Thinking about buying this to replace an Archer C7 to have more CPU horsepower for VPN applications. But if the wireless is unusable, then I guess I'd just wait and see.
Or what would you recommend? Does anything more powerful than C7 have nice support?
Wireless is not bad on the C2600, its just unstable only at full load.
Eg I have one in my place, all my devices are connected with wireless and it works fine without crashes.
So someone one day asked about a router for office, so I suggested the C2600. Here's the thing, this guy has over 30 devices concurrently active, mixed 2.4 and 5Ghz. The wireless crashes non-stop for him and he keeps calling me..
The ISP provided box, which has a far less powerful CPU and much less RAM, works stable with the same workload (stock FW though, not OpenWrt/Lede).
The CPU on the C2600 can do about 500mbps of VPN traffic IIRC, the stats can actually be found here in this thread if you look through it..
And thats on the CPU, the SoC has HW acceleration but its not used.
The WRT series (eg WRT1900ACS) also has HW acceleration and a driver is available, people benched those at even higher speeds.. but wireless from what I hear is quite bad on those.
In conclusion, if you dont have a gazillion wireless devices, and your VPN speed is <= 500mbps, then the C2600 should serve you well.
