IntelNetwork 7260.HMWG WiFi Wireless-AC 7260 H/T Dual Band 2x2 AC+Bluetooth HMC

This was a great upgrade for my Qosmio laptop.I purchased the card on Amazon from A4-TRADE and had a disappointing experience with them on two fronts - first they apparently sent electronic shipping info but never actually shipped the product (so I had to contact them after several days to get them to actually ship it). When the item arrived it was in a standard (rather than an anti-static) plastic bag - an item like this should ALWAYS be shipped in anti-static packaging. I'd suggest checking with your chosen supplier before purchase that they will ship it in an anti-static bag. However, a supplier who doesn't use anti-static bags is also unlikely to use anti-static precautions when handling the board for shipping.No gripes at all with the device itself, speeds are fast and so far I haven't noticed any of the disconnection type issues some reviewers have complained about. I suspect their disconnection issues may actually be more to do with their routers rather than the device (reviews of some recent AC routers have many users complaining about daily or frequent disconnects). Anyway, worth getting the latest firmware for the router!To install in the Qosmio laptop was relatively easy, remove the subset of F6 screws from the underside that secure the keyboard (I forget if you have to remove the three screws from within the RAM / Hard drive compartment), slide out the DVD, pop out the keyboard (finger access to pop it out is from within the DVD space) to reveal the WiFi card slot. Take a lot of care with the ribbon cables and connectors - never pull or push the ribbon with force). It's worthwhile blowing out the dust from the CPU fans while you're at it - full details of removing the case can be found in various forums - recommend perhaps getting some experienced help if you're not familiar with flat ribbon connectors and micro-coax connectors.I did have a little trouble with the Intel driver installation (Windows 7 64-bit). When I installed the "software with drivers" the card did not appear in the Windows Device list, only after installing the "drivers only" then reinstalling "software with drivers" did the card appear but after that I have had no problems at all and I'm very happy with the upgrade.

I purchased this card in combination with the new ASUS RT-AC66U where I installed DD-WRT. I installed this card on my Lenovo V570 after removing the BIOS blacklist. The Lenovo V570 has two antennas so that worked well with this card. I downloaded the drivers from Intel and installed them on a Windows 7 x64. It works very well, so far I have not experienced any disconnects as other users have, maybe because I used the latest Intel driver. I have not tested bluetooth.I have configured my router for 80Mhz of bandwidth at 5Ghz 802.11ac and 40Mhz for 2.4Ghz. I have also checked the settings for the Intel AC 7260 and changed the following:- 802.11n Channel Width for 2.4Ghz: Auto- 802.11n Channel Width for 5.2Ghz: Auto- Preferred Band: 3. Prefer 5.2Ghz bandI also checked multiple channels for the 5Ghz interface. Some channels were pretty bad with connection speeds of 70mbit/sec.I have my router upstairs and use the laptop downstairs. The connection speed at 5GHz shows in DD-WRT and Windows at 585 mbit/sec. My old 802.11n card was connecting at 144 mbit/sec. After testing some file transfers, the effective bandwidth was around 15MB/sec, which is effectively around 120mbit/sec, 10 times the 1MB/sec that I was getting with the 802.11n. In theory I should be seeing transfers of 60-70 MB/sec but I am happy with my 10x improvement. Now if you are testing this card by transferring some files, your storage needs to be able to handle these transfer speeds. I have a 10TB storage array connected to my server via 4Gigabit Fibrechannel that can do more than 300MB/sec (limited by the 1gbit/sec network connection of the router to 120MB/sec) and I use an Intel last generation flash SLC drive on my laptop that will easily do 100MB/sec, so my backend storage can support true 1 gigabit/sec.One last thing, be aware that the seller SPICY BOMB is selling fake cards. These cards are Atheros AR9462/AR5BWB222 with a photocopied sticker from an Intel card. These are not even AC wireless cards. If you purchased this card from SPICY BOMB, please look at the sticker and see if you have WFM: 0C8BFD2C745A and BDM: 0C8BFD2C745E. If you do, you have the fake card. You can also identify the fake because the antenna connectors are marked CH0 and CH1 instead of 1 and 2 like the Intel.

I bought this adapter because it had a chance to use the high quality APTx bluetooth codec, and I was happy when it worked. I installed it in an Asus V551LB laptop, and after installing the Intel drivers, the wifi and bluetooth were working perfectly. I had a chat with Intel support, and they said that technically, APTx is not supported on on devices that didn't come with this adapter installed (and they're right: the APTx logo is supposed to appear when a device that supports it connects, but nothing happened when I paired my APTx headphones,) but there is definitely some high quality streaming going on here.I compared several songs, listening through my APTx headset, on both my laptop and my phone (which does NOT have the APTx codec,) and the difference is audibly clear. On the phone, the compression is noticeable, with the high frequencies all scratchy and warble-y. The same song on my laptop (with this adapter) has no issues like that (since the APTx codec ups the bitrate to 192kbps, which for most people, is practically to lossless quality.)As far as the wifi features are concerned, they are d just as good as any other adapter. I can see both signals from my dual-band router, and can connect to each easily. I am getting connection drops occasionally, but I'll be going to check the broadcast channels soon to see if there is any interference. I also like the Intel Smart Connect program that is available (when you put the laptop to sleep it wakes it up every 15, 30, or 60 minutes to update your email and social media programs, then put the computer back to sleep,) it makes it so I always know if I have any updates after putting the laptop to rest for a while.

I installed it into my laptop to replace the old WiFi adaptor that just didn't cut it, the old adaptor was extremely slow and the range wasn't as good, when I replacoit with this one it's a night and day difference, in speed and range.

As expected.. It's Intel.. what can I say..
