Re: "Ive dealt with this nightmare on Dell laptops..." - qudjzjsuxx is totally right about those adapter properties. They fix the vast majority of these intermittent dropouts by keeping the card from constantly hunting for a new signal. Late to the party here but I would suggest also checking your BIOS version. Dell is notorious for having power management bugs in their firmware that mess with the wireless card's pcie link state. Just be careful when you update it tho... make sure your laptop is plugged into the wall and dont touch anything until its totally finished. If the battery dies during a bios flash, youre gonna have a expensive paperweight on your hands. Honestly, if those software tweaks dont work, the hardware itself might be failing. Some of those older Dell models used cards that were just flaky from the factory. You might want to consider trying a cheap USB wifi dongle for a day. If the USB one stays connected, you know for sure the internal card is the problem. Also, try turning off bluetooth for a bit... sometimes the antennas in these laptops are so close together that they cause massive interference when both are active.

Building on the earlier suggestion, I eventually got tired of the software side of things... I spent way too many hours messing with settings on my old Dell until I just gave up and went the hardware route. Honestly, it was the best choice I ever made for my sanity. I ended up just grabbing a cheap USB adapter from TP-Link and I have been super satisfied since then. It works well and I havent had a single drop in months, seriously no complaints at all. It is way cheaper than trying to source a replacement internal card or losing more hair over driver versions tbh. Just get any of those little USB Wi-Fi sticks from TP-Link and you will be set. Its a cheap fix that saved me so much frustration. Sometimes the internal hardware just hates Windows 10 and it isnt worth the fight... better to just bypass the whole mess.

Ive dealt with this nightmare on Dell laptops more times than I care to count. Since you already did the basic power management stuff, here are the direct fixes that actually worked for me over the years:

• Go into the adapter advanced properties and set Roaming Aggressiveness to Lowest. It stops the card from constantly hunting for a new signal and dropping your current one.
• Look for MIMO Power Save Mode and change it to No SMPS. This is a huge one for stability on Windows 10, especially with Intel cards.
• If you have Killer Wireless software or Dell ProSet tools, uninstall the apps and just keep the bare drivers. That bloatware causes way more drops than it solves, seriously.
• If all that fails, just spend the 20 bucks and buy an Intel AX210 card. Ive swapped dozens of these and it fixes hardware-level flakeyness instantly. Sometimes the hardware Dell ships is just junk and no amount of tweaking saves it... but those settings usually do the trick.
