Adding a Router -- WAN lost

Specs: Microsoft Windows 7 Home Premium, 2.7 GHz / 3327 MB
Following Curt R and Majorleap's advice, I tried to setup my network, again.

I have been running a D-Link DSL2640B with no problem, but wanted to add another router (D-Link DIR-655) for better range with my wireless.

Used the LAN to WAN setup, as had tried the WAN to WAN, but couldn't get my laptop to connect to the 2nd router (this may be a separate issue).

I have tried this twice trying to follow the advice. Network works fine -- can't get to the Internet.

Have tried setting Router #2's WAN as DHCP Dynamic and as Static, without much luck. I'm sure I've missed something, but probably don't know enough to see my error.

Can not find a RIP option, if that matters.

Would appreciate any help you could offer!

Because of the firewall of the router, that works between WAN and LAN interface of each router.
Why don't you simply make a LAN to LAN connection and
as already configured, only one router that runs DHCP.

"Used the LAN to WAN setup, as had tried the WAN to WAN"

Little confusion here. You can't do wan to wan with the second router because the first routers wan port is connected to the internet.

Lan to Wan means cable in lan port on router1 to wan port on router2. Most likely reason this failed is because you did not change the lan subnet on router 2. Odds are it has the same subnet as lan on router 1 so no routing can take place. If router1 lan is 192.168.1.x the lan on router 2 needs to be 192.168.2.x for example.

Usual way to set this up is per this diagram

Don't want to run LAN to LAN because it won't seem to allow me to connect with wireless to the 2nd router, though like I said, that may be some separate issue that I'm not seeing.

Didn't mean to say WAN to WAN. Meant LAN to LAN.

Should have added that I have all static IPs.

Have router 1 LAN set to

Router 2 WAN: Def:

What am I not getting?

by doing lan to lan you turn the 2nd router into a glorified wireless switch. it also allows computers on the first router to communicate with those on the 2nd router. This is why lan to lan for 2nd router is recommended.

what ip did you assign the wireless laptop?

Your config for lan to wan is correct.

I may switch to the LAN to LAN if I can't get this to work. It just bugs me because others say this should work. The wireless is assigned In my LAN to LAN setup, it would connect to Router #1, but Windows said it couldn't connect to the 2nd router, though it sees the connection. I may have figured out that one. If I can't get this to work, that's the direction I'll go.

I know my error has to do with the Internet connection on router 2.

Here's what it asks, depending whether I choose Dynamic DHCP or Static IP:

Static IP Dynamic
Def Gateway
Prim DNS
2nd DNS
MTU: 1500

I'm just sure this is where I'm going wrong.

shouldn't have listed twice but that shouldn't effect access.

Are you connecting to the 2nd router wired???? You need to so wireless isn't in the mix for troubleshooting. From a wired workstation ping the local gateway and then router1's gateway. Are you successful?

Yes, I am connected by wire. I have an embarrassing confession to make...I had turned off DNS and DHCP in Windows services, because I thought the router took care of those functions. Evidently not. It then worked with the LAN to WAN setup, but still couldn't get wireless to work even without static IPs.

So went back to LAN to LAN setup. All is working, though the PC on the #2 router loses connection now and then and wireless still can not connect with #2 router. I'm beginning to think there's a router problem.

The laptop sees the #2 router, but Windows says it can't connect, but it can connect to #1 router. I'll call D-Link again tomorrow and see if I can convince them that it's the modem. Have done this once before -- wish I could get someone who knows the modem instead of someone who barely speaks English and has to continually run off and ask someone else.

I do have both router configured to use different wireless channels and result is the same if I disable wireless on #1.

Any thoughts?

So if both routers are connected together by wire, I would now try to configure the router #2 with it's own channel and it's own SSID (network name).
Then try, whether a wireless connection connection to router #2 will work.
If so, configure the SSID the same as router #1 and leave the rest as is.
And again try to connect to router #2.

Btw.: I suggest to choose a channel for router #2 that is channel of router #1 + 5.
E.g. if router #1 is on channel 1, configure router #2 to use channel 6.

I named both routers and wireless connections when I started on this troubleshooting path. I had #1 wireless on Ch 1; #2, on Ch 11. Changed #2 to 6. No change.

Sooo frustrating!

"turned off DNS and DHCP in Windows services"

FYI but it takes two parts to work. One has to provide the service [the router] and the other has to be the client [your laptop/pc]

Ok, so first, in that configuration, I mentioned in Response #9, is it possible to connect wirelessly to router #2?

If yes, router #1 LAN side has the ip address /
So sonfigure router #2 LAN side to /
Save that settings and use the diagnostic of the router #2 and try to ping router #1 (

Post result.

Yes, I found that out the hard way, but appreciate the explanation. I didn't know it had to be in both places.

Can't believe it! After 1.5 months of fighting with this, D-Link confirms that it is a hardware problem with their router!

I'm so relieved. Thought it was me. A new router will be provided by them.

Thank you so much for all your help!
