Sky Fibre Max

markwilliams82 · 30 Jul 2018 at 21:25

Evening all - I recently joined Sky after moving into a house with a communal drive that prevented me from bringing VM with me.

I took out Sky Fibre Max so I can get speeds of 67MB

On my setup I have a NAS connected via cable to the Sky Q Hub and wireless I have my PC, nVidia Shield, PS4 and TV etc.

Recently I've been suffering a lot of loss of connections, especially on the Shield to the point any films I watch from the NAS will constantly buffer (had no issues previously when on VM) and the Shield itself will loose internet connection

Below is a copy and paste from my routers log.

Seems to be an awful lot of lease renewed 3600 errors - is this normal?

I read on a Sky forum that the number of lease renewals received will cause lose of internet connectivity, which will look just like a DNS failure. The lights on the router will remain lit correctly but all traffic will not flow to the cabinet/exchange

Lease renewed just means that the device has renewed its IP, 1 hour is a very short lease time though, you should be able to change that on the Sky router under the DHCP section to something more sensible like a day.

pepp77 · 30 Jul 2018 at 21:42

Lease renew of 3600 is normal on Sky Fibre, and there is nothing changeable on the router (at least not that I can see).

My logs look exactly the same and my internet connection has been up and stable for 563 hours.

markwilliams82 · 30 Jul 2018 at 22:00

Strange - never had issues with the Shield so not sure why I'm having an issue with buffering and drop outs now

Wondering whether I should try power line kits?

andicole0 · 30 Jul 2018 at 22:08

Streaming from a NAS should have nothing to do with your Fibre speed but your connections from source to display. Could try different ports somewhere?
Andi.

markwilliams82 · 30 Jul 2018 at 22:17

True but the NAS is connected to the SkyHub and wirelessly to the Shield whilst I get error messages on the nas that internet connection is lost and playback stops in worst case scenarios

andicole0 · 30 Jul 2018 at 22:23

So it's the router part of the hub not your Internet connection.
Andi.

markwilliams82 · 30 Jul 2018 at 22:31

I don’t know, that’s what I’m trying to figure out.

Internet speeds drop considerably and network connectivity on the shield drops

rhysduck · 30 Jul 2018 at 22:35

What sky hub / router do you have?

Because lately I've been getting drop outs and shocking wireless performance with my sky hub!

markwilliams82 · 30 Jul 2018 at 22:40

Only had it about a month so I think it’s the Sky Q Hub

Caged · 30 Jul 2018 at 23:55

A DHCP lease of one hour and checking the time servers every two hours - that's a chatty little box isn't it?

michty_me · 31 Jul 2018 at 08:11

A family member recently upgraded from one Sky package to another which resulted in them receiving a Sky Q hub. They are reporting the same issues as you are seeing. I've looked online and it seems a fairly common gripe with the new Sky Q hub.

Do you know if they still have the issue or have been able to fix it?

Last time I was around there, I tried changing the wireless channels and I think split the 2.4Ghz and 5Ghz channels. I'll check with them and see if they are still seeing the issue and get back to you.

No dice unfortunately. His Samsung phone constantly drops out, his PS4 drops out, can't share play, upload speed is around, ping hitting 300+ms.

Speeds are crippled to 1000kbps/600kb/s on a 34/8 connection.

Ill need to go check the logs and see what they say. His could be faulty for all I know.

No problem. I'll be sure to update if I get any further with it. I've stuck a post up on the sky help forums too.
Quite a few threads to read up on people with similar issues.

I've just had a quick look in the broadband board. There are loads of threads on very similar issues.

If you haven't already done so, have a read of this thread and the post from PDAVO123. I'll give this a whirl tonight.

Hi Mark,

After speaking to my relative yesterday. Apparently they have not seen any drop outs yesterday after I have changed a few settings.

Firstly, I logged into the router.
Unchecked the box for joining the 2.4 and 5Ghz channels (can't remember the exact name of the setting)
Renamed the 2.4Ghz channel so it totally separated it.

I then went into the Sky Q TV box and mini TV boxes and performed the following.

select home button on remote
scroll down to settings
now type 0,0,1 then select for a hidden menu.
go to network
at bottom you see 5GHz channel 36 / 80MHz
change this to channel 36 / 40MHz and save

One final thing that was suggested to me was to make sure you were actually connecting to the routers WiFi and not the TV box WiFi. I'm guessing by switching off all the TV boxes then selecting your network.
