Help setting up secondary router

post #1 of 7
Thread Starter 
Hi there,

I have a Virgin Media SuperHub 2 in my downstairs front room. WiFi signal is almost non-existent in the back yard or upstairs at the rear of the house, so I have bought a Tenda N90 and flashed it with tomato to use as a secondary router.

I have had this working, but after changing a setting somewhere, everything went haywire and I couldn't get it set up to work again.

I'd like someone who actually knows what they are doing to give me some advice, rather than trying to fuzzle it myself.

The SuperHub has a 2.4Ghz wireless channel and has ethernet connections to downstairs PC, Wii, TV and to a NetGear PowerLink, which is currently linked to a PowerLink in my study which connects to my work PC.

I would like the upstairs PowerLink to go to my Tenda router so that I can ethernet to my PC and Laptop, and use the 5Ghz channel (with a different SSID) of the Tenda so we have fast wireless access at the back of the house.

When I try to change the IP address of the Tenda from 192.168.1.1 to 192.168.0.100 (no need for different subnets, right?) I lose the ability to get into the admin page of the Tenda. ipconfig /all returns a blank for Default Gateway

My knowledge is very basic, so if you can help me set this up, I will be very grateful!

Thanks in advance,

J

I think the issue may be with DHCP. Make sure only the main router has DHCP enabled, it will provide an IP to the second router. You can set this up as static if you want the IP of the second router to be static (so you can access it for editing settings.)

Your routers should be in the same subnet, preferably with static addresses. What subnet mask is your primary router using? I'm assuming it would be the /24, and if so changing it from 192.168.1.1 to 192.168.0.100 puts them into different subnets and won't be able to communicate with each other.

Hi, thanks for your responses.

My primary router IP is 192.168.0.1

the Tenda initialised IP is 192.168.1.1

I haven't got them linked yet, i'm just plugging the Tenda direct into my laptop (with no internet connection) and going into the router admin page to change settings before linking to the primary router.

When i try to change the IP of the Tenda, it just disappears and i have to reset it to access the admin page again frown.gif

If you're setting up wireless for different SSID's, I believe they should have both SSIDs on each router and both routers configured with the same subnet mask.

Why are you trying to change its IP? Just set up the wireless using ap or whatever tomato calls it. Then connect the Ethernet ports together on the routers, don't use the WAN port on the second router, just the LAN ports. You may also need to disable the firewall and DHCP server on the second router.

ok, you're kinda halfway there. Go into the tenda router console again.

Change the LAN IP to 192.168.0.2

Subnet mask 255.255.255.0

Set the Default gateway to 192.168.0.1

If the DHCP server settings are in there, turn it off.

apply the settings - now at this point you WILL loose connection to the router, but that is ok, and expected, because you've changed the IP address(!), and also if DHCP is turned off, your laptop can't get a new IP addy off the router. The next step you missed, is first, set up the laptop ip address manually - 192.168.0.10 should do again set default gateway to 192.168.0.1, and then put the new IP address into the browser address bar - so put in 192.168.0.2, and you should be able at that point to log back into the router web console.

The reason for this step, is that with DHCP turned off, if you're just connected directly to the tenda, it won't allocate an IP address to the laptop. so you have to manually enter one which is on the same subnet as the new router address to gain access to it again. if you don't change the address, it may just sit on a 192.168.1.x addy, which won't access the router on 192.168.0.2 as they are on different subnets.
