Re: Connection dropping multiple times a day.

I am having major issues with my internet over the past few weeks. My Hub 5 router itself stays on the solid white light, then the cabled and wireless connections all drop off at random times. After about 5-10 minutes(ish), the Hub 5 flashes red multiple times, goes back to white and all is connected again. I keep getting many many many T3 timeouts on the router logs (I copied this from other post because this exactly what is happening to me).

Over the past month or more the page with services and outages was always saying there's a problem in my area and it will be fixed in 2 days. It never have been fixed and the same message has been displayed every day with different fix day. That issue "was resolved" a week ago or so, except it wasn't.

I've contacted Customer Service multiple times, the last time was on Sunday 15th when they said they will monitor my connection for 24 hours, at the end they said my connection is solid despite multiple drops.

It's like no one is capable to fix the issue, can anyone help?

    You still having issues ?  If so do this to get a "blank sheet" and theb report back an hour or two after doing it.

    ____________

    Switch the Hub off and unplug it from the mains supply for five minutes. Whilst it's off, do a quick check that all of your coax and ethernet cable connections are in nice and "finger" tight - at the Hub and wall box and also at any connectors etc. Ensure there are no “unterminated cable loose ends. Disconnect all the connections and reconnect to be sure. Also check that the internal wiring is ok with no kinking or chaffing. Check that all looks good with the outside cabling and wall box (no “staples, etc.,) piercing the cables. Then switch the Hub back on and leave ~5 minutes When all done, check back in the settings and ensure that the RS error counts and T3 errors have all reset to 0. Then check every hour or so to see if they start reappearing - they shouldn't. If they do (particularly the postRS and T3 ones) you have a problem (noise) that only a Tech visit will sort.
    Also check the Upstream QAM’s are all at 64
