Recently i have switched to Cisco Linksys E900 for my broadband connection. After configuring the router, my internet connection started working fine on Windows 7 and Samsung Galaxy smartphone. I thought that router has been configured properly, but i was wrong. There may be multiple reason for not working but i am putting one solution that might fixed the problem.
I tried testing the internet connection on Ubuntu but to my shocking i found that yahoo is working very slow which was not the case before switching to Cisco Linksys Wi-Fi Router E900 🙁
I start searching on internet for the possible solution but it did not worked but finally came to one article mentioning about MTU which is configured between 1400 – 1500 depending upon your internet connection.
Where is MTU in Cisco Linksys Wi-Fi E900 router?
- Choose your favorite browser
- Goto 192.168.1.1
- In most of the case your username and password is admin/admin
- Choose Setup->Basic Setup
Be default the MTU configured was 1492 which was not working properly. I came to know this by using the following ping command.
C:Usershitesh>ping yahoo.com -l 1492
Pinging yahoo.com [220.127.116.11] with 1492 bytes of data:
Request timed out.
Ping statistics for 18.104.22.168:
Packets: Sent = 1, Received = 0, Lost = 1 (100% loss),
If you see the above snippet, we see that when we try to ping yahoo.com with 1492 as the packet size we see 100% packet loss. I tried changing the packet size to 1400 and again pinged yahoo.com and it worked so i changed the MTU to 1400 inside router configuration and it worked 🙂
