Solved IP Address Problems - 192.168.X.1 X is incorrectly assigned

[whitebloodcell]

I am trying to set up a network at home. We have two computers and two phones together. The computers run Windows 8 and Windows 7 respectively, and both phones are on later versions of Android. The Windows 8 computer connects to the network and has internet access with no problems. All other devices have issues. On the computer that worked, I typed iponfig /all, and noticed that the X in the IPv4 address of 192.168.X.1 was different between the working and non working computers. It was 1 on the working computer, and 0 on the other computer and phones. So I manually set the IP address of the laptop to 192.168.1.100, along with the subnet and DNS settings and voilà it worked. This obviously is not a permanent solution however since, among other reasons, this computer moves around from network to network and needs DHCP assignment, and I don't know how to do manual assignment on our phones.

Why is the X part being incorrectly assigned and how can I fix it?

If you are seeing two different default gateways it usually means that you have two routers in this network.

From what you are saying the first router is most likely a router/modem rather than just a modem then there is usually another router being used as an access point. This is a common set up problem and you end up with two DHCP servers and two default gateways which needs to be changed. Let me know if this is similar to your network because I can only guess from here.

In these types of networks there are a few settings that require changing in order for your network to have a single DHCP server and a common default gateway, the link below explains what is required for this to work.

Thanks for the quick reply. Yes that is the case, there is the main modem/router (a BT Broadband Hub) and a repeater (a TP Link WA-850RE), they both broadcast using the same SSID. My devices connect to the repeater, the others (my friends) to the main modem two floors up in my apartment block (or at least, they are physically much closer and have stronger signals from the repeater and the modem/router respectively). I saw no mention of DHCP settings during the setup, and confusingly the address which I used to access the settings (tplinkextender.net) now access a very different page, with no relation to my device. I assume if I know the IP of the repeater then I could access it using that? How can I find that out? Typing in the DNS Gateway address on this working computer brings up the BT Hub page.

It would appear that the default LAN address for the range extender is 192.168.0.254 or 192.168.1.254 so please try those to access your configuration settings. If that fails then please manually connect to the range extender and try your previous web address link.

Once in the settings please open the link below and follow Page 28 4.7 DHCP to access the DHCP settings for the range extender. Upon reacing the settings please press the disable radio button then save the configuration settings.

   Note

You must have the DHCP server enabled on your BT hub. If you have not explicitly disabled it the DHCP server it should already be enabled.

Hope This Helps,

I checked on this repeater and it says that DHCP is disabled by default and that you have to manually configure a few settings in order to get it working with your modem/router. The link below explains the process. It looks like they have you manually typing in an IP that is in the range of your modem/router.

It really pays to look up this information before hand.

As for the problems accessing your TP link repeater, they have a forum you can ask questions in, although it should be showing up at 192.168.0.254. There are also firmware updates in the second link.

DHCP is enabled by default for me at least. The IP of the main router is 192.168.1.254, so I set the LAN IP on the TPLink to 192.168.1.253, and set the Gateway and DNS to 192.168.1.254. I then disabled the DHCP server on the TPLink device. I can then plug my device in and it broadcasts as expected, however no IP address is assigned. The main router definitely has DHCP enabled, as everything works again (when within range) as soon as I remove the TPLink from the network.

You need to type in the gateway of your main router according to the instructions. You are typing in the gateway which they are showing as an example". I'm not sure what the gateway is on your main router but that's the one you need to type in.

The DHCP IP should be assigned from the main router and it should be giving you an IP in the correct range the second you connect to the A/P. You might try typing in a proper DNS server instead of the gateway.

The address they had in the example was in fact the address of the main router, I have it working now. The main router itself was upset somehow so I had to wait for my friend to reset it. How do I rep you? Can't see the little scale...

Yes it can sometimes be a pain just to get the main router to see the access point, there is usually some trial and error involved until you get it all set up. Little scale is upper right.

I'm glad you have it working now.
