Hello all, new to the forum. I've had this problem for about a week now with little improvement. Here's the deal: About three weeks ago my roommates upgraded from DSL to cable internet. There's four laptops and about four smart phones on the network. There is a wireless router, a Linksys WRT160n V3, which has plenty of punch behind it. Everything was running smooth, I could hop both my laptop and smart phone and browse the net, about a week a go that all changed. I opened up my laptop and and got the yellow asterix for the network. No problem, reset both cable modem, and router and still no avail. I can connect to the newtwork, both laptop and smart phone but not browse the internet. So I then just updated the firmware for the router. I left the network open; this seems to fix the problem with the smart phones but not my laptop. All the other laptops work just fine, nobody has an issue. I am running an HP Pavilion DV4 with windows 7. Funny thing is, if I set the network up on my computer, with an account name and password, I can still log onto the network with my smart phone, but not browse the net. I have to do a hard reset, and keep the network open for it to work on my smartphone. Here is picture of the wireless details. I have run my Antivirus and Malware, and havent found any issues. I have also tried resetting the TCP/Ip stack with cmd>netsh int ip reset reset.log> netsh winsock reset catalog, to no avail and have tried using WinsockFix Utility to no avail as well. I am at a lost for words. My computer connects to wifi outside my house no problem, such as right now at work or at school. Any help would be greatly appreciated.
