What is the current best hardware platform for pcWRT in terms of full feature set and best performance? Are there any significant differences between the pcWRT hardware vs the Archer C7 vs WRT1900ACS? Do the C7 and WRT1900ACS offer all the pcWRT features if using the premium firmware?
What would be good for additional access points (wired)?
Features are the same across all hardware when running the premium firmware. Generally speaking, WRT1900ACS is faster than the Newifi-D2 we had earlier, which in turn is faster than the C7. Our new WiFi 6 router seemed to have better WiFi performance than the WRT1900ACS.
If you want to connect wired access points, then WRT1900ACS and our new WiFi 6 routers are better choices.
