Sorry to bring this thread back up. Sadly I have to use the ISP provided router for now, there is no option to disable the key exchange time. The OS2 is the only device that suffers and it is starting to get very annoying, I will be talking and I just drop out, struggling at the moment to have a qso with anyone where it does not drop out. This only started happening after a firmware change a while back so can this issue be looked into?
