DGL 4300 DNS not responding


A few months ago after a FW update 1.9 my power supply went on my DGL 4300, so I replaced it with a new one (same model number as oeiginal router adapter, official and all that), ever since then I've been randomly getting DNS timeouts, and after a while can't access the internet, a power cycle always seems to fix the problem forawhile, but it keeps happening. It seems to work fine when my modem is not connected, but as soon as I connect it, it occurs again. It's quite weird

Internet Service Provider and Modem Configurations

* What ISP Service do you have? Cable or DSL?
* What ISP Modem Mfr. and model # do you have?
* What ISP Modem service link speeds UP and Down do you have?
* Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values

* Enable Use Unicasting (compatibility for some ISP DHCP Servers) under Setup/Internet/Manual.
* Turn on DNS Relay under Setup/Networking. Link>Finding Faster DNS Addresses using Name Bench
* Setup DHCP reserved IP addresses for all devices ON the router. Setup/Networking. This ensures each devices gets its own IP address when turned on and connected, eliminates IP address conflicts and helps in troubleshooting.
* Ensure devices are set to auto obtain an IP address.
* If IPv6 is an option on the router, select Local Connection Only or Disable IPv6 options under Setup/IPv6.
