I have a WRT54Gv5 Linksys Router and i want to set it up with my Static IP address. On Linksys' website it states to get your IP, Subnet Mask, and DNS number from your service provider and enter it on your router setup. When i enter these numbers in the Static IP tab it says that the subnet mask value is illegal. How can i find my true subnet mask value? Linksys Tech Support cannot help me therefore i came here. Any input would be great.

Since your ISP is providing you with a static IP, they will be the only ones that will be able to tell you what IP and mask they are providing you.

A lot of isp's just use dhcp and you should be able to plug in the router and it will get its address from the network by itself . Not all are like this but a lot are . I have a DSL setup and you just plug the router in and it gets its own address via dhcp from the provider.

This applies to D-link routers - I don't know if it applies to Linksys ones.
If you have printed manuals, there may be more info in them about what specific ISPs require in your region, and what settings you use - at least that's the case in several D-link router manuals I have seen.
In most cases the IP address is dynamic and can change slightly each time you connect depending of which of several servers it connects to. A Static IP address is not common and if available often costs you more for the package - if you paid for a standard cheaper package, odds are you don't have a static IP address.

How can you get the proper static IP adresses without calling your ISP. Im running a WRT54G with three computers. A ps3 psp and a laptop. I was able to run my laptop and psp using DHCP but when i ran 2 computers at once my server failed.
the ps3 was running a DMZ and 9 ports being forwarded all at once.

We get enough of a volume of posts on this site, especially in the Hardware and Windows XP forums, such that you are unlikely to get answers when the last post before yours is so long ago - it's too far down the list of posts for most people to even notice. The only reason I am answering at all is I still happen to have this subject in my MyComputing.net list.
You should post on the Networking Forum.
You can make a new subject and start a new thread at the bottom of any forum list of posts.But there are problems with your post.
"I was able to run my laptop and psp using DHCP but when i ran 2 computers at once my server failed."
Not enough info, and confusing.
Were the laptop and PSP able to connect to your ISP, or just to each other, when both are connected to the WRT54G?
Are all the connections wireless, or are some wireless, some via network cable?
What do you mean by "my server failed"?
What server - your own, or the ISPs you are trying to connect to, or are you saying you can't connect to the ISPs server?The WRT54G must be connected to a high speed DSL or cable modem in order to connect to your ISP/the internet. Is it connected to one?
It's the router that connects to the ISP's server via the high speed modem. Everything that plugs into the router should have no problem connecting to the ISPs server if the router configuration is correct.
As I said, most people don't connect to a static IP Address - it usually costs a lot more to do so - they connect to a dynamic IP address.

In general I have gathered the quality control of routers is rather poor, especially ones capable of wireless connections. A salesman at Future Shop told me he tried 5 wireless routers before he found one that worked properly.
If you don't actually need a wireless router, don't buy one.
Wired routers, wired network connections are more reliable than wireless ones, especialy wireless B and G ones.
......I searched on the web using: WRT54G and WRT54G V5.
Apparently even if everything is done right, a lot of people are having problems with this model.
E.g.Lots of info about the model series.
