Hi all,
I recently purchased a Linksys WRT54GS V1.0 router and have flashed it with OpenWRT using X-WRT (Whire Russian 0.9). The firmware and Web-interface are updated to the latest version. (WebIF r3978, Linux Kernel 2.4.30 #1)
I'm in UK, on Virgin Media Cable internet connection and use a cable modem supplied by them. No username or password are needed to connect - it's just plug and play. My current router, a Netgear FR114P, works fine when hooked up to the cable modem and picks up it's IP/Subnet Mask/DG automatically.
The new router works fine on the LAN, but it cannot seem to see my cable modem nor my Internet connection - It can't ping the modem when directly connected to either the LAN or WAN ports, whether pinging from a connected PC or directly from the router's diagnostic page. I'm wondering if I've configured something poorly?
I have a couple of questions that I'd like to check over with you guys - Knowledge of OpenWRT or the FR114P would be useful ^^.
1. Regarding dynamically getting an IP address from the ISP - The FR114P simple has the option Get Dynamically from ISP or the option to set it statically. Reagarding the options, it says this:
The options that OpenWRT give, however, are:
* None
* DHCP
* Static IP
* PPPoE
* PPTP
Given that "None" seems to disable any input regarding the WAN port, I know I don't have a static IP, and PPPoE requires a password, am I correct to assume that my ISP is assigning IP addresses via DHCP? Does anyone know the specifics on this regarding Virgin Media in the UK?
2. Just below these connection type options on the OpenWRT, are a couple of text boxes with the options to set manual WAN IP Address and the Subnet mask, "in case the DHCP server is unavailable". Is it worth setting these values to the values shown in my FR114P as being assigned by my ISP? Bear in mind that the IP is not static and will likely change in time. Also I assume trying to force a static IP when my ISP is set up with DHCP is probably a bad idea.
3. There is also the function on the OpenWRT to make the router use OpenDNS servers rather than the ISP's DNS servers. I appreciate that this shouldn't be affecting my ability to connect, much less ping my cable modem, but I'm guessing it would be best to leave this disabled?
4. Under "LAN configuration" in the same page on the OpenWRT, I have the option to set a default gateway. Should I set this to my cable modem's internal IP (192.168.100.1), my external gateway IP as assigned by my ISP (an 82.19.x.x address), or just leave it blank altogether? Or set it to itself? (The OpenWRT router's IP).
5. VLAN configuration in the OpenWRT. There are two default VLANS: 0 and 1. I've read in different places that 0 might be the WAN more, or 1 might be. The available ports are:
eNet 0
eNet 1
eNet 2
eNet 3
WAN
Internal
The default setting (AFAIK) is for all of the above to be a member of VLAN 0, and for eNet 0, WAN, and Internal to be a member of VLAN 1. That's how I currently have it set up.
*Is this incorrect? Will the VLAN affect LAN > WAN connectivity? (I'm assuming "yes" from what I know about VLANS).
*Does anyone know for sure which of those options is actually the WAN port on this router, V1.0 (Apparently it changes with the version of the router).
*Does anyone know why there is a WAN option as well as all of the individual ports, and what it affects?
I can get log file or information from either router for anyone who needs them. If someone here thinks they can help and are fairly "established", I'd be happy to give you remote access to my FR114P router for you to collect information (Sadly, I can't get my WRT router online to do the same. Obviously!
Any other information you can provide is extremely helpful - any insight into the working of Virgin Media and things I might need to configure to connect to their cable modems, or knowledge on configuring the OpenWRT (The docs are a bit sparse: Linky) - all these things would be very helpful.
Sorry for the long post, and thank you for taking the time to read it! I appreciate any advice with this that isn't "Just flash the proper firmware back over the top and use that" .
Thanks!
P.S. Just a couple of things I forgot to mention - I've also tested restarting both the cable modem and WRT router to make sure it wasn't just getting "tied" to the FR114P. The computer I'm using to configure the WRT, my laptop, is plugged straight into one of the WRT's LAN ports, and the WAN port then connects straight to the modem using the same cable that was being used to connect my modem to my FR114P - so I know the issue isn't to do with the FR114P, my switch, or a cable issue.
Also, I can ping my cable modem's internal IP (192.168.100.1) through my main PC (via the switch and then FR114P) when it's all connected up, and can connect directly from my laptop to the cable modem when it's plugged in directly. But plugging the laptop into the WRT, I cannot ping nor access the cable modem even when the modem is connected straight into either the WAN or LAN port.
Also the section in my WRT that picks up the WAN address via DHCP (Status > Interfaces), picks up an IP fine from my FR114P if I plug it (the WRT) into the FR114P, so I know that both the WAN port and dynamic DHCP allocation are working fine on the WRT - but upon connecting the cable modem to the WRT, it never picks up the external IP, even after restarting the modem and/or router. The FR114P picks it up every time.
Also, I have installed most of the "optional packages" suggested on various pages. I have only used 42% of the /jffs memory, which I'm guessing is the main memory as it increases when I install a package.
Anything else you need to know, just ask.
Thanks again!

Basic Settings Help
Note: If you are setting up the router for the first time, the default settings may work for you with no changes.
Does your Internet connection require a login?
Select this option based on the type of account you have with your ISP. If you need to enter login information every time you connect to the Internet or you have a PPPoE account with your ISP, select Yes. Otherwise, select No.
Note: If you have installed login software such as WinPoET (from Earthlink) or Enternet (from SBC or others), then you have PPPoE. Select Yes.
Note: If your ISP is Telstra Bigpond Cable, select it under Internet Service Provider Name. If your ISP is Austria Telecom (or another ISP that uses PPTP for login) select it. Otherwise select Other(PPPoE).
