SR203 on FTTP - poor performance and other issues

Looking for other posters experiences with Sky FTTP (160/30) service, for those whom have moved over from the older FTTC over phone line.

Over the Christmas period I visited a friend whom was on the upto 76 Mbps Sky 'Fibre' FTTC service, with an SR203 router and the green box up the street around 450/500 metres away, typically getting 40 to 50 Mbps downloads. Four adults, SkyQ box on main TV, one mini elsewhere, and lots of other devices from Amazon, Samsung, Apple as you'd expect.

Openreach FTTP in the road, so they upgraded due to getting occasional problems downloading films on SkyQ, and poor WiFi. Openreach do the work, new ONT installed, three green lights. Same router, and Sky hadn't provided ANY instructions or cabling, (in fact, randomly a completely identical SR203 delivered with the FTTC splitter and RJ11 to BT jack cable) arrived two days later. Openreach installer luckily has an Ethernet cable on the van, so the service works. Using the 160/30 OR service, so speed tests on a modern Samsung phone next to the router achieve 150 down and 28 or so up. Great.

However downloading movies on SkyQ now occasionally fail, and sometimes the WiFi just 'stops' (samsung phones show no WiFi signal) until the SR203 is reset using the button on the back.

I wondered if....
a) Are there known faults with the SR203 and full fibre FTTP connections, where the Internet and/or WiFi lights go out, or is this a fault unit?

b) Before installing a 30metre Ethernet cable between the main SkyQ box and the SR203, is there any diagnostics in the SR203, or perhaps there is WiFi interference causing issue?

The Sky router has been in the same place (hallway) for 10+ years... slow but working well. The ONT always shows 3 green lights, unless we unplug the ethernet cable, there appears to be no optical issues.

Thanks.

I recently joined Sky, albeit on a FTTC connection. Wi-Fi performance is as good as any other router. Have they considered using wireless boosters?

Both my sons are on Sky FTTP using SR203s. I'm not aware of any issues.

Just taken a look by remoting in to both, Son 1 shows an 'up time' of 1332 hours, Son 2 is 420 hours (which correlates back to the day his living carpet was changed, so everything got unplugged !)

Both running 7.02.0203.R Firmware

Are you saying that when this problem occurs, one or more lights go out on your router?

If the wifi light goes out, it's almost certainly a faulty router. Nothing that a client does should affect whether the router serves wireless or not.

If the Internet light goes out, then it could be a problem with the connection - although if resetting the router clears it, then that points strongly towards a faulty router too.

Interesting to hear of your challenges with the SR203 on FTTP, as my intention is to use my existing SR203 when I switch over to FTTP (currently on FTTC, but FTTP should be available for me to order in the next few months).

Not sure if this may help, but a while back, I recall a post (could have been or here on another forum?), in which someone recommended that prior to using the SR203 on FTTP, it was worth logging into the router settings and changing the 'Router Mode' from 'Auto' to 'WANoE' (I guess this would be to force the SR203 from being in VDSL mode? The person mentioned that the Auto setting could be a bit glitchy, not always picking up the change from VDSL)

They have a booster upstairs, never needed downstairs. Rented from Sky (which I advised was something to think about stopping and buying a mesh, instead of a booster).

Thanks, good to know!

Not mine, a friend I visited over Christmas. (no Openreach FTTP in my town).

I tend to agree with you on the lights, which is why I was asking for others experience.

Useful tip, thank you!
