I’ve upgraded Mikrotik to 3.30 recently for a private network for sharing internet. The network was working OK for the last 3 years or so, but when I upgraded I just couldn’t make the routes to work, even though I did the same routes as before. I couldn’t “restore” the config file so I had to go back to setting up the network from scratch. I’d use ping to see if the routes worked or not.
Sometimes I would manage to get it to work, but after about 30 secs, the lot would break down. The wireless connection would break for a few seconds, and once it reconnects, the routes that worked seconds before, would no longer work.
I’ve read the wiki here, but can’t find what I’m doing wrong. I don’t mind a different set of ip’s, just as long as it would work. Also, I’m pretty sure I have the wireless side of things right as when I follow the instructions from the post above, it works fine. I’m not great at networking, but if there is anyone who can give me a working route for my setup, I’d be very grateful. I know you’re asked a lot of times for this kind of help, but after a solid week, and bad weather/leaking pipes/Christmas, I’m at my wits end.
That isn’t sufficient for router 2 and router 3, but your graphic doesn’t give enough information. We need the subnet masks on ideally ALL IP addresses you show, but at a minimum those of the Wlan1 and Wlan2 interfaces on router 3, and the Wlan2 interface on router 2. Once you amend the graphic the necessary routes can be added to the two routers. What I posted so far would get the Ether1 interface on router 3 up and running, at least.
Make sure you consult the current routing tables on all routers to make sure that new entries you’re making are duplicates, or clashing with other entries.
Really it would be best to post at least the output of “/ip address print detail”, “/ip route print detail”, and “/interface print” from the three routers, clearly labeling which output belongs to which router, and wrapping output in
Sorry, I forgot about the subnet masks. I’m at work at the moment, so I will update the graphic when I get home. All the subnet masks are 255.255.255.0.
Well, that’s bad. You can’t have two interfaces on router 3 on 192.168.2.0/24. Your graphic shows Wlan1 and Wlan2 with IP addresses on that network. That’s not going to work, you would have to assign a different network on Wlan2.
Why are you so opposed to /30s? That’s the proper way to form links between two routers.
I thought I would need to keep the ip’s in the same network in order for them to work. Whatever way I have it set up in my old configuration, it works that way. U use wds on router 2. Maybe that has got something to do with it?
With the 30’s will I be able to connect more than 1 computer to router 3? I wouldn’t mind using it at all, but I hope to set up a dchp server on router3 so that more than just two wireless products ( Laptop/ Wii /iTouch), will the /30 subnet not allow me to do that? Also, would they connect to it without having to manually set up the subent in the 30’s range in them? I know my graphic shows that I just need the PC and laptop connected to router 3, but as I say, I was hoping to allow other things to connect to it at a later stage, and didn’t want to over complicate things at the moment
The /30s would go on the links between the routers. Customer networks (networks on interfaces customers connect to) would get networks larger than a /24.
You can’t assign the same IP network to two interfaces on the same router. TCP/IP doesn’t work that way. I don’t see how it would have worked in your old network. Try using 192.168.3.1/24 on the Wlan2 interface on router 3, and add routes to it on routers 1 and 2 just like there are routes for the 192.168.1.0/24 network. That should do the trick.
Nice one fewi. Works fine now. I asigned the 192.168.3.1/24 on wlan 2 on router 3 as you said, and added routes along the line and it now works fine. Thanks a lot for your help.
Btw, if I was to use the /30 subnet on the network, would I still have to use it on wlan 2 of router 3 also?
No, you would change the IP addressing on WLAN2 of router 1 and WLAN1 of router 2 to share a /30, and the IP addressing of WLAN2 of router 2 and WLAN1 of router 3 to share a /30. Everything else would stay the same.
However, if it’s working now, might as well leave it as is.
