A problem

Might check a web site, put tracert somesite.com in a Command Prompt or PowerShell window to check where it's going to get to where the information desired is. The biggest issue with speed is all the junctions a signal has to make and the number of users connected affecting the bandwidth. Those of us that were back in the Dial-Up days experienced slow speeds that actually were normal for the times.

Don't complain. Here in Greece before VDSL broadband connection was available maximum ADSL speed was 24Mbps but hardly anyone got it. The average speed was close to 10Mbps. Only with VDSL and recently with fiber we have close to the nominal speed (30, 50, 100, 200). If we had 300 right now we would celebrate it!

I had to touch the coding gain and change that to "7" on my BEC 7402TM router, back when I had ADSL, last in 2013. Just to get it past 10 Mb down. I then started getting 13 and 14 Mb down, possibly hitting 15 Mb down. Definitely wasn't going to get 24 Mb down.

Even worse, in the dialup era, a 56K line rarely hot over 40Kbps. I remember any picture of a website slowly appearing line-by-line. Today's websites would need half an hour only to open the first page. If you dare click on anything, you would have to wait another half an hour.

As for complaining, it depends on what speed was purchased and the advertised speeds since with XFinity, if things work correctly, almost everyone gets the advertised speeds which is always what is advertised and up to 20% higher than the advertised speeds as they usually overprovision everything by 20%. I am on a XFinity 1.2Gbps/35Mbps connection and everyone gets 1.44Gbps/42Mbps without issues as seen on dslreports. These are my speeds for example:



Provisioned speeds are seen here:


56k modems are a different issue as that depends a lot on the switches used which can include the Nortel DM2000 and the Lucent 5ESS and also the modems used on the other end. As a ISP, we regularly get people with 45kbps-49kbps. Transfer speeds are a different issue because a PRI which is 1.536MBps or a T1/DS1 consists of 24 modems with one line used for signaling so it may not be available but then what also matters is the amount of bandwidth from the ISP itself to the uplink and the bandwidth is not oversold. XFinity/Comcast owns their own tier 1 backbone. Sometimes the issue can be the computer or something else, that's why it's better to test directly from the modem without any switches involved and also try a different computer using the same test.

One other thought that comes to mind is what modem are you using and do you know if the boot/config file is for the speed you are paying for assuming you have a modem that supports the speeds you are subscribed to.
