Hi

This may be a very simple question but today of all days I have like 1 million things to do and don't have time to sit and play with it

I have windows 7 downstairs plugged into a dlink wireless router, this has all my media on it which I want to access upstairs on several PC's

I have it plugged into a switch upstairs which is then plugged into a TP wireless router

I have an XP machine plugged into this TP wireless router and it gets internet, also it is getting its IP from the TP router, i did try to disable DHCP on the TP router but when it got its IP from the Dlink it only worked for about 20 seconds then it dropped the IP

Win7 and XP cannot see each other?

Can anyone recommend some troubleshooting steps pliz.........

Thanks

You should be able to change the LAN IP on the TP router. This router isn't connected to the WAN so it shouldn't have an IP configured to it?

I can only change the LAN IP as long as the third octet stays 1

My WAN ip is dynamic, the third octet of this also cannot be changed from 0 to 1 or i get same message, LAN and WAN cannot be in same subnet

What type of router are you using?

Maybe you need to flash that annoying router with firmware from www.dd-wrt.com | Unleash Your Router, the firmware phoeneous is using.

D-LINK DIR-615 downstairs with Win7 client

192.168.0.104
255.255.255.0
192.168.0.1

TP-LINK TL-WR740N Upstairs with XP client connected

192.168.1.100
255.255.255.0
192.168.1.1

So I'm reading the manual of this thing on the bottom of this page:
Download

And I have to say, this thing looks pretty weak. I know you can do this on any linksys and netgear but it doesn't do a good job of showing the gui. DD_WRT for the win like P said lol.

Routers usually have a 4 port switch with a internet connection port. Bypass the internet connection port, plug both sides into the 4 port swich, kill NAT and DHCP on the router and it should be a switch.

I have never tried to change firmware on my routers. Is there any danger to doing this? What if it mucks things up and I want the default firmware, is that easy to stick back on it?

Lee H

Gonna try to change the downstairs IP to 192.168.1.104 see what happens

Think I paid about £17 for it, lol

My Dlink is off Virgin Media

Here is the router compatibility page to see if it's safe to work for your particular router:

Supported Devices - DD-WRT Wiki

For your second question I would assume that you could, but I would ask phoeneous as I have never done it myself.

I have a couple older Linksys routers lying around, I might have to sit down and have a weekened project sometime.

Now all we need is an all-in-one BIOS firmware for OEM machines, locked-down OEM BIOS is an Abomination!

Hi

Does anyone have any idea why i cannot have my LAN IP in same subnet as my WAN IP

LAN
MAC Address:
00-27-19-FF-43-FA
IP Address:
192.168.3.1
Subnet Mask:
255.255.255.0

WAN
MAC Address: 00-27-19-FF-43-FB
IP Address: 192.168.0.102 Dynamic IP
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Server: 192.168.0.1 , 0.0.0.0

The WAN i on Dynamic IP, and i can change it to static

If I give it an IP of 192.168.1.100 and the gateway 192.168.0.1, it tells me its a bad gateway, am i right in saying without 192.168.0.1 in here I would have no internet, which means the WAN ip has to have "0" in the third octet

Because that's not how networking works. It's like having an office building with 50 offices, each one has it's own suite number.

That doesn't really explain the need for 2 different subnets, when you reach more than 255 clients isn't that when you introduce a new subnet

I also could do with learning CCNA, maybe that would help but for now I just need access to my win7 pc, grrrrrrr

You don't need different subnets for this if you are using the TP router as I described. I honestly think at this point you need to just plug everything into a switch and call it a day. you could have configured rip by now as well.

The number of clients is irrelevant, the path that traffic takes is more important. If you need to get IP traffic from one router to the other, the sending router needs to know what destination address to send it to. Just like if you need to visit someone in that 50 office building, you need to know their suite number. If all 50 offices had the same suite number, you wouldnt know which office to go to. You cannot have two different interfaces on the same subnet, it doesnt work like that.

If you want access to your Win 7 pc then plug it into an open switchport on one of your routers. Then plug your xp machine into an open switchport on the same router that the Win 7 pc is connected to. Disconnect the other router completely and put it away, you don't need it.

You're making this too difficult for yourself when really it is very simple.

I totally agree, if I knew I was going to have this issue I would have bought a switch and not a wireless router, will be purchasing a 6 port switch, plugging 4 PC's and the link from downstairs into it, leaves 1 port for the TP router to give upstairs wireless, no PC's will be plugged in to the wireless router so this should work fine

Thanks for your help guys really appreciated

This thread hurts my head.

