Ping Timeouts? Routerproblems?

Hello everyone,
after setting up a MT 750G with a lot of forum help I had a few days of happiness…no things kind of are getting seriously rough. I have connection problems to the router, a lot of ping time outs, slow connections et cetera. Since the router is reached over a wireless connection, I still think the problem is the wireless part, but my boss thinks otherwise and doubts the router itself.
I’m still new to MT, working my way into it pretty slowly and I’m not sure, if something with my settings is actually wrong.
I know it is a lot to ask, but I’d really appreciate it, if someone could look through my config to check wether there are possible settings that might cause the ping timeout problems.
Perhabs some additional information: We are working as a little local internet service provider, using radio systems for our customers. As I mentioned before, I still think the radio systems or something else cause the problems, but my boss things differently. But since we are a local isp, we need that bandwidth limitation per client IP. And I’m not sure, if the bandwidth management I set up is a) correct b) so inefficient, that it might be the reason of the problems.
That’s it so far…if any more information is required, I’ll try to answer as soon as possible.

So here is the complete output of /export:

OK, the problem points more and more towards the MT 750G, I’m still not sure, what the reason is, but here is the situation: We tested several connections from other routers running in the same network (remember its a radio link system). Everything ran fine until I started pinging the router I have these problems with. Suddenly all the ping times within the whole systems rose up, timeouts got more frequent et cetera.
I’ll try to replace it to verify the problem. First with another router, to make sure it’s not the radio link to that station and then with another MT 750G.

Because you exported everything it makes it hard to determine what features you’re actually using. Any chance of cutting that down to the relevant information, and adding a network diagram?

Generally speaking the behavior (you ping one node and suddenly the entire network slows down) to me points to a bridging loop somewhere. You do appear to be running the switch chip, which makes the router act as a wire speed bridge.

Sorry for the late reply once again. Everything is upsidedown here, total confusion - never a good situation to work in :wink:
Right now I’ll leave it at that, thanks for your reply/concern fewi, but it seems the MT is not the problem yet again. I’ll come back to it, if the problems rise up again and I’ll check the config then. Need to figure out dual wan and ovpn ipsec first :slight_smile:
