Wireless Networking Problem

[PetrolTed]

I installed my Linksys stuff earlier and it all worked a treat. Now I've cocked it up somehow and can't get it to work properly.

My desktop can talk to the router via the cable.

My laptop can talk to the router via the wireless link.

However, I can't ping the desktop from the laptop or vice versa.



Any help would be greatly appreciated!

Are laptop & desktop on the same subnet?

Are you using DHCP (from the router, or from another server) for all devices?

What happens if you connect laptop using cable rather than wireless?

[PetrolTed]

Cable worked. Installed Linksys stuff and that worked. I fiddled with the settings and now the network drives won't map and I can't remember what I did

Ted as someone said to me check that a network bridge hasnt been setup.

on either of the machines

Or have you enable the firewall on the router??

I did and it f**ked everything up to start with until you finish every step of the configuration

Wirelessly or wired or both? I presume you can now ping the machine you are trying to map a drive to (by hostname)? Does it just time out or do you get a more meaningful error?

What does 'net view \remotemachinename' give you (from the command prompt)?

[PetrolTed]

Wired has worked for a couple of years. It's the new config that doesn't work.

I can't ping the desktop from the laptop or vice versa.

net view gives network path not found.

How can I simply test the pinging of one machine to the other and when it fails what should I look at?

you could try typing ipconfig on each, check the ip address of each, ensureing the first 3 sections are the same i.e. 192.1.1.***

Depending on what you see, this could give you a clue? Something called the Default Gateway needs to be your Linksys router....

Then try pinging from one to the other?

Yep, IP's are correct and the default gateway is correct but I can't ping them. The software firewall is set up to allow that address range so it's not that.

TED check in the linksys setup if the firewall is enabled there???

I got one on my buffalo router and it works but stops all network traffic as a default.

Also try and give your linksys a restart from the setup menu.

or if all fails restore to factory default and configure again.

Ping disabled by the firewall?

i had a problem with my Linksys wireless a short while ago.

Download the latest drivers for the recieving card for the laptop. the drivers are not only drivers but firmware as well.

This has fixed 9/10 of mine and customers linksys related connectivity problems.;

If you have any further problems then let me know or mail me offline as I sell and implement this stuff for customers.

Doh... it's always the obvious thing which is the first you dismiss. It was my firewall. The new network is on a slightly different IP thingy...

Sorted now. Thanks for the suggestions.

Ok, next challenge is to share my ADSL connection. I had this working when I was peer to peer but can't get it working via the router.

The desktop has the cable modem (USB) and ICS is enabled on that connection. The laptop won't detect that though.

Has anyone got any idea on the sort of diagnostics I could run to determine why the laptop can't see the internet connection?

[stc_bennett]

TEd my router is on 192.168.11.x and my internet connection is on 192.168.1.xx

Ted i am assuming you have connected your ICS Cable to the WAN port of the Router??? If you ICS is setup using DHCP you will have to do a resart to obtain a IP address and Gateway.

Then on your laptop i had to put both gateways in the IP setup.
Gateway for Router 192.168.11.x
Gateway for ICS 192.168.1.x

Then give your laptop a resart and if all things work as they should then you up and running

Steve

[PetrolTed]

Nope, my cable modem is a USB type and won't plug into the router.

Does that mean I should alter the gateway on the laptop to point at the desktop rather than the router?

No wonder you IT bods get paid so much...

You lost me at the line 'I have a problem...'

Sorted!

Ted

You have a network card in your desktop connect that to the WAN port of the Router.

Keep the desktop network card set to DHCP..
On IP address 192.168.0.1

Your router should pick up after a restart a IP address and Gateway for the internet.

Then once you resart the Latop you whould have internet on there.

It sounds like you are just using your router as a v.expensive switch.

Even though the Netwrok addresses are different you should in theory be able to see both networks.

Inherently the Router IP address on mine is fixed at 192,168,11,,x and i cant change it. My other network is on 192.168.1.x and they can see each other not to sure how it works though..

Steve

[stc_bennett]

How you do that then??

ted is the the linksys router you got the one that has a usb conection as well as lan.

Im confused why you useing ICS as the router should be taking care of thar not the micky mouce ICS

anyway if you cable modem conected buy usb.

i aint seen on that dont have a lan port as well in the uk

I would sugest you hook it up by lan not usb

as usb takes a fair bit out of the cpu
