Hi.
I've never put it in modem mode as I don't have a spare wireless router in the house and I am not paying for a new one and my family won't let me do it because we've got a lot of devices dependent on Wi-Fi (4 Amazon Alexas for a start) so we need the Wi-Fi up.
All ethernet ports are occupied as one goes to a small powered 1GB 4 port switch (2 Lan Users on here), and the others to the TV , Virgin TiVo Box and Video Doorbell.
It's exactly the same set up as before and it's not related to LAN as the Wi-Fi Laptop users (the wife) will complain that the Internet is down again.
Every cable has been taken out, checked, replaced and put back as I have spare Coaxial and ethernet cables.
This morning I got up it was slow. so I did a speed test - 0.12Mb Down, 20Mb Up. Started typing this comment and 5 minutes later did a speed test, this time 40Mb Down, 20Mb up, but it found a different server to use on speed test. Reloaded the page, did it again 1 minute later 1Mb Down 20Mb Up.
Have just rebooted and expect it to be fine a minute or two - yep 200Mb down, 20 Up.
I'm just wondering why we was offered this "upgrade" in the first place as the Hub 4 did everything that the Hub5 does.
We don't move vast amounts of data around our network and I'm the only "heavy" user and my network card is a 1GB so why do I need a router with a 2.5GB ethernet port?
Oh well, maybe someone has an answer short of replacing the router.
