Slow internet speeds through 7301 router.

[cswallace1]

Hi all.   I just upgraded to Gig speeds through comcast. I am getting high 800s from modem straight to pc but low 200Mbps once I go through the router.  Not sure if the router can handle the throughput but could not find anything on it.  My question:  is there anything that I can configure on the router to increase the speeds or do I have to get a newer router??   My running config is below.  Thanks in advance.

Hello,

your 7301 is (obviously) an ancient device running outdated software, but nevertheless should be able to achieve a WAN throughput of +/- 1Gbit. You could make a few changes (marked in bold), but also post the output of:

sh interfaces GigabitEthernet0/0

Thank you for the quick response Georg.   I updated the Bold print and my speeds are now matching what I was getting without the router!!!
