bought new asus router recently. have 3 laptops and a desktop hooked up no issues. bought lenova yoga211 laptop with window 8 and it says limited connectivity. worked fine for a while, then turned off for no reason and when it booted back up it won't connect to my router.
itll connect to other routers but not mine. did factory restore worked until i turned computer off and now it doesnt work anymore.
tried the above to see if it would fix things and everything failed. any suggestions? tried calling bestbuy/lenova and they all want 99$ to troubleshoot the issue
