When I was about to throw the Huawei WS320 already almost out the window, because he let himself simply does not connect with the wireless router, I again read all the reviews here (in any forums was to find no reference): Lo and behold .. someone. Here, some reviews earlier the problem has debunked ... it is on the WLAN password. It must not contain special characters such as "$ &) (" etc. included. Possibly must the SSID, so the name of the wireless router also contain any special characters, but what I have not checked.
Actually, I would deduct a star that this important information is not mentioned in the instruction manual. But the price and performance are otherwise very good, I do not want to be more Catholic than the in Rome.
Great inexpensive device to increase performance and wireless radius enlargement!
