I have just upgraded one of my backbone links from RB532 to a PC based router. It is a link over 7.4KM using R52's either side. If I run 5.8 Turbo with Nstreme, Polling and Dynamic size I get incredible results - up to 75mbps on a tcp bandwidth test. The problem is the link is very unstable - it runs for anywhere from 30 minutes to a few hours before the PC freezes up completely. If I run 5.8 standard with no nstreme the link is rock solid.
Anyone experienced similar issues? I am running a 3ghz celeron on one side and a 600mhz celeron on the other. The 600 celeron is the machine giving the issues. I have tried changing pretty much everything except the CPU, Motherboard and CF. Both routers are running 2.9.44.
