TP-Link TL-WN781ND WLAN PCI-E Adapter (150Mbits/s, Windows 8.x / Vista / 7 / XP)

Very good wireless card. Very eat to install. I have a system that has moderate specifications and runs both Ubuntu Linux and Windows 7. I put the card into my machine, very easy to do. Turned on my machine and to my amazement, without me doing anything the wireless card worked immediately in Windows 7. The signal strength was strong and after a few weeks of use it has never dropped signal strength or dropped the signal at all. I then booted into Ubuntu Linux (64-bit edition) and incredibly Ubuntu recognized the card and picked up the wireless signal as soon as it had started! Incredible! Again in Linux the signal always remains very strong and never drops. To confirm this product has worked excellently for me for about 4 weeks now in both 64-bit Windows 7 and 64-Bit Linux Ubuntu 11.10. It worked straight out of the both with no human intervention (installing drivers or anything). The card is very discreet. It picks up the signal strength very well, never dipping below 80% (in comparison my laptop with built in wireless in the same room never goes above 50%) and the signal has never dropped, being continously constant through many long-haul usages of the computer (between 12-20 hour uses). I cannot recommend this product highly enough.

This adapter is pretty darn fantastic. It worked straight away. Just bought a new computer, installed Windows, plugged this PCI card in, and boom. It worked straight away, no hassle or anything. Generally, with stuff like this if people say they can't get it to work, it's either a problem with their computer or a problem with them. If you know what you're doing, this thing will work immediately. Just put the CD in, it installs the drivers, and you have wireless internet. My only problem is one to do with range. I only ever get 3 bars, but only because I'm pretty far away from the router, say 15m ish. And I hate not seeing 5 bars on the corner of the screen. Consequently, I hide the network status icon, and I'm happy again, still getting optimum speeds - the apparent "connection status" doesn't really affect the speed - not really for me anyway. If you want a nice, quick, simple way of getting wireless internet on your PC, and you have a spare PCI-E x1 slot, get this. There's really no point spending loads of money on something which won't do a better job. This was very reasonably priced, comes with nice instructions and everything A great product!

I knew I should have spent more on something like this, but I went and purchased this anyway, stupidly trying to ignore the bad reviews somewhat. I'm running Windows 7 64 bit and this card didn't work for me. I got multiple blue screens and when my pc wasn't blue screened the performance was erratic to say the least. I couldn't get more than a poor signal in windows, where as my Macbook Pro gets an excellent signal. It would often not even connect to my router (Sky Broadband). Using Speedtest.net to test my internet speed I could only manage 1.3MB\s, where I would normally get 7.5MB/s through my Macbook Pro with an Ethernet cable. I tried the various drivers from Atheros and even tried the TP-Link ones as a last resort. I also tried to find some third party firmware but I didn't think it would be worth the potential voided warranty. I also tried changing the channel on my router but that didn't help, and why would it? Other wireless devices work great (phones, laptops, other PCs). Anyway, after all of the various fixes suggested on here (drivers, different PCI-e slot, etc) I could not get this to work properly. Perhaps I'm just unlucky, or maybe it is to do with the revision of the card itself. Mine was Rev 1.0, I believe there is a Rev 2.0 which might be what the people who have had luck with this card received. I don't hold anything against TP-Link because their other products seem to be good quality (from reading reviews on the higher up models). However, I think they may have skimped on something with this one. Quality control, drivers, I don't know, but there are definitely two groups of people who receive this card: those who receive good performance and others who do not. Despite all of this I was very pleased with Amazon's service as they dispatched and delivered it very quickly. I have also gone through the pain free process of returning this and will post it today. I instantly received my refund (through a gift certificate, you can choose money or gift certificate) and will put it towards a better quality wireless card which I should have done in the first place. If you're not running Windows 7 64 bit it may be worth purchasing as it's cheap, but keep in mind that there's a chance it won't work for you.

So simple,even I could fit this and get it running on my old desktop tower. Just followed the instructions,being careful not to touch the circuitry and it installed using the provided disk. You must tell the Computer not to install it automatically. Otherwise...an absolute doddle. It was ordered along with a separate antenna,which has not arrived yet (different seller). It still picks up a dozen local routers and compares favourably to the old HP Laptop Wireless operation that I also use. The price was incredibly low,in fact it was the cheapest I could find. Does all I need to use the Internet. Has the ability to connect me to another ISP when my regular goes down for maintenance and suchlike.It is also switchable (on the fly) without having to restart.

linux mint 22.3 ile sorunsuz biçimde tak çalıştır kullanma imkanım oldu. tabii 150mbps bugün için yeterli bir hız mı tartışılır ama pek çok evde internetin hala bu hıza ulaşamadığını düşünürsek fiyatının hakkını verdiğini düşünüyorum.

Very reliable and easy to install

Cheap, quick and was here next day. The card did its job and an improvement over the USB wifi adaptor i had

Sinceramente me estoy haciendo adicto a los productos de Tp-Link, ya había comprado una antena de 8dB de la que estaba muy contento pero la tarjeta WiFi sobre la que la usaba da bastantes problemas en Linux y me decidí a buscar otra. De paso que cambiaba buscaba una WiFi N, barato e interna y después de evaluar otros productos con doble antena y 300Mbps me decanté por esta, pues ya tenía la antena externa y tampoco necesitaba lo más de lo más. También buscaba que funcionara 'out of the box' en linux y para eso tenía que asegurarme que llevaba chip Atheros. Y ya de paso me propuse estrenar el PCI-e 1x que tenía mi placa y que lleva muerto de risa 4 años, además es la ranura que más alejada quedaba de otras tarjetas y favorecía el paso de aire para refrigeración. Esta tarjeta me costó 11,48 el 2 de Abril de 2012 (vendida por Amazon), me llegó muy rápido y cumplió todas mis expectativas. Para empezar la presentación es excelente, viene en una caja precintada, y dentro lleva la garantía, las instrucciones y algunos folletos con otros productos de la firma. La tarjeta en sí viene en la clásica bolsa antiestática con un precinto y me sorprendió lo minúscula que és, la antena es más grande que la propia tarjeta :-D. Encajó perfectamente a la primera y le enganché la antena grande que ya tenía, desenroscando la que venía con la tarjeta. Linux Mandriva 2010.2 la detectó sin mayores problemas, no hubo que hacer nada, configuré la Mac en el router (tengo filtro mac) y encontró mi red enseguida conectándose a ella sin mayores problemas. La llevo testeando 36 horas y sinceramente va de maravilla, velocidad estupenda y estabilidad de momento a prueba de bombas. Se me acabaron las inestabilidades y las transferencias son fiables y rápidas. Recomendada al 100%.

Ottimo rapporto qualità prezzo. Nonostante non sia veloce come lempou recenti è facilissima da installare con doppia piastra in dotazione per adattarla a PC normali o slim, funziona perfettamente e vieni subito riconosciuta sia da Windows che da Linux.
