Very slow wifi speed on all devices, but speed test shows fast

Is it a coincidence there are AA adverts on the TV the night before your car breaks down?

If your inbound speed is below the guaranteed minimum then report it as a likely fault for investigation, otherwise Sky won't know there's anything to 'sort': the vast majority of such problems are caused by external line problems and require resolution by Openreach.

Don't know if this will help anybody but.........

We recently upgraded to 80mb Fibre from ADSL broadband and were getting very good response on all devices. Yesterday it became very sluggish and doing a speed test on a laptop showed speeds around 35Mbit which was disappointing to say the least.

Logging into the Router showed that it was connected at 79mb down and 20mb up and on the laptop showed a connection speed of nearly 100mb onWiFi but the speed test was only 35mb.

Further investigation showed that the Router had upgraded firmaware installed 8 hours before and that the WiFi connections to the devices were only IP4 and not IP6 as usual. So I tried rebooting the laptop and hey presto - fast connection again and a speed check got me 73mb which I am happy with.

@another-user-name A device connecting by IPV4 or IPV6 has no bearing on throughput speed whatsoever.

100Mb link speed is typical of a slower 2.4GHz connection. I suspect what happened is the device in question connected via the 2.4GHz wifi band when the router updated firmware. Then when you manually rebooted it, the device(s) in question have connected via the 5GHz band instead. 

FTTC connections are always usually much quicker than ADSL, which is an old outdated connection type from the 2000's and is woefully antiquated for todays usage requirements.

The only purpose for posting what I did was to show some of the symptoms I found which appeared to throttle the WiFi connections and it seemed to be the same symptoms as others had experienced. I have no idea why rebooting the laptop actually fixed the problem, but it did and the IP6 connections reappeared on the router so it must have changed something important.

Hopefully other non technical people will appreciate my non technical suggestion.

Three days now of slow download speeds on a computer (via ethernet) and constant buffering on streaming services (again on ethernet cable.) 

So far this year we've reported the problem to Sky 3 times, and each time it's 'fixed' and everything is fine for a couple of months.

Fed up to the back teeth with Sky now.

I have also started getting really slow wifi speeds, with the Sky broadband 203 router, I have checked everything from rebooting to changing channels but this only made things worse, I even shut down all the devices on my network including sky q boxes to rule out hotspot issues bu the problem was still, I was getting 79MB sync speed to the router but only 2.5MB download and 0.25kb upload on my normal wifi connection on an average day you would normally get around 25MB Download and 17MB upload, I used ISSider to see who was using what channel in my area and there was nothing that I could see that would be causing the wifi issues there are several houses within our area who all have broadband and we all tend to use channel 1, 6, 11 with 20mhz spacing so as not to overlap each other and both myself and our neighbour use opposite  channels by agreement, I resorted to performing a factory reset on my broadband router yesterday but it made not diffrence the speeds were still extremely slow using wifi, I ended up by remiooving the the Sky hub and replacing it with my backup router that has been used with other isps over the years a Netgear D6400, It has never let me down yet and guess what it worked perfecley giving me back full wifi speeds, I think that there are issues with the way that the sky router works and does not perform as well as other routers in certain conditions.

When Q boxes are added to the equation then yes, unfortunately I suspect that's quite possible.  As I've frequently observed, Q television was always intended to use built-in Powerline networking as well as WiFi, so in its current form it's missing a designed component.

Lately my connection speed dropped a lot. I eliminated the WiFi issue by using ethernet cable and even after reboot my connection speed is around 3.6Mbp/s CRAZY !

It is supposed to be fibre super fast connection ! I am getting better speeds by tethering mobile phone.

If you will try to call the support you will waste so much time waiting and then going through some basic script tasks - when you are working in IT it is really annoying. I have been with SKY for more than 10 years and the connection speed was better when I was on ADSL+ and It was much more stable (1 maintenance a week around 1-2 am on Tuesdays or Wednesdays if I recall correctly).

Can you post you router stats

I'm having problems with speeds on internet.. I'm living In the Hse 2 &  half years, never had this prob b4.. I use 2 different apps on phone to test speed, the speed is that low at times even they can't connect to measure the speed.. isn't it amazing that when u complain to sky about ur speed, they are very forthcoming at selling u a guaranteed speed if u pay the extra each month.. I did have a guaranteed speed of 32 to 60 mps.. at times can't even get 2mps.. sky sound very familiar to APPLE SLOWING DOWN  PHONES.. which was proven!! Or VW / AUDI  FIXING THE EMMISIONS ON NEW CARS.. also proven.. sky claim I'm getting 72mps to my Hse .. joke.. they are totally in denial, I've had a few debates with sky over the phone.. to no evail.. when contract is finished, so is sky.. I wouldn't touch them with a barge pole.. & IF EVERYBODY LEAVES SKY .. THEY GO BANKRUPT..  HELLO BT

@Stephen196 You use 2 different apps on your phone to test speed.....well there is your issue, WiFi, not the actual broadband connection itself, as they are 2 different things.

Sky are "claiming" you have 72Mb as that will be what your router will be connecting at, it isn't a lie. The speedtests on your phone are testing something else which is an extra part of the chain, which are a lie because they are not telling you what they are measuring....

You are testing the speeds over WiFI. This isn't guaranteed. Any speed guarantee with any ISP is for the speed between the street cabinet/infrastructure to your router, not what you recieve on a device connected via WiFI.

I am having really slow speeds the last few days. Here are my router stats. Any help greatly appreciated. Thanks

• As this is fibre to your property you need to test the connection speed with one of the many speed tests via ethernet direct to the router with nothing else active at the time of testing.
• The usual Sky health check cannot access your incoming speed, they would have to check that with OR.
• If as is most likely you are reporting slow WIFI then the usual caveats apply.

[Shallowhouse12]

Many thanks for response. Sorry to be thick. I need to connect a device to my router via ethernet cable and do a speed check like that? 

[TechmanagerMal]

• @Shallowhouse12 You are currently testing speed over WIFI so in order to get nearest to a result for your access speed, you need to connect an ethernet-capable device ie a PC or Laptop directly to your router and then run a speed test.
