I installed xubuntu on a new Thinkpad the other day, and can connect to my dual band home router (Netgear R7000) fine (both 5g and standard), but the connection drops every few minutes. I've gotten by reconnecting to my network manually, but it's annoying and I'd like to not have to do that. I mostly don't know where to start, having tried a few other solutions here or elsewhere to no avail. Any direction would be much appreciated!

Things I've tried:
- Setting a BSSID in Network Manager
- Adding
wifi.scan-rand-mac-address=no
to/etc/NetworkManager/NetworkManager.conf
- Disabling ipv6 in
/etc/sysctl.conf
with:net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1
Update 1 - Still having difficulty after trying @chili555 's suggestions(thanks!). I tried the following and made sure to reboot after each step.
- Turned off power saving in network manager and tlp
- set REGDOMAIN=US in /etc/default/crda
- removed spaces from SSID
- stopped using the 5GHz 802.11a/n/ac network in favor of the 2.4GHz b/g/n one
- turned off 20/40hz coexistence in my router settings changed channel from auto to 1
- set wifi security to WPA2-PSK [AES].
Would Mbps mode affect me? As of now it's Up to 600 Mbps and Up to 1733 Mbps for the 2.4/5g networks respectively.
Update 2 - Tried a fresh 17.10 install and had the same issues, so I can only assume it's a driver issue or router issue.
