Problem when PC comes out of standby.

    I have recently flashed a WRT54GS v4.0 with Tomato 1.15 and love it. I noticed that when my PC (MSI-K8N motherboard) comes out of standby after a long period of time (Several hours) I have to wait an excessive time before I can get through to a web site. I did not have this problem with the latest Linksys Firmware on it and was wondering what I can do to troubleshoot this further. I have several devices set for Static DHCP and have some port forwarding/mapping set up which works well to allow access to some internal network devices.

    When I have this problem I simply wake up the PC and open IE once the network connected pop up occurs. I cant get to the web but I can immediately open another browser session and get to the router's IP and see the web config screens.

    I see others are having success with the latest release so I'm thinking there is something up with my setup. Remember the linksys firmware did not have this problem.

    I have cleared the NVRAM after the 1st "lockup" and reconfigured everything manually.

    I tried looking at the logs but they don't seem to provide any error's or valuable information as far as I can tell. I can post the log if needed.

    I am not using any wireless devices and the wireless is disabled.

    Any input is greatly appreciated.

    Shot in the dark: Once the "Network Connected" pops up, immediately go to a DOS prompt and renew your DHCP lease:

    ipconfig -renew <LAN Connection Name>

    Then try to access that web site.

    What I found was that Windows sometimes screws up the gateway assignment from DHCP after a wake-up, especially when you have 2 or more gateways. Some recent Windows "security patches" seem to exacerbate this problem.

    I tried some troubleshooting and found something interesting. I found that it was related to ZoneAlarm, my software firewall. I found that when the PC would not access the internet I could shutdown the firewall and immediately it would work. I cleared all of the programs in ZoneAlarm and reset which ones get access by default and this still did not fix the problem. Finally I found a setting under the Firewall>Main>Advanced that says "Allow Outgoing DNS/DHCP in internet Zone on High Setting" and checked it.

    So far so good. No problems accessing the internet out of standby.

    Thanks for your help.

    Cool. Note that, if you access the internet via your router, you don't really need a firewall on your PC - your router does the firewalling.

    (Don't confuse with anti-virus software - you still need anti-virus on your PC).

    Thanks for the feedback. The zonealarm firewall is more of an outbound monitor, sort of a belt and suspenders approach, thats all. I like to know what or who is "phoning home"...
