Router problem

Speedway

Hey i'm living in Boston for the summer and we've gotten cable internet into our house. The internet is fine when we connect from the cable modem to the pc using ethernet cables.

but we want to set up a wireless network. we've a Linksys WRT54G wireless router connected by ethernet to the cable modem. The wireless network is being connected to by my laptop no problem but we CAN'T get the router to get us to go online. we've gone into the router 192.168.1.1 and it doesnt seem to be picking up the ip of the modem at all

any ideas anyone? i can give more detailed info needed.

you could try to give yourself a staic IP address and ensure you also have DNS settings in or else you wont be able to surf,

Hi,

Make sure that the modem and router are not on the same IP address (192.168.1.1) as this will confuse the routing table resulting in no internet access, change the modem ip to say 192.168.2.1 and everything should be fine assuming cables are in correctly

1. Firewall is blocking it

2. You have an IP specified in your WLAN connection that conflicts with the router

3. You have an Intel Pro Wireless chipset, which is incompatible with half the routers on the market. Fortunately, most issues arising from this can be resolved by updating the drivers for the wireless card from intel.com and upgrading to SP2 if you haven't already.

4. You simply haven't read the manual ( though I don't believe you're that dim for the record ).

Edit: number three is unlikey if you're not even connecting to the router.

one thing i found useful is to use MAC address filtering. add the MAC address of your wireless modem in the laptop to the filtering table in the Linksys and it should pick it up. a benefit of this is that no one else can connect through your router without being added to the filter.

I set up the exact same router yesterday to work off my Belkin wireless card.

Goto a cmd prompt go ipdonfig /all

what IP address is comin up? Cos there was none when i did mine, then i had to release a new IP, and change the range to work of a 192.168.10 range

Simple thing to check, is the "Internet" light lit on the front of the router? If the modem IP is conflicting with the router IP the easiest thing to do would be to go into the router configuration and change the IP on the first page under Network Setup from 192.168.1.1 to something like 192.168.1.2

we CAN'T get the router to get us to go online.

How have you set up the router?

The modem might not automatically connect on its own. It may need to be driven by the router. Have you entered any settings or username/password info into the router or did you just plug it in and wait for it to work?

Is there an Info type page on the router that lists the router's current settings? If so, post the settings here (after removing or altering any username or passwords, of course).

Also, is there a logs page? If so, this may tell you what problems it has been experiencing connecting, if any.

we've gone into the router 192.168.1.1 and it doesnt seem to be picking up the ip of the modem at all

Generally the modem itself doesn't have an IP Address. It gives one to the device that it is connecting to the network. So your router should have two IP Addresses, an internal and an external. The settings/info page should list these.

Some really usesless advice on this page!

Right what I would do is connect PC to cable modem directly. Then open a command prompt (start->run->cmd) and type "ipconfig /all" Post the results here. That will give us a clue as to how the cable modem operates (i.e. does it give a LAN or WAN ip address to PC). It will also tell us if the router and modem have conflicting ip addresses.

Once you post info we can proceed better.

Which cable provider? For Comcast you need to run their registration software and then clone the PC's MAC address to the router:

Hmmm...your advice is as useless as mine...:rolleyes:

Right this may be extremely ridiculous advice but I'm gonna throw this out there because I'd like to know if this is true or not. You need to connect your wireless router to the cable modem using a crossover cable. Ahem...

Other than that I think the notion of the cable modem and the wireless router having the same IP address is a likely problem. The cable modem might not automatically be detected by the router as a modem either, so you might have to set your DHCP server to make the cable modem the deafult gateway for accessing the net. This problem is solved on the weireless router in our house with a port labelled "WAN port" that will make that the automatic defualt gateway.

I'm sorry if this advice makes no sense, I'm only beginning to learn about networking on the practical level beyond protocols and other assorted shíte.

might need to adjust the encapsulation settings in the setup page i.e. pppoe/bridge mode etc.

I have the same set up at home and never had any issues like this. The linksys website has some very FAQ's on it and there is a chat interface available to speak with a tech

that's great thanks for all the replies everyone, i haven't had a free minute to try fix it since i posted the question but thanks for the help

You may well be right about this. As far as I am aware you need to use a crossover cable if you are connecting 2 routers together, or 2 switches together. Crossover not required for switch to router.

You should check the IP of each to make sure they are not conflicting as mentioned before.

One other thing you should do is make sure that both devices are not acting as DHCP servers. Your wireless router is most likely acting as a DHCP server and giving you an IP address (Perhaps 192.168.1.x) but if the ADSL modem is also set up as a DHCP server it may also be trying to give out an IP address. This could mean its competing to provide IP's on the same range or worse on a different range such as 10.0.0.x

Basically to get around this you will need to either set your modem up as the DHCP server and ensure that your wireless router is DHCP-Disabled but on the same subnet, or just use static IP's.
Most importantly, if you run IPCONFIG/ALL you will want to see the modems IP address under Gateway otherwise you will never get out onto that crazy web place that everyone seems to use these days

Does that make sense or did I ramble on too much?
Let me know if I can clarify or help more.

^ Sounds about right. Hoep you get somewhere with this. Did your ISP give any advice? They might have a page on their website detailing how to add router to your setup.

Lol, yeah sometimes the easiest solution is also the best.
Probably the most sensible reply so far!
