If you are experiencing slow or erratic speeds when using a Linksys router it may be the MTU setting. Some Linksys models have an "Auto" MTU capability that does not function correctly and you must enable the "Manual MTU" function and manually enter 1492 (or less). To isolate whether the Linksys is causing the issue you should remove the it from the network and retest after conecting your computer directly the the modem.

Very Important Notes:
•Due to some operational issues it is VERY important that you have the latest firmware on your Linksys router. Please to the Linksys Download Website and ensure you have the newest firmware.
•When you set your MTU you must make sure the MTU is identical on all PC NICs and your router. To find your optimum MTU please click here.

Step 1
Important note: The following screen shots are based on a Linksys BEFSR41v.2 router and your screen shots may be different, however the steps and configurations are the same. Open a browser session and enter "192.168.1.1" in the address field to access the Linksys Interface. At the Username and Password prompt enter "admin" (without quotes) in the Password Field.



Step 2
Click on the Advanced tab from the menu.



Step 3
Select the Filters tab and find MTU. Select "Enable" or "Manual"and enter your MTU in the text field. Click Apply. The router will restart with the new settings. Remember, your menu may be slightly different but the overall process is the same.



Step 4
When you receive the confirmation pop-up click on Continue.



You're finished.
