I have an issue, and I hope you all can help. I recently purchased a Netgear WNDR3700 router (v4) and flashed the router with DD-WRT firmware (the router is very new so the only firmware available is still in 'pre-release'. For the most part, everything has been working great.
However, I am having a very weird DNS/ping issue on my local network. Basically, the connectivity between the various connected devices is intermittent, when it comes to accessing by host name. For example:
1) Pinging PC 2 from PC 1 (using host name) returns valid correct result
2) Pinging PC 1 from PC 2 (using host name) sometimes returns 'host not found', and sometimes it just starts working
3) I have a server running Windows Hyper-V 2012 (Core) with 1 VM installed. From any machine on the network, I can ping the VM (Guest) just fine using hostname, but no machine on the network can ping the Hyper-V host by hostname. Including the guest.. the Guest OS cannot ping its Host, it says Host not found...
I can ping all machines by IP address just fine, it's the hostnames that are not working 100%.
Sometimes, however, if I try and ping the Hyper-V host over and over again, sometimes after the Nth time (usually 5-6th), the Ping returns back with the proper response. And then after about 15 minutes, it goes back to "host not found".
When I use NSLookup {hostname}, it correctly returns back the correct result. It's strictly ping that is not working.
I thought it may be due to the way DD-WRT is handling DNS... any ideas?
This is driving me insane.. any help would be greatly appreciated. Thanks in advance.
