Sky Q Router - Ethernet speed drop - wifi fine

Sometime yesterday between 8am & 7pm the Ethernet speed to my PC dropped to 9mbps and stayed like that until I rebooted the router.

What doesn't make sense here is that the WiFi speedtests conducted yesterday and this morning showed no loss of speed, yet the wired test to the PC showed a drop from 36 to 9mbps.

Coincidentally between 9.15am and 12.15pm I joined the 21st Century and had Sky TV installed.The sky engineer did not touch the router and when connecting the Sky Box wifi, I pushed the WPS button.

I've only been with Sky Fibre 4 days.

Any info would be great to receive.

Done a bit of guesswork as the fault continues and everyone seems to have wifi only these days.

Spoke to a guy at Sky who checked out the router and found no issues, so he said it must be the cable and is sending out a new 2m cable to me. In the meantime, I swapped the cable into the other port and speeds were back to normal....

I also have turned off the 5ghz wifi as I don't have any specific 5ghz band devices. Here I note the router now runs much cooler.

I'll see what happens in the coming days as to whether the drop in wired speeds occurs again. I'll also see what Cat the cable Sky send is, current cable (15m long). I had no problems with up to 80mbs on previous routers, before future proofing the home with Cat 6a STP, whicih I know shouldn't be necessary..

It does sound as if the Ethernet connection is dropping down to 10Mbps connection speed instead of 100 or even gigabit speeds. This is usually caused by a faulty cable or a faulty Ethernet card inside the computer.

It could also be an driver issue of some sorts. Any recent changes to the computer such as the OS?

Been running Ubuntu Mate for 8 mths, no problems until this router. Computer is no more than 13mths old only had Linux Mint & Ubuntu Mate on it.

If I've understood correctly, you have a problem with one of the ethernet ports on the router, but not the other? Could be a hardware failure on one of the ports, I've had that happen before on a (non-Sky) router.

You might be right!

It was port 2 that went slow on all 3 occasions. I'm now connected to Port 1. If this port does not go slow, then I will swap back to Port 2 and see if that drops after 2 days. If it does then that would indicate a port fault.

I assume then as the cable works fine on port 1, it is the router and request a replacement from Sky.

I've had Ethernet port 1 fail on two Q routers.

I've just removed my skyq router due to slow wired throughput, put my asus back in and slow issues gone.

are all of your other skyQ and sky mini services also working with your router?

Port 1 is working fine. Will try Port 2 again and update in a few days time

The SKY Q router is the worst router I have ever had! Wireless = speeds at 20mbs less than previous sky router. Plus this router has just 2 ethernet connections instead of the usual 4. A cheap router with cheap functions and cheap connectivity and this is what we pay SKY for?

Kindly let us know how have you set up your Asus Router to work properly with Sky Fibre ?

I am presently using the supplied Sky Q router for most Ethernet and wireless operations (including the modem, NAT and DCHP) and I am presently only using my Asus DSL-AC68U router as an additional 5Ghz wireless connection as I find that the 5Ghz wireless on the Sky Q router, (which for some bizarre reason is locked onto channel 36 which is the channel that most neighbours will be using), is unreliable.

Therefore, under my present setup, I am effectively just using my Asus DSL-AC68U as just a 5Ghz Wireless Access Port which is a something of a waste as the Asus DSL-AC68U is excellent router but when I tried to use it fully instead of the Sky Q Router I had a few problems setting it up and had decided to put it in the back burner for now.

I have previously set up Fritzbox Routers to work with BT and I was using my Asus DSL-AC68U with BT Infinity up to, (about a month ago), when I changed to Sky fibre and I am not sure what settings I should be using as it did not seem to work when I tried it. - I first used Wireshark to obtain the sky Username and Password, (I also tried spoofing the Sky Q Router MAC address but I do not know if that is needed or not), I had a good guess at the other settings and when I tried it did seem to connect but it was not useable as it did not seem to pick up the DNS and it did not seem to operate properly.

I avoided trying the quick set up menu in the Asus as Sky did not seem to be listed.

Kindly let us know; what settings you use for your Asus Router with sky Fibre ?

To use my Draytek equipment, I found that MAC cloning seemed to help, otherwise the new kit would never authenticate on the line (with my Wiresharked DHCP options 60/61 from my SR102)

I have moved home and back on the adsl2 service, but I had to use merlin firmware on my asus to get it working on Sky fibre, mine is the AC68U so I ised the BTopenreach modem then entered my details in to the merlin firmware, if you google "use own router sky fibre" there is a guide I followed on an asus that worked for me.
Also look up merlin asus firmware

Using the Sky Q router, at the front end as a modem and for most of basic routing/Ethernet/Wireless needs seems mostly to be OK well as it seems to be only the fixed to Channel 36 Wireless 5Ghz that is less reliable and using the DSL-AC68U as a Wireless Access Point does add to the mix a strong reliable 5Ghz wireless option and I see little benefit in using an Openreach Modem at the front end instead of the Sky Q modem/router.

To fully use both the modem and the routing parts of the DSL-AC68U I would consider using Merlin Firmware if there is no other way but I suspect that I will avoid doing that if at all possible.

I have previously considered using Merlin Firmware but I am reluctant to do so, (not that I have heard anything bad about Merlin Firmware, in fact the opposite is true), but Merlin Firmware appears to be a modification of the Official Asus Supplied Firmware and I am not comfortable using modified firmware any router, firewall or an anti-virus as there is always the very unlikely, very remote, chance of some sort of hidden back door. - (I have no idea if that is possible but it makes me uncomfortable).

Also, the my own DSL-AC68U Router is still under guarantee as it is less than a year old and it has over 2 years of the 3 year guarantee left to run which would probably be invalidated by none-Asus Firmware.

Does anyone know a way to set up an Asus DSL-AC68U to operate on Sky Fibre with the standard Asus firmware ?
