@ Emmanuel Not to sound pessimistic, but there seems to be a rather wild different between one 7260 to the next 7260. Myself and two co-workers got the same XPS 13 with Ubuntu. The other two had no issues, while I would disconnect continuously, often times even when we were in the same room. We were running the same distro and everything. Even when I swapped the card three times, antenna twice, and the motherboard once, the issue persisted. Ultimately this resulted in me trading up the XPS 13 under warranty for a Latitude E7440 with Ubuntu, so it worked out (for me) despite the issue not having been "fixed". Likewise, a friend of mine had a laptop with a 7260 chip where he had nothing but issues despite the extensive amount of troubleshooting and testing he did. He ended up buying another 7260 based laptop ready to swap the chip but he ended up having no issues, so he just kept chugging along with it.
There's a massive thread on the Intel forums with seemingly no answer. Users from all types of distributions and operating systems are posting about their issues, from 7 to 8 to Arch and Ubuntu. I want this fixed in ways I cannot begin to describe, but we're about 1.5 years in since this card's release with no "official" fix, just odds and ends tweaks that seem to help one or two users, but not everybody. I can't help but to feel that this is some sort of hardware issue. Unfortunately, Intel has been rather quiet about it, so at this point it's nothing more than an assumption. Anyway, just wanted to throw that out there. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-firmware in Ubuntu. https://bugs.launchpad.net/bugs/1293569 Title: iwlwifi-7260-8.ucode causes network disconnections problems Status in The Linux Mint Distribution: New Status in linux-firmware package in Ubuntu: Invalid Status in linux-firmware source package in Precise: Fix Released Status in linux-firmware source package in Trusty: Fix Released Bug description: Running 14.04 (beta) with Kernel 3.13.0-17-generic I've encountered a strange and reproducible error with the iwlwifi-7260-8.ucode firmware. This laptop is a Dell XPS 12 (haswell). With the -8 firmware, it will connect fine to wifi for 30 or 40 mins at a time, then will start dropping connections repeatedly. Even modprobe -r unloading and reloading doesn't fix the issue, only a reboot will temporarily solve it for 40 mins at a time. Moreover, here is what's strange, is during these episodes of disconnection it seems to affect the actual router (2Wire), as the other devices in the house will also start to have issues (very slow connections, limited range,etc). Once I reboot this laptop everything and all devices will return to normal. This issue has been fixed by me manually removing the -8 firware from /lib/firmware and letting the -7 firmware load instead. Since that has been done there has not been a single issue of this happening (now going on 4 days). let me know if there is any other information you would like me to provide.
