Internet Speed Performance on ADTRAN Unit

[Anonymous]

It's an Adtran 3448 with EFP.  Basically, I wanted to find out how to troubleshoot it.  How do I find out if the ISP is giving us the full speed they say they are?  How do I find out if the router is not performing up to speed?

Thank you for asking this question in the support community.  I recommend following the Troubleshooting Internet Speed Test Issues guide.

I hope that makes sense, but please do not hesitate to reply to this post with any additional questions.  I will be happy to help in any way I can.

Thanks Levi, That was exactly what I'm looking for.  Do you have any documents similiar for point to point connection?  point to point t1, point to point ethernet, etc?

I have previously run speed tests on the 3448 and it's maximum throughput is about 80Mb/s.

If you more rules in place looking at traffic it would obviously be slower.

The same concepts from the guide can be applied to T1 and any Ethernet connection. 

• Try using a different Internet speed testing website
• Connect the computer directly to the Internet connection or modem (if Ethernet), bypassing all internetworking equipment, and run the Internet speed test again
• Enable the RapidRoute “Fast Forwarding Engine” (FFE) on all of the ADTRAN unit's interfaces
• Make sure there are no errors on the ADTRAN unit’s interfaces
• Verify the ports are negotiated to the proper speed and duplex
• Disable Link-layer Discovery Protocol (LLDP) on the interface connected to the Internet, T1, or modem

Let me know if you have any other questions.
