Have any of you heard of the TCP Congestion Control bbr and how it is the congestion control to solve bottlenecks on Linux based systems? Maybe one of you whom is an expert svn ticket maker can request this to be implemented.
Ya, Broadcom ARM drivers are linked with k4.4. Plus, last I knew, the k4.9 Atheros/Qualcomm stuff runs pretty badly on DD; Kong reverted to k3.18 for it. You could try OpenWRT, but lose 5 GHz. Assuming it's supported at all...

It's like asking if an old proprietary Packard Bell desktop with a pentium 120 x86 will run a 4.14.x kernel. Depends on who you ask.
The trick is getting the proprietary Broadcom drivers to work with a modern kernel, and with the rest of DD-WRT, the latter is probably the more tricky part.

Don't run badly at all --- just have pretty bad latency issues for folks 100+ speed connections.
I'm still just 50/50 fiber so I don't have bad bufferbloat.
Most seem to recommend the R7800, but it is more expensive. The WRT32X looks nice, but just be sure to research the device and build threads for it. _________________ #NAT/SFE/CTF: limited speed w/ DD#Repeater issues#DD-WRT info: FAQ, Builds, Types, Modes, Changes, Demo#
