Hi @all,

My Acer V 15 Nitro keeps crashing the router and modem in the span of a few minutes to several hours (such that, obviously, the connection of any other device that is using this router will be compromised), after which I have to reset both the router and the modem to get them working again. After reconnecting my laptop, the whole cycle begins again and some days I find myself resetting the router tens of times and not being able to get any work done.

I know for a fact the problem lies within the combination of laptop-router as:

• the router does not crash when any other devices connect to it (Phones, laptops, pcs), only when the Acer laptop connects
• the laptop does not crash any other routers or hotspot connections (connecting to a cafe's WiFi or to my phone's hotspot works just fine)
• when connecting laptop through ethernet, internet works fine

I have tried:

• updating both the router and the laptop to the latest drivers/ firmwares
• reinstalling the drivers
• reinstalling the network adapter, using static ip address
• unchecking the checkbox for "Allow computer to turn off this device to save power" setting from Device Manager -> Network adapters -> Qualcom Atheros
• changing the Wireless Mode
• changing Roaming aggressiveness
• changing the Preferred band
• resetting router to factory-default settings
• replacing the router altogether
• changing the network profile from private to public
• turning off "Use random address for this network"
• asking the ISP for help (they were of no use, though they tried their best)

Some days the connection works just fine and no crashes take place, but when I try to upload large amounts of data (500 Mb - 2 Gb) the router will definitely crash. More precisely, whenever I try to upload photos with WeTransfer; Crashes have also happened when I try to watch movies or even when opening multiple tabs in a short period of time.

I've read that my laptop could be making my router think that it is under a DDos attack. Is that a possibility?

Another thing I've read is that the Qualcom Atheros network adapter could be a bad match with the Archer C7. If that is the case, what solution would you recommend?

I honestly don't know what else to try besides maybe reinstalling windows (I have Windows 10 and it is currently up to date) or getting a new laptop. I've read countless forums with similar problems and none of the suggested solutions worked for me. Any help would be greatly appreciated!
