Good product, only a few small notes. (Impressive WIFI range!)

ByRogueon November 5, 2011

Verified Purchase

Pretty much the only 11n PCI mini-card you'll find on the common market... Normally I would consider this a bad thing. Probably still is. But the WN861 is quite impressive. Its wireless throughput seems solid though the old laptop I put it in is incapable of maxing it really. It's wireless range is INCREDIBLE. Easily twice that of a usb 11n stick... About 1.5x the 11n PCIe ASUS n11 card in my desktop! Yeah. that's range.
I didn't even replace the origial 11b wireless antanas in my computer for it. I can only imagine if I had with some higher gain ones.

Drivers on included CD are worthless. Don't use them. Ones of TPlinks VERY nice website however work perfectly. Knew this in advance, though I tested it out of curiosity.

There were 2 issues that while minor, need to be noted:

Firstly, this WIFI card draws a good bit of energy. Some laptops may not handle it. The little tiny Libretto L5 I put it in gets temperamental when the battery is low and the WiFi is in use. Then again its a VERY low power laptop(Pre-netbook ultralight circa 2003, Transmeta based). Not to mention old. Long as your systems internal voltage regulation isn't stressed... It should be fine.
Aka, avoid putting this in cheaply made low power systems. Or well, know the risk you are taking.

The second note is that the card's IRQ got assigned to the same as the GPU in my computer... Sadly in the case of Transmeta hardware this is nearly impossible to fix. This should be troubleshootable in most cases however on more normal AMD/Intel hardware via the bios one way or another.
But if you have bad performance, check this. Remember this thing IS PCI not PCIE, it still uses oldtype IRQs on many systems. Meaning IRQ conflicts... Well. Yeah. They happen.

Excellent Replacement Wi-Fi Adapter

ByJaycee2uon May 4, 2012

Verified Purchase

I replaced an existing WI-Fi Adapter (802.11a,b,g) on a ThinkPad T30 with the TL-WN861N IEEE 802.11n because I was experiencing frequent communication drops with Windows 7. In spite of my fruitless efforts finding a more compatible driver for existing card, I decided, based on reviews of this card, to purchase this as a replacement due to reasonable cost and that it offered 802.11n. I simply installed card, connected the two internal antenna wires and powered up Windows 7. It immediately discovered the hardware and installed the same drivers as found on the manufacturer's website. BTW, for those of you that have IBM ThinkPad laptops, you may need to apply the 1802 error fix. Google it for more information and follow the instructions. And yes, I am happy with this purchase.

Update 05/07/2012: This card also works well with Linux Ubuntu 10.04 on the ThinkPad T30. Card was automatically detected/configured without operator intervention.

Works good but...

ByAmazon Addicton May 19, 2012

Verified Purchase

I got this for my D600 and it works great but the driver is preventing my computer from coming out of standby. I'm in the process of trying to figure out a solution with tech support. This means every time I close the lid I've got to do a restart when I open it back up again. A major pain. Other then that, I'm very happy with the card and the speed between my devices.

Update
Tech Support never got back to me with a solution after three attempts to fix the standby issue. I ended up pulling the card out and putting in my old Intel G wireless. The annoyance of not coming out of standby ended up being more of a pain then the benefit of increase computer to computer speed. Overall internet surfing is pretty darn close.

TP-LINK TL-WN861N Wireless N Mini PCI

ByJim - Lansing MIon October 3, 2010

Verified Purchase

This product worked well in my Dell Inspiron laptop... note however, that the TL-WN861N only has two antenna connections, and the picture attached to this description incorrectly shows the TL-WN961N which requires three antenna connections. It appears that a number of the Amazon retailers have this incorrect picture (TL-WN961N) shown when they are describing/selling the TL-WN861N. If you need two antenna connections this (TL-WN861N) is the unit for you. If your PC has the option of connecting a third antenna for extended range you may wish to verify with the seller that you are getting the correct card.

good adapter, but be careful with the software upgrade

ByTONY DERRon March 20, 2015

Cheap,good adapter, but be careful with the software upgrade,get the right one or you will have strange problems with the adapter.
I have been using it in a laptop for a long time and so far have had no problems with it, I replaced an Intel adapter card with this one and WiFi range, signal strength,speed of connection have all been good and installed software works well.

Great wireless card - awesome range

ByB. Evanson December 28, 2009

Verified Purchase

I bought this for an old Toshiba laptop that needed a wirelss card. The range is incredible, & way more than I would have expected for twice the price. I paid less than $19 + s&h. I will definitely be looking for this card next time I need one.
