Gig1 - 90Mbps without reboots

[Dan_F123]

Hi all,

Have spoken to several VM support agents about issues I'm facing with my Gig 1 service.

Unfortunately, for at least several months, the service declines from 600-800Mbps to max. 90Mbps. A reboot fixes it most of the time, but it soon reverts back to 90Mbps. Upload remains stable.

I am testing with a device directly connected to the hub in Modem Mode.

Apparently there's a note for the backend team to look at this issue, but I'm concerned that the issue has persisted for several months so far with no resolution.

Could you take a look at my downstream logs and let me know if there's an issue.

Many thanks in advance.

Want is the link speed when it drops to 90Mb? You cound connect a PC to the hub in modem mode and if its got another NIC use internet connection sharing in windows for testing.

If link speed is 1Gb then the hub internal link speed is faulty and you need a new one.

Hey @Dan_F123,

Welcome to the community and thanks for taking the time to post your issue on the forums.

I'm sorry to hear of the issues that you're having, I have looked into this and can see that there is an issue with your upstream power levels that will need a technician visit to resolve.

I can arrange the appointment from here but would need to confirm a few details via a private message, that I will drop over in a moment.
Please look out for the private message and we can get started.
