I am experiencing slow internet connection. This week I upgraded my connection to 50/10 but when I run speedtest I am only getting 10/5 (which was my old speed).

 

These are some of the commands I've run:

 

sh int e0/0 

Interface Ethernet0/0 "", is up, line protocol is up

  Hardware is 88E6095, BW 100 Mbps, DLY 100 usec

Full-Duplex(Full-duplex), 100 Mbps(100 Mbps)

Input flow control is unsupported, output flow control is unsupported

Available but not configured via nameif

MAC address ccef.4892.00a8, MTU not set

IP address unassigned

32743950 packets input, 10427010137 bytes, 0 no buffer

Received 736 broadcasts, 0 runts, 0 giants

473249 input errors, 473249 CRC, 0 frame, 0 overrun, 0 ignored, 0 abort

0 pause input, 0 resume input

0 L2 decode drops

17 switch ingress policy drops

29573839 packets output, 22522013226 bytes, 0 underruns

0 pause output, 0 resume output

0 output errors, 0 collisions, 0 interface resets

0 late collisions, 0 deferred

0 rate limit drops

0 switch egress policy drops

0 input reset drops, 0 output reset drops

 

The command below gives me a lot of information, but I really don't know what I am looking for here.

So reading an article on input error and crc where one of the reasons for the high number of errors and crc was that duplex on the asa was set to full, while the modem/router was set to auto. I changed all settings from full to auto on all ethernet ports. And now I have 50/10.

 

Thanks to anyone who contributed with comments on this problem. Much appreciated!

Hi, What is "Interface Ethernet0/0" connected to? Were interface counters cleared after the upgrade? Thanks John

E0/0 is connected to the "modem"/router. I did a clear traffic after the upgrade, but don't know how to clear other things.

I took one computer out of the network and connected it directly to the modem/router and it got 50/10, so there is something wrong somewhere.

Interface e0/0 is the outside. So it is connected to the modem.

Here are the same stats some hours later. I shall see if I can clear the interface counters

This is after the clear interface ethernet 0/0 command and after running some 2 minutes or so
