Recently, I purchased a new Dell Inspiron 15 (3537) – however one of the worst things about this laptop was the fact it only had a 2.4GHz wireless card. While my first change to this system was to replace the 750Gb hard drive with a 256Gb SSD – to get a massive performance boost, the slow wireless was a killer. To make matters worse, the wireless card was also tied into the bluetooth adapter.

After a bit of hunting around, I found that the Intel AC-7260 was a PCIe Half Mini Card with bluetooth onboard. This would make it a drop in replacement for the card that Dell shipped with the laptop. It would also allow me to connect at the full 300Mbit speeds of my WD MyNet N750.

I ordered the card and it arrived quickly, but I soon started to find issues with this card. The main one being that randomly fails to work properly when the laptop resumes from sleep.

When I did some searching about this problem, I was very surprised to find that this and many other problems seem to plague this range of card from Intel. There are threads on whirlpool, and multiple threads on the Intel Communities support site.

This seems to be either a hardware problem that Intel refuse to admit (as they’d have to replace all these cards with OEMs), or a driver problem – either way, it seems to have been ongoing for over a year.

I specifically bought an Intel wifi card thinking that a big name like Intel would make a decent wireless card – but it seems that I was mistaken 🙁
