Question: Is this compatible with the HP Pavilion dm4-1265dx? It uses the half sized card but a different one I ordered is not compatible.
Document: As a linux user i have tried many different wifi usb adapters and pcie chips but this one actually works perfectly, I highly recommend this card to anyone that uses linux.Tested on OpenSuse 12.3.
Bought this item to replace a suddenly dead Atheros 9285 WiFi card in a Toshiba C655. This is a half-size WLAN card, make sure you know what you're ordering. I ordered another card from another vendor and it was a full size mini lan card. This one is about the size of a half dollar coin, the "full size" was about 50% larger and would not fit my laptop.This one arrived quickly, at a good price.
Performance improved greatly over the Atheros OEM junk. Download the full suite of intel drivers prior to installation to make life easier. Make sure you get the half height mini-pcie where needed, I almost ordered a full-height card in error.
So i bought this card because i had a crappy qualcomm atheros something or another that didn't have dual band capabilities which came with my customized HP Pavilion g6 laptop, and the wireless card was the only thing you couldn't customize on HP's site.
The card wasn't recognized by the HP laptop. Not sure if it is a HP thing (bios) or the card itself is defective. Either way was a bust.
The 5100 half size mini pcie card arrived 10 days ahead of schedule. I had watched youtube videos on how to install it in my dell 1550 laptop and in fifteen minutes I had the card installed. After I placed my log in password to my router, my wi-fi was working perfectly again. I am completely satisfied with the product!
I have a Sandy Bridge-based laptop that uses another Intel wireless card that has serious stability issues with EAP networks. Most of the time the connection gets dropped or has little-to-no throughput. By significant contrast, this card works flawlessly and has decent throughput.For Linux users with EAP-enabled networks, I HIGHLY RECOMMEND THIS CARD.
Arrived early and works as described. Anybody needing a new Wifi card, I would recommend this one wholeheartedly. Thanks AMZNeTek for the awesome product, keep up the good work.
These cards are great for migrating all the laptops in your house over to the 5.0ghz band. I have a pair of wireless headphones that operate on the 2.4ghz band and I was tired of them being interfered with, so I bought one of these and tried it out. It really does a great job compared to the old 802.11g card I had previously (also an intel, just slow, outdated and interfering with my headphones).
Tried an Intel 6100 card, first and discovered, like so many others, that those will lock up your Dell laptop when you max out your transfers. Picked this one up and it runs like a dream. Great replacement for the Dell 1397 802.11g adapter that comes with the Inspiron 1540. LAN Speed test says I get about 58mbps down and 61mbps up. Drivers were automatically loaded in Windows 7 Home Premium. Great experience so far.
Answer: Sorry Marc,  Cannot say-have never had an HP.   Suggest you check HP website or sites that sell upgrade wifi cards.  When you say 'not compatible', do you mean that the card does not physically fit, or that it fits but is not recognized by the laptop?   If latter, I would search online for the wifi card model number-you may need to install a new driver.  You could also search for 'upgrade from ' + your current wifi card model number to try to find wifi cards that are compatible with your laptop.  That should help regardless if your problem is physical fit or the card not being recognized.
