I've not experienced that I have to say, although after a resync it can take a while for traffic to start flowing correctly.
I'm assuming you haven't had a resync around the same time Chrome throws the DNS_Probe_Finished_No_Internet error?
Also, who (or what) are you using for your DNS?
Cheers

No, no resync . For DNS I'm using the standard PlusNet ISP ones whic work fine with the PN Hub.
I've just had a little play with it but cannot switch over until tomorrow. I've set the ZyXel up as follows in advance of tomorrow:
1. Running firmware "1.00(AAKL.14)C0"
2. Backup of config taken
3. Performed factory reset
4. Installed firmware "1.00(AAKL.14)C0_20160408"
5. Performed factory reset
6. Restored backup config
I'm assuming the firmware in item 4 is slightly newer as it's date stamped. Overall file size was the same.
Previously, other routers, I've found the "factory resets" a good practice to follow when flashing firmware.
