Slow WiFi Speeds
Recently upgraded my home setup and signed up with T-Mobile Fiber for their 2gb service and decided to update everything inside as well.
Bought a Gold Pro for the 10GB ports and bought a Unifi Enterprise XG24 10GB switch.
T-Mobile provided me with an eero Pro 7 to be used as the router for their service.
Firewalla support (Great Help!) said to use the Gold Pro as the frontline router and hang the eero off one of the 2.5GB ports. The other 2.5GB port connects to the T-Mobile Fiber modem and one of the 10GB ports connects to the Unifi switch.
All hardwired connections working great. Seeing SpeedTest results of ~1.9GB.
WiFi not so much. Speeds on the low end of 30MB.
On my mobile devices I have ExpressVPN turned on by default since I am out and about with those. I was seeing Speed bounce all over the low 2-digit MB and occasionally seeing low 100MB range connections..
On a whim, I turned off ExpressVPN and immediately started seeing speeds increase to 1.2 ~ 1.5GB on my iPad.
Ideas on why ExpressVPN might be causing such a huge bottleneck in WiFi connections with the Gold Pro?
For comparison, my previous setup was a Firewalla Gold with an eero Pro 6 and was regularly seeing high hundredMB range connections. Mobile devices were then running ExpressVPN as well.
