Summary: I wish there were some way to know the version and chipset of wireless adapters before purchasing. It's very frustrating and time wasting to expect a certain radio and get junk.
Cons: Bought this at another store thinking it was an Atheros chipset. Turns out version 4 switched to a cheap Realtek RTL8192CU chipset. The speed is unacceptably slow 3.94 Mbits/sec on Linux kernel 3.12 measured with iperf. Binary drivers are not a solution for Linux. Look elsewhere and get an adapter with a good radio.
Summary: We have been using this for the past year or so, for my sister s computer and I have to say the wi fi is awfully slow on it.. The distance is about 10m away, but other laptops have better reception in her room than her desktop.
Summary: i do not know if there is a fix for this problem i have the version 2.8 drivers does not work with my computer . it is a hassle to replug after every shutdown i have other tp-link product for my XP and it works great.. just no luck with win7 ultimate 64bit ** i give this device 1/5 stars because there is no way to find the order id on the receipt to write a review for 1&2 stars
Pros: this device works , great signal
Cons: this device did not properly install on win7 64bit, this device did not reconnect after shutdown, this device require to replug into computer after every shut down
Summary: Stays connected but is really slow when useing with different name brands I'm using netgear as my main and for some reason the wireless adaptor is running at a speed of 54 which it says it sould be able run faster!
