I'm from Norway and i just bought my Acer Aspire V3-571g. I've had it for 6 days now, and the internet problems started on the secon day, when i used Acer Live Updater, after that my internet started becoming limited, and this is the only PC in our family with this problem. I installed the new driver from the Acer driver site, and i als turned the "Turn off wireless to save battery" option. I also tweaked the battery to use maximum capacity for the netwrok adapter.
All of this helped just a tiny bit, now i dont disconnect so often, but i still do. I can overlook the flaws with the touchpad, because this is a very good PC for a nice price. But it's impossible to do anything when you can't use wireless, and my LAN cables doesn't reach to my room. I tried using a USB adapter, this worked. So i have a temporarily fix.
I have the same problem. I have a WIFI connection with 40mb/s down and 5mb/s up. But i can not use all of this presius internet. Because i seem to be limited to about 0.8mb/s download. No limit on the upload.
If i connect a LAN cable I can bennefit from allmost 40mb/s.
I have tried to test the WIFI connection in my house. Both my iPhone and my brothers labtop has full wirreles connection, where my labtop only have 0.6mb/s.
Now here comes a stranger part; sometimes the block seems to drop and i get full WIFI speed. Then suddenly again, 0.6mb/s.
My wireless adapter is "Broadcom 802.11n" with the 220.127.116.11 driver installed.
