Yes, I saw some issues with rebooting on 3.7.4.2 RC3, too.
The other thing I noticed is that you cannot adjust the SNR anymore (eg 'adsl snr 15'), which previously stabilised the line on a poor adsl modem code (separate issue to UPNP).

Thanks Guys

We've been having problems since upgrading firmware to 3.7.4.1 We run a number of iPads, MacBooks, iPhones & Samsung Galaxay S4 in the house and they were all stalling periodically. Since changing the arp to 600 seconds, they all seem to be behaving.

The problem only occurred after upgrading from 3.7.3.3

Has anyone resolved the issue by downgrading back to 3.7.3.3?

Where did you change it to 600?

using the Ip arp command
