I have a home network using a Linksys wireless router, (wtr54gr)which works fine, the IP of the router is 192.168.1.1, I have a notebook from work which has a manual conf IP of 192.168.0.13, is there a way that I can configure the router to allow me access to the internet, without having to change the settings in the notebook every time

Is it possible?

You could change the route's IP to something in the same sub net as your laptop, i.e 192.198.0.1, and set its DHCP range to anything that doesn't conflict with the one your laptop has, 192.168.0.14-254
If its working as a DHCP, it will then assign IP's in that sub net, and that range. It should then let the Laptop out.
----------------------------------
Ignorance is not necessarily Bliss, case in point:
Unknown has caused an Unknown Error on Unknown and must be shutdown to prevent damage to Unknown.

Well, the problem with that setup is that the notebook is still expecting to get a static IP address at 192.168.0.13, which is not part of the IP range you set. So you will still have to manually set the laptop to DHCP, then back to static every time when you go back and forth.
Consider using static IP's in your house, especially since you have wireless. It adds more security to only allow the same number of connections on your router as you have computers. You assign one IP to each computer specifying their MAC address (in this case, you would definitely assign 192.168.0.13 to the laptop). That way, even when the laptop isn't around, its IP is reserved and can't be swiped by another nearby wireless device in your neighborhood. Having WEP or WPA encryption is good and all, but restricting the IP address assignment in this manner is even better. Plus, the other upside is you don't have to keep flipping DHCP on and off.

I'm not sure I follow you here. On the wireless router, there will be a setting to specify the IP address that connections are "allowed" to start at. If you specify that as 192.168.0.14 or higher, then any IP address "below" that will not be permitted to connect.

Not true (unless thiese router is wierd), one is DHCP leasing address, the other is subnet address. If using Class C (255.255.255.0) Then any thing between 192.168.0.1 - 192.168.0.254 is a valid address, regardless of what DHCP is handing out.
DHCP scopes are NOT the same as Permitted address however.
If it were the case, most businesses would fall flat on their face (I'm suprised they are using statics!).
As exapmlt you may have a DHCP scope that runs x.x.x.50 - x.x.x.250. You then may wish to use the lower ranges for likes of managed switches, Servers, Printers and anything else that likes fixed IP. Then any pc's that are put on are dished out IP's in the range 50 - 250.
So setting a scope of 14 upwards still allow his static to work.
Only the truly stupid believe they know everything.

Thanks, I think I covered that in my first post above.
All,
Yes, I now I understand where you're coming from. On older home routers (like the Linksys BEFSR41), you only had the option of setting DHCP or static, but not both - this is one of the most basic routers out there.
But I checked my newer D-Link DI-624, and saw the option to specify static IP's independent of the DHCP range. So I apologize to allisland for any confusion.
However, going back to having a good security model at home, it would be best to disable DHCP altogether (forget about the range we spent so much time talking about), and just assign static IP's by MAC address.

Or of course if you are running XP you can go into the TCP/IP properties and use alternate configuration. Set the alt config with the static and the general with the dynamic. When the dynamic is not present it will fall to static. Vice versa would probably work as well.
Even if you do have an older router like that, you can still do what is described above. You can configure a router to pass out IP addresses (DHCP) or have you manually assign IPs (static). You can configure a PC to automatically get an IP from a server (DHCP) or you can manually assign the IP (static). There are options on both the router and the PC for this, and they don't necessarily have to match to work.
The router will be able to route to and from anything that is a) on the same subnet as one of the router's interfaces, and b) uses that router as the default gateway. So if the router's IP address is 192.168.0.1 and it uses a subnet mask of 255.255.255.0, then you have 253 other addresses on that subnet that will work with the router.
On some routers you can manually configure the IP addresses used in the scope, or set exclusions on IP addresses that you don't want the router to assign to devices. Even if the DHCP server doesn't pass out those IP addresses it will still be capable of routing traffic to/from those addresses, so long as it is on the same subnet. So you could set the DHCP scope to be 192.168.0.20-192.168.0.254 and have 192.168.0.2-192.168.0.19 free to assign statically, which is what was suggested here.
If you cannot configure the DHCP scope on your router, a somewhat ugly workaround that should suffice would be to assign static addresses to devices from the upper end of the DHCP scope (192.168.0.254, or .253, etc) since it is unlikely that you would have 200+ devices on your home network. In the case above he can probably still get the same effect with using the .13 address if he has fewer than a dozen devices on his home network.
Alternatively, he could switch his entire network to static, then statically assign everything. This isn't much of an issue if you only have 1 or 2 devices to configure.
However, I think that the best solution for this particular issue is probably just to set up profiles on the laptop so that it is DHCP at home and static at work. Assuming that he has the correct permissions to do so, which he may now.
Sorry, got away from this thread. but kmcferrin has explained it correctly.
In all the routers i have encountered, be them wireless or not, you can specify a range of IP's that can be assigned by DHCP. Any addresses out side of that range will not be assigned but will still work with the router, if they are in the same subnet.
Its like having a lot of cars for employees.
You can have 20 cars. 15 you assign dynamically to the employees on a need to have basis. 5 are for the Suits and high management which you manually assign to each, person.
The fact that they can't be assigned by the Parking lot controller to any employee, does not preclude them from being used by company employees to which they were assigned.
Same with IP's the laptop knows its going to use that IP. so it can use it in any network that works with the same range. Excluding that address from the DHCP, is to avoid getting it mistakenly assigned to another PC. You would then get IP conflicts. By excluding it from the DHCP range, the IP still works with the router, but you avoid any conflicts.

to all who replied-
my original router would allow me to change it's ip, but then ceased to work , had to reset to factory default,
just borrowed a newer router was able to change IP, and set dhcp range all is working, will have to replace the original router.-- thanks to all

I used a cheap router that I converted to an access point(quite easy to do) and a primary router. the work laptop accessed the cheap converted router and kept all the work's IP range and then the laptop was able to log into the work IP
