internet disconnects from router

[bikehuman]

No problems until I tried to change my LINKSYS router from unsecured to WPA. Problem was I could not connect my Lexmark 6700 printer to router. I have gone back to unsecured but now my PC/ internet will not talk to router. Everything worked fine 6 hours ago. I have plug the internet directly to PC and it works. I have reset my modem but that didn't help. I also cannot call up the IP address on internet to see my router.

I didin't find a Lexmark 6700 model listed. How are you connecting that to yor network? Is it wireless or wired? If it is wired, there should be no conflicts with the WPA settings.

Did you reset your computer's wireless network settings to NOT use WPA? The command below will generate a text file that shows your network settings. Post the contents here for analysis.

ipconfig /all > C:\ipdonfig,txt

make/model of the router would help.

I can't find a Lexmark 6700. Are you sure that's the right model? I'm assuming it is a wireless printer, since you're trying to connect it to the router.
