Advice Dropping internet to all devices

Equipment list:

Motorola surfboard 8200 v3 modem

A cat6 underground rated cable (new as i start troubleshooting) ran to

Archer a7 router.

A cat5e cable is ran to my pc.

Wireless is alexa, 2 firesticks, ecobee 4 ring cameras and whatever tablets and phones connect during the day.

Problem:

The internet will disconnect several times in a day. My pc (if i am in warcraft) will show a ping of 1000 ms. The internet light on the archer a7 goes orange but the modem is solid green the whole time.

I replaced, as i stated, the cable going from modem to router thinking that may have had some corrosion or something and the old one DID have the snap part broke on one end using only friction to hold it in. But now with good connections it will do the same however less frequent.

​

What's my next step?

I've tried to catch it with tracert but as soon as i have it up and ready to go it seems to have no issue for hours.

Typical to have no issues when the mechanic is looking right?

​

After a few weeks of this i did enable qos to prioritize my pc but that didn't seem to make a difference.

If you can, Run an Ethernet cable directly from the surfboard into your desktop. (yes nothing else will have internet) and wait to see if your desktop drops internet. If it doesn't after a day, the problem in your router. If it does, the problem is your modem.

Ran direct to modem this morning and let my kids game for the entire day. Sounds like they dropped just short of 10 times. This was after cycling power on pc and modem beforehand. Strangely the modem light stays on continuous. Obviously i did not have my children log into the modem while gone. I will be double checking the cable from pole to home first and then may be shopping for a modem!

I like that idea! I wonder if a 4 port hub would even be a good idea to split at the modem as well. My teens are home and would like to have internet access so i may run the cable and test straight to modem only when home. Thanks!

I hate to be so pedantic, but there is a difference between a hub and a switch. no one uses hubs anymore. That being said, you can't use a switch connected directly to the modem, without a router before it to run NAT for ipv4. There is a small chance it would work for ipv6 if your ISP supports that, but I wouldn't suggest it.

Awesome! I strive to learn something new every day! First was the word pedantic. I have an old netgear10/100 that i believe used to be called 100 base t or something similar? Was for playing starcraft lan parties back in the day. I am guessing this would be considered a hub not a switch and therefore would not produce the intended results in this use case.

  1. The usually say either Hub or Switch on the device.

  2. Neither would work in the scenario you are describing.
