two wireless routers on separate network conflict

By manny_kin357 ·
HI, HOPE SOMEBODY CAN HELP ME W/ THIS..GIVING ME HEADACHE FOR MORE THAN A MONTH...

I HAVE A 8-PORT SWITCH HUB CONNECTED TO LINKSYS WRT54G WITH A LEAST 4 OTHER PCs CONNECTED TO MY SWITCH HUB..

I DECIDED TO SUBSCRIBE MY OWN INTERNET CONNECTION AND BOUGHT A 4-PORT LINKSYS WRT120N-SG PLUS MY SWITCH CONNECTED TO IT...

HOWEVER, WHEN I INSTALLED IT, I ACCIDENTALLY CONNECTED ONE OF THE CABLE FROM WRT54G WIRELESS ROUTER (WHERE I WAS [PREVIOUSLY CONNECTED) TO THE SWITCH HUB WHICH GOES LIKE THIS


WRT54G CONNECTED TO MY 8-PORT SWITCH HUB WHICH IS ALSO CONNECTED TO MY WRT120-SG ROUTER.(ALL INTERNET CABLES SET AS HUB/ROUTER TO COMPUTER)

HERE IS THE PROBLEM....
1) THE WRT54G CAN NO LONGER BE ACCESSED VIA WIRELESS CONNECTED.
2) THE WRT120N-SG SOMETIMES GET DISCONNECTED VIA WIRELESS..

I HOPE I PROVIDED THE NEEDED INFO...TNKS IN ADVANCE

Try this

I am confused in your description, but here is a possible solution. I haven't looked into the ports on both of those routers, so I'll give you the basics. I would plug your Internet connection into the uplink port of the wireless router, then you can use any of the other ports to connect to the other switch. If you have to use the other router, do not use the uplink port, but use the other ports, that way it will be using the switch function instead of the router. Also, you should turn off the wireless function so that only one of those routers is broadcasting.

Idea

Ok, I'm also a little confused in what you have described.

You should post what you want your final outcome to be and we'll try to help as best we can.

But it sounds like you have both the wrt120n and the wrt54g connected too the switch. If both the routers are set as DHCP, especially if they are giving out the same ranges of IP's than its going to conflict all over the place.

My recommendation is to reset everything and start over. (reset button on the back of the linksys routers) If your trying just setup a wireless and wired network you only need the one router (I prefer the WRT54G, they are very reliable) Put the cable from your ISP (from the cable/DSL/SAT modem) into the WAN port than connect the switch from the uplink port to any of the 4 switch ports on the router. Honestly if the 8 port switch you are using is anything remotely recent it should be auto-sensing and not even need to be on the uplink port. At this point you can log into the router and set everything up as you need.

If you need the other router to set up a second network but still want it to get on line through the same ISP connection all you need to do is to connect ts WAN port to one of the 4 switch ports on the first router. This way it will use the first router as the internet gateway and you dont even need to change the default IP, although I would recommend it.

i wanted it to be separated

by manny_kin357 In reply to Idea

sorry for that, anyway i just wanted to have separate networking from the first router distinct from each other router...i am just concerned coz the first router (wrt54g) can no longer be accessed via wifi..

i did all the resetting...reinstalling the router...renewing ip from default 19.168.1.1 to 192.168.2.1 but i got error...tnks

more questions

by artanyis In reply to i wanted it to be separat ...

Do you have more than one internet connection?
Do the two wireless networks have different SSID's?

If you want to keep the two networks separate and only have the one ISP connection than the way i previously described will work. You will have to use one of the two routers as the internet gateway.
eg: ISP connects to WAN on ROUTER1. port 1 on ROUTER1 connects to WAN on ROUTER2.
Make sure they have different IP ranges and the IP's for the two routers are different.

As for why the wireless is not working even after you reset it, I need a little more information. Do you have the wrt120n off and unplugged? We want to isolate the router as much as possible. Honestly we don't even need to have it on the internet but thats up to you. What we want to do is to log in to the router through one of the eithernet ports and check all the settings, make sure that the SSID is set and the wireless radio is broadcasting and change the channel to make sure some other network isn't messing it up. If this doesn't make any difference try a firmware upgrade, even if you already have the most recent version, do it anyway, this will clear out any corruption that may have occurred. Do not upgrade the firmware over a wireless connection, of course the wireless isn't working so not a problem.

Tried it

by manny_kin357 In reply to more questions

1. Yes, i have two different internet connection both from the same ISP provider
2. I also have different SSIDs

By the way i only shared internet connection from prior, but now i want my network separate from the other, the only problem is, the first broadcast its wireless but can't connect.

I've already changed the ip address.

Yes, i have it unplugged already several times, even reinstalling the driver

I also changed the channel.. the first is 6 and the other is 11

I'll have to try upgrading the firmware.

thanks for the suggestions...happy new year

let me know

by artanyis In reply to Tried it

If the firmware works

As long as they are not connected to the same switch there should be no conflicting DHCP or DNS requests. ATM Firmware is my last thought. But I'll keep working on it and see if I can come up with any other ideas.

Wireless problem

by egreen In reply to two wireless routers on s ...

I am not very clear on the total objective. If you deal with just the problem on the WiFi side, it sounds like you have an addressing conflict. If they are on the same subnet the first router will provide dhcp to users on the lower side of addresses and the second router should serve only IP addresses above the defined limitation you established in the first router. In short, Router1's DHCP addresses would give out only ( just as an example) addresses 192.168.1.1 to 192.168.100 The second router would be configured to distribute address from 192.168.1.100 The second router would do 192.168.0.101 to balance of addresses. The fault route should be set up as 192.168.1.1 on both routers.

good luck
