Re: AC1900 and CM500 speed issue

Hooked up to Comcast/Xfinity that tells me I should have up to 300Mbps, but using wireless very close to the modem & router any speed test maxes out at about 80 (using both my windows 11 laptop and galaxy s24+ phone)
Is there some setting in the modem &/or router I should look for to speed things up?

WiFi speeds are mostly in the hands, or chips, the WiFi client. For some devices. 80 Mbps is all you'll get at 2.4 GHz. Neither of those two should feel that effect, but I'd look at see that they are using 5 GHz.

How are you measuring the speeds? What do you get with a wired connection?

You can check to see if there is any local interference that clashes with your router.

If this is a new service from Comcast, you could reset the router and set it up from scratch. Or take it through the Internet setup wizard to ensure that it is set up to fit in with the new service.

You should also know that the R7000 is an ageing (2017) router that is several generations behind the latest WiFi. It was a pretty good basic router in its time, bit speed freaks will have moved on to something newer.

Just another user with time on their hands.

Not new service.
Don't recall ever having a speed over 100Mbps even since we were "upgraded" to 300Mbps.
No wired connection available- silly new laptop is wifi only, and of course no wire on the phone.
Phone is airplane mode with wifi on.
Use comcast, google, and ookla tests.
Understand the router is "old," but throughput shouldn't be degraded from 600 to 100Mbps, should it?
Almost seems like I'm 'throttled' at 100... 😕

Borrowed a laptop with a wired port, and same 300 limit.

Here's the interface:

What speeds do you see with a ethernet connected PC or laptop connected directly behind the CM modem, with out the router connected?

BillGeddes · ‎2024-11-04

Looks like a gig, eh?

FURRYe38 · ‎2024-11-04

So what speed to you now see with a speed test app like Ooklas installable speed test app with the PC connected directly to the modem, with out the router connected?

michaelkenward · ‎2024-11-04

LAN3 (your only wired connection?) seems to be connected at 100 Mbps.

This is usually down to the device plugged into that port. Most PCs and laptops will have 1000 Mbps LAN support. Older ones and many other devices, such as TVs and printers, are stuck on 100 Mbps, which is fast enough for most kit.

A good item to have in your kit is a USB to Ethernet adapter. Choose the one that has the connector that matches the port on your laptop. Depending on your phone, it will also work there if you choose the USB-C type.
