Hi,

My R7 was working perfectly, I dont know what happened 2 days ago, it now refuse to connect to 5GHZ and when connected to 2ghz it is slow as turtle. I rebooted sevral time router and modem, and computer, i downloaded Broadcom driver from Acer site for windows 8.1 64 and still same issue.

Everything working perfectly on other devices, so it is jsut my acer laptop.

What had happend all was working fine now why my wifi all of sudden no more working after 3 months ? I hevnt installed any app for more then a month now, my anti virus is uptodate.

What should I do to solve this ? I am pulling my hairs off.

Also as some genius form Acer thougth it is useles to put an ethernet port on this laptop which should be universal on all laptops, now i cant even test with cable

Please help

Thanks

USB port on the left side,is software based ethernet port. Your modem package from ISP may have that cable . Did you try resetting your wifi modem (set a new password) you may have download malware that targets wifi SIND. hope this helps

Download inSSIDer version 3 (Google it; v3 is freeware, and v4 is not) and see what the signal strengths look like. If it's reporting a very weak signal, then there's likely a physical problem (if you're lucky, it's just a loose antenna connector; or worse if you're not). If the signal strength looks fine, then there may either be a software problem or a problem with the WiFi chip itself. A good way to rule out software problems (in general, not just in this case) is to boot your system with a Linux Live DVD or Live USB (not because it's Linux, but because it's a quick and easy way to simulate what would happen if you wiped and reinstalled your system from scratch) and see if the problem exists there--if it does, then it's hardware, and if it doesn't, then it's software/OS/drivers.
