Wi-Fi gradually slowing down then crashes completely, multiple times daily.

[Poyle]

Hiya, 

I'm having an issue here with my Wi-Fi/Broadband - I am using the Superfast package. This issue occurs multiple times daily and is most common in the evening. 
What happens is that the internet speed will gradually slow down over 5-10 minutes until it finally crashes completely. Afterward, it will reboot by itself but it will only be putting out speeds of around 2-10 Mbps. Rebooting the router usually resolves the issue, but only very temporarily. As after half an hour, the exact same issue will happen again. On a good day, I will be getting speeds of about 50-60 Mbps, on multiple devices. 

To rule out a few things;

My broadband hub is on top of a counter, with nothing immediately surrounding it, and no other devices are close to it, and there have been no line faults detected.

My router stats are posted below. Any advice would be greatly appreciated.
Thanks.

Stats look fine (actually very good) so getting Sky to swap out the Hub would seem appropriate.

At the time of screenshotting your stats you were using practically all of your bandwidth as there is a LAN device using 64mbps. Are you sure the symptoms you are experiencing are not just a device downloading at full speed and leaving no bandwidth left for anything else. The Sky Hub has no form of QoS so contention is possible.

Is the rx figure bytes per second or bits per second

[jamesn123]

@cookiemonsteruk 

I always assumed bytes but perhaps it could be Bits

[cookiemonsteruk]

@jamesn123 

Always took it as bits per second or the wan figure  would be impossible

[jamesn123]

@cookiemonsteruk 

True.

According to Wikipedia, which I am not sure I trust at all, Bits Per second is shortened as bits/s and Bytes per second is B/s. So not sure

In the op they say they're getting 50-60Mbps and wan rx is 24Mbps leaving 56Mbps is how i have always read it. Now i am not to sure

@cookiemonsteruk 

Absolutely correct, the WAN is transferring information when stats were taken at 24Mbits/s leaving plenty of capacity...

[cookiemonsteruk]

@jamesn123 

But then again they say it crashes down to 2-3Mbps

@mae-3 rx bits per second or bytes per second on the wan

[mae-3]

@cookiemonsteruk 

rx is in bits per second on WAN...

[cookiemonsteruk]

@mae-3 

You answered my question before i asked it 👍

[jamesn123]

Interesting, I always look at the LAN & WiFi figures separately so never really noticed the WAN Rx figure was over the line speed.

Never been a fan of the use of shortenings like b/s as it isnt clear what unit is being used

@jamesn123 

When i started on the forum i remember @mae-3 quoted the download speeds on the wan and always wondered how he knew.  Guess i figured it out and it stuck 

[mae-3]

@cookiemonsteruk & @jamesn123 

b/s goes back to the old days of serial RS232 communications connected to a modem which were expressed as two states, 0 and 1 for a bit and transferring information in serial format and is done in bits per second always when over anything but a parallel interface which is in bytes.

Does anyone remember 300 Baud modems?
