I hope someone can point me at a few things what might help me with some network stability issues I seem to be having.
I'm running Asuswrt-Merln version 386.3_2 on the router.
Firstly, DNS.
I've been getting a few issues with web pages taking a long time to load, or failing completely. This used to be OK, but recently I often get an error page stating 'DNS_PROBE_STARTED', which then gets replaced with the page I was trying to see. Once I'm on a web site, pages load pretty quickly. So I think the problem is that DNS requests are taking are unpredictably slow, and sometimes timing out. The problem seems to be reduced if I manually configure the PC to use remote DNS servers (namely 8.8.8.8) directly, rather than going through the router.
Are there any known DNS issues with Asuswrt-Merlin on this router?
If not, what are sensible DNS settings to choose on the 'WAN - Internet Connection' tab, namely DNS rebind protection, DNSSEC support, etc?
The second issue is that my Sky box frequently fails to connect to the network. Probably related to this, I'm running a Fingbox on my network which often reports that DHCP isn't healthy. So...are there any known DHCP issues with the firmware/router?
I should probably also confess that my router is actually sitting behind another router/DSL modem supplied my by ISP so I have 2 levels of NAT, but the other router is configured such that all traffic is forwarded to the ASUS, which is set as an 'exposed host' (DMZ), and DHCP is turned off. This configuration seems to be generally working well (and I can check DSL line performance, etc), and I'm not sure it will have any effect on the DNS/DHCP issues I'm having.
Cheers!
