Okay so i have 4 computers hooked up to a d-link router and its all good untill today. I got home and well the main computer i use was able to go on any the internet or do anything it wanted online but the other 3... well they were stuck solo couldn't even do lan things. So i went to my router settings (192.168.0.1) and looked around there for anything that looked like it was changed but couldn't find anything and i look in the settings about every day to see how much bytes were sent/recieved in that day and to reset the count also so i have seen most of the settings many times. I couldn't find anything so i tried restarting my router manually by pushing and holding the restart button in for 10 secs while it was booting back up i started making dinner and went back to my comp around 5 mins later this time NONE of them could go on so first i tried going to my router settings again this time i could get on to the page but i couldn't click anything as when i did it would tell me i have little or no connectivity and thats all it would do so then i did a virus scan and there was none but i did have a few adware but it was things that i have seen before so it didnt bring much of a worry. Read in my router book that removing it from power should reset it so i tried that but now i cant even go into my router settings!!!! After all that i found the cd for my isp and used it so i could get 1 of the comps online to seek help as im totally clueless as what to try next. If you have any suggestions it'll be great. Edit: I also tried reinstalling my network card and that didnt work was the last thing i tried. Edit #2: I also tried ipconfig /release and ipconfig /renew in cmd and those dont work i can do the release but when i try to renew it, it just lags for awhile and then gives me.... "C:\>ipconfig /renew Windows IP Configuration An error occurred while renewing interface Local Area Connection : unable to contact your DHCP server. Request has times out."
