Slow internet speed and spotty at times

Can't see your pics. Since you are a new poster, they need to be approved by a Forum Admin. That could take some time. In the interim, you could try hosting them at one of those free third-party pic hosting sites like Imgur or Photobucket and post the link to them here.

Or copy all of the text of the status page and paste it into the body of your next post here.

Thanks @EG , let's see if this works, if not I will use 3rd party for images.

Internet is spotty and varyies in speed.

Spotty being, showing internet connection but no data transffered

Various speed ranging from 3 Mbps to 50 Mbps

We have the xifitiy blast that shold see up to 200 Mbps

Done a series of checks and looked at the downstream and upstream power:

Connected modem to direct line into the house bypassing the amplifier

Removed splitter

Changed cables

Modem : Motorola surfboard sbg6580

Any advice to help solve this would be great, it gets really fustrating during my internet calls (WebEx, Teams, Zoom...) for work

Connected to direct line coming into house

With Amplifer and 2 foot cabel

This is after the series of checks I did

Event log

Still can't see them. Do what I suggested in my prior repy.

I see them now. They must have been approved.

First. You can remove the amp. You don't need it. The signals are already too hot !! You may want to re-insert the splitter too to knock the downstream power down some more !

Second. Is this with a WiFi connection ? If so, for a test, does a computer / device hardwired directly to the 6580 with an ethernet cable have the same problem ?

With this test, we are trying to isolate this from being either a WiFi-only problem or a problem with the general connection to the Comcast system which would of course affect both. It's a good first step of troubleshooting before we proceed any further.

Still can't see the error logs pic.

Let's try it this way

Thanks  @EG 

The amplifer is Commscope CSAPDU9VP, and feeds living rooms and bedrooms with a coax cable. To be honest I've only recently moved in to this house so trying to understand the wiring and how to get the best out of it. What do you think it was used for?

Right now my modem and cable TV box are in one room - just using 1 channel on the ampifer.

All this is happening on Wifi.

I will hook up my laptop and confirm it is is also seeing the same issues, updates to come

Let's see if this even logs works

I have moved my modem to my office, and laptop is connect via ethernet cable.

had a huge speed increase , now around 160 Mbps

I will have to see if there is any decrease in speed and any intermitent drops.

Is there any other way I can check Wifi Vs hardwire?

It's mostly happening on Wifi, particularly our phones and laptop (FaceTime, Internet browsing...), and Internet TV's when were are streaming.

We have had the router for over 6 years so you can imagine the amount of devices that have been added to it.

@EGdo you think it's worth changing the wireless network name and password, and re add all the current devices?

I don't see a way I can remove the MAC addresses from the router?
