How To Fix FTP Access Problems With The Belkin N Plus Wireless Modem Router?

belkin wireless router setup

Belkin N+ Wireless Routers are known for their efficiency and reliability, but at times, people get stuck at a problem, which is not related to the network, but something else. There are many things that we as common internet users don’t know, but that doesn’t mean those things don’t exist because they do.

Many Belkin Router users were not able to access FTP with their routers and they were not able to make out the cause(s) for the problem as well. But, they can take a sigh of relief as the solution to the problem is given in this tutorial, so they can go through it and fix the problem.

Identification of the possible problem

Here is what most people are seeing when they are searching for the solution to the problem.

The problem is a discrepancy in the MTU packet site and can be resolved by changing your NIC’s maximum packet size to 1000.

That discrepancy made us suspicious and we looked at the current MTU value in Ubuntu:

  ifconfig

Which returned a value of 1500 to both eth0 and wlan0. Checked the router, and the value was 1432.

This is precisely the discrepancy.

Solution

We decided to try to set them to the same value. In the router, we changed the value to 1492 (the standard for the PPPoE connection) and we did the same thing on the operating system:

sudo ifconfig eth0 mtu 1492

Navigation was as usual and it was not affected by any problems; so we tried FTP. We opened FileZilla and finally,, we were able to see files and folders! We try to download and upload via FTP: everything is fine.

We try this setting even with the wlan0 interface, because otherwise via Wi-Fi, we couldn’t use FTP:

sudo ifconfig wlan0 mtu 1492

We tried this and run everything as it should. However, these settings disappear when the system is restarted. We, therefore, modify the file/etc/network/interfaces:

sudo nano/etc/network/interfaces

That looks like this:

auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp

And we changed it like this:

auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp pre-up /sbin/ifconfig $IFACE mtu 1492 auto wlan0 iface wlan0 inet dhcp pre-up/sbin/ifconfig $IFACE mtu 1492

Asking the system to launch the command at startup.

Conclusions

Now, we don’t know the reasons why we had to change this value in Ubuntu. If we use the old Ethernet modem with its value set to 1400 and Ubuntu with its 1500, we have no problem. If we put the router, we have to match the two values ​​in the router and in the operating system.

We know the right process of Belkin N600 setup and Belkin Setup N300, so if you want to know how to setup N600 extender with the existing router setup of your house, then you will have to connect both devices in a proper way and after that, you need to connect both devices wirelessly.
