belkin router slows down speed
 

Hello,

I have purchase a belkin wireless router.
I connect the router with my DSL modem and my Linux machine to the router through RJ45 port.
My problem is that internet slows down when I access net through my router. It works good when it is with the switch but router sucks.

I have tried many things most importantly I have tuned the router's firewall. Now it is disabled.
My ISP provides Dynamic IP and router is configured for that. Is there an y problem with the DNS ?

Please help.
Any information needed will be provided to you.

Thanks

It seems the problem is on your machine, not the router. Since the router is set up to get its IP from your ISPs DHCP server, then chances are it's also getting the DNS address along with that.

However, your machine is setup to use that exact DNS address and not the router (which is why it works fine when using a switch).

I'd start by checking /etc/resolv.conf and make sure the router's IP is in there.

Also, check the output of
#route -n
to see if your routing table is correct.

Hope this helps.

Hello,

My resolv.conf have the nameserver entry of my router's IP. and my routing tables are correct.
I want to tell you that my Pc connect to Belkin router - 192.168.2.1 and this router connects to my SmartAX MT880 ADSL Router - 192.168.1.1 which ultimately provides the internet connection.
Is there any clash between these two routers's ?

Please help !

Alright...

So the set up that works is (ISP -> SmartAX MT880 -> PC). Which when you change it to (ISP -> SmartAX MT880 -> Belkin -> PC) still works but you get very slow response times right?

using the first setup do
This will produce a lot of output, of which we only want to know the last 4th line from the bottom "Query Time".

Then change to the other setup and do the same command. Now compare the values of "Query Time" between the two set ups. If your problem is rooted in DNS resolution the difference in values will show it.

Also, please post which Distro/Kernel you're using.

Right now you have following setup:

ISP > Modem (does NAT and DHCP) > Belkin (does NAT and DHCP again) > PC

Doesn't make any sense this double-everything. Does it?

Hello,

I just solved my problem.

I shut down the NAT and DHCP feature of by ADSL Router(modem) and enabled my NAT and DHCP at the router(belkin).
Also I changed the MTU value for my connection to 1400 inside my Router. That helped me resolv the conflict I was getting.

Thanks for all your valuable suggestions.

Thanks
