My Dell M3800's network card (Intel AC-7620) will not keep a connection. I used to be able to right-click on the wireless icon when I had the yellow warning and choose "Troubleshoot" and it would say it needed to reset the card and it would and everything was great. Now it will not reset the card, I have to manually restart the system, and it happens about 15-20 times a day. Very annoying.
Everything I have tried to fix the problem has not fixed it.
I would like to replace it with another card in hopes that I won't have this problem anymore.
Is the Killer AC-1525+ the one to go with?
Thanks

Don’t get Killer branded cards regardless of Intel or Qualcomm. They are nothing more than a QoS software suite. It has caused quite a few people headaches to the point where they only install the Intel/Qualcomm drivers. The 1535/1435 is a rebranded Qualcomm QCA6174A, the 1525 is a QCA6174 (minus the A) and the 1550 is an Intel 9260ac. Just buy the original manufacturer cards if cheaper as they are exactly the same.
I personally never had an Issue with Intel cards but if you are you can try Broadcom (ie Dell 1820A/1830) or Qualcomm cards as an alternative. The Qualcomm QCA6174A from what I have heard has had better drivers recently and after turning roaming aggressiveness to minimum you shouldn’t have any issues. The Intel 8265/9265 are also pretty good, most of the Latitudes/Precisions in the corp where my father works use the 7265/8260/8265. Also note that various AP, laptop characteristics and antenna layout can make one card better than the other based on the setup, so if you can try different ones and see which works best in your setup.
Also if you want a 3 antenna card, Broadcom is your only route, the Dell 1830 WiFi card is a good example of one. You will need to buy and place the third antenna to fully utilize its capability obviously.Last edited: May 17, 2018downloads likes this. -
I have heard nothing but good things about the Killer 1525 but the later versions have serious problems maintaining the connection speed.

Looking at Amazon, can I replace it with a Killer 1550 or Intel 9260 or 8260..?
They all seem to fit my slot and only have two antenna sockets -

When installing the new card the OS may not recognize it until the driver is installed.
While wireless card installation is for the most part plug and play but to get the best performance some tweaking may be necessary.
These new cards are W10 x64 only.
All cards do not work the same with all routers and location of the pc and router is critical for better performance.
My 9260 and 1550 work well with a Netgear R7800 router using 5ghz band on channel 48.Channel 36 has worked well also yielding a theoretical data rate of 1,733.30 Mbps most of the time. -
I do believe my wifi card is a NGFF, I will check that to make sure
My router is a Netgear R6300v2
I usually sit directly under it.
I don't know anything about channels..?
Thank you for helping, I have reset my 7260 over 3000 times (yes!) I really want this solved -
I have both a Killer 1525, and an Intel 8260ac.
The killer connects always at 300Mbps(only have wireless N..), the Intel, with 2 walls was at less than 100Mbps, and dropped connections a lot(as I was already expecting), they always do that unless streaming mode and the scanwhileconnected var is disabled on regedit(or as someone on this forum showed me, using the WiFi Optimizer that takes care of that automatically).
I always had connection "stutters" with Intel cards before changing those words on regedit, I dont understand how they never fixed/changed it.
Dell M3800: Intel AC-7620 to Killer AC-1525+ ?
