I have installed Elementary OS on my Thinkpad T540p with Intel Wireless Dual-Band AC-7260 however its constantly dropping after using it for a few mins and I cannot just figure out what I can do to fix it. I looked around the internet and messed with some files but it hasnt helped. In Windows I did have this issue but I fixed it by reverting the drivers to a old version. What can I do to fix it? Otherwise the OS works great

ran lspci -nnk | grep 0280 -A2 command from terminal

zahid@zahid-ThinkPad-T540p:/$ lspci -nnk | grep 0280 -A2 04:00.0 Network controller [0280]: Intel Corporation Wireless 7260 [8086:08b2] (rev 83) Subsystem: Intel Corporation Dual Band Wireless-AC 7260 [8086:c270] Kernel driver in use: iwlwifi

I think it runs fine on 2.4Ghz networks but as soon as I switch to 5Ghz it starts dropping and basically crashes
