already expired, I suggest you use norton removal tool to get rid of it.. It might help..



If above solution does not work, try to unsecure your router to see if it connects.. if it connects then try to start with most basic security which is WEP...


If you try to connect and you get a message saying "windows could not connect to this network.." then check your router settings.. Call router manufacturer for additional support. Thanks!