I wonder if this ever got fixed....

Lee H

No it didnt

My TP router will not allow me to put it on the same subnet as my Dlink, same arror keep coming up

Seems I have to buy a switch instead, shame cos I thought it would be possible to make my TP router to work as just a switch?

It funny how the TP picks up my gateway as being 192.168.0.1, which is the IP for my Dlink

Dont know enough about this area of IT to fix IT myself so will have to buy a switch

Bl8ckr0uter

No offense but this is extremely basic networking. I suggest that you pick up a network+ book (NOT a CCENT/CCNA) and take a week to read it. It will only help make you better. Just my 0.02.

The TP picks up your dlink address as the gateway because you're dlink IS the DG for your TP and gives it via DHCP.
Anybody know what port network discovery uses? He could unblock that port on the TP and the Dlink and have the problem fixed.

Bl8ckr0uter

Doesn't network discovery use a collection of services?

Well apparently it is built off of this http://en.wikipedia.org/wiki/Link_Layer_Topology_Discovery

So from what the article says netwok dicover doesn't work across routers so set up a upstairs and downstars switch and anything youy want to "see" each other has to be on the switch. He can still use the wireless router upsatirs but none of them can see each other.

>---router--switch---upstairs---switch--router
and plug all comps that want to see each other into switches. The problem with using the router as a switch is that it's built(internally) like --router--switch
Has the OP tried devilsbanes suggestion of plugging the cable form the downstairs router into one of the switch ports of the router?

I don't think so. IMO he just needs to go downstairs router--switch---upstairs switch---PCs and call it a day. Who knows if the pos TP router will even truly function as a switch like that. Spend the 15 dollars on a netgear 10/100.

I did not read this thread just the OP, not sure if this has already been addressed.

For Win 7 too detect Win XP PCs on a network via network discovery you need to install LLTD responder on the XP machine.

so this might be part of the issue.

Download details: Link Layer Topology Discovery (LLTD) Responder (KB922120)

The LLTD responder must be installed on a computer running Windows XP before it can be detected and appear on the network map. After you install this item, you may have to restart your computer.

Good IDEA!
I read the article and didn't even thing about that. But even still he is having other issues. from what I can tell, he cannot even ping the machines.

@P

It was probably automagically included in SP3. I have never had to do this either.

modem--router(DLINK)--upstairs---switch--router(TP) this is my setup

The switch upstairs is only to continue the signal into my boys room

When I plug the link from the DLINK router into either of the 4 ports on the TP I retain the same IP and lose internet

If this is only basic networking then am not doing too well, lol maybe its not my fault and as someone has suggested my router will only ever function as a router

"It was probably automagically included in SP3. I have never had to do this either."

XP is on SP3

earweed

My setup is
modem--router

switch--PCs (with 1 PC conected straight to the router and 1 wireless)
I can "see" the pc that's wireless off the router but not the PC conected to the router and I can see all the PCs connected to the switch. Just put a switch downstairs and connect your XP to the upstairs switch and you should be fine.

Without going out and buying a new switch my setup will have to consist of 3 things

I have to have a router downstairs to get the internet feed for my wireless, main pc is in living room connected to this router, using one of the ports cat5 goes out of the house up the front and into my bedroom, the cable is only just long enough so in bedroom i have connected a switch, from here it goes into my TP router, maybe I should have invested in a more expensive router one that could be set to function as just a switch

Will soon buy a switch so will no longer have this problem

I have mine set up the almost the same way

Basement Router
WAN 1 Web

LAN 1 PC
2 Switch 1
3
4

Upstairs Router
WAN 1 NO CONNECTION

LAN 1 Switch 1
2 PC
3 PC
4

Switch connects both routers and additional PC and DirectTV boxes.

DHCP is enabled on the Basement router
WAN connection is from dynamic from cable co.

Upstairs router is wireless and has DHCP disabled
WAN is set to get DHCP address and since it is not connected all traffic flows to gateway on basement

Network is 192.168.15.0 /24
Basement router 192.168.15.1
Upstairs router 192.168.15.5
Gateway 192.168.15.1

All of your IP's are *.*.15.*

Trouble I have is my router downstairs has *.*.0.* and my router upstairs has *.*.1.* and this cant be changed to the same number
