I have the same system described many times with same problem with W-Fi dropping connection constantly.
Broadcom Network adapter. E1-571. Windows 8. Up to date drivers and BIOS.
I have constant problems staying connected to the internet too. First it would drop and then not connect without a restart. I contacted Acer and they said to upgrade the BIOS to V. 2.15 - latest on their website. This seemed to help.. but still would drop occasionally with power chord in on Wi-FI, and almost never stay connected with power chord out. (perhaps the power chord acts as an antenna, perhaps the computer is just designed badly and when not under battery power will not stay connected via wi-fi, who knows)
Wireless drivers a few minor versions newer than onsite - came installed.
Nothing seems to work to keep Wi-FI connected.
Since buying the computer without doing good research (sigh).. the last thing Acer emailed me was to setup arrangements to mail them my computer - but they didn't say how much they would charge me to fix it. Assuming they had a fix.. which they didn't say they had. I'm not sure about sending them my computer.
I think the computer is just a bad crappy machine. Acer has already discontinued it.. no longer makes it..
That fact says it all.
Has anyone found any solution to this problem?
Has anyone had Acer successfully fix this computer for them?
Anyone found ANYTHING? Please share if you have..
Thank you - would be much appreciated.
