Internet very slow early in the morning

My partner is a habitual early riser, and is usually online from about 03:00 onwards in the morning. Until about 07:00, she complains that her WiFi internet is frustratingly slow to non-existant, although during the day and evening we get around 10Mps wireless, and 30 mps wired, on a fibre connection. Location is near Sandwich in Kent. I have tried various alternative DNS settings, but the problem seem to relate to the time of day, not the equipment. Is there any reason why the internet would be throttled in the early hours, as contention is unlikely to be a problem? Would a new router help?

The most likely cause of this is not the router (although not impossible), but far more likely WiFi interference.

 

Slow speed, intermittent dropouts, breaks in the signal, or no signal on some or all devices, might be caused by Wi-Fi interference from other local networks, which can also lead to a permanent reduction in speed. No ISP can be responsible for your local environment, this is mainly a by-product of the popularity of Wi-Fi.

However, other factors should be investigated first. When this happens, what are the lights showing on the front of the router? Do you have any wired connections & if so, how do they perform?

If you have the HG633, HG635, DSL-3782 or the TalkTalk Wi-Fi hub, they are dual-band routers & offer both the older 2.4GHz & the newer 5GHz Wi-Fi bands. The problem is these are two different networks (SSIDs), but they share the same name, so you can't tell which one you are connected to. Log into the router (http://192.168.1.1) and enter a username of "admin" and if the HG635 a password of "admin" as well, or if the HG633, DSL-3782 or the TalkTalk Wi-Fi hub, use the unique router password (see the label on the rear of the router at the top).

HG633/635 go to:-
"Customise my wireless network"

Append "5G" to the end of the network name of the "Wireless 5 GHz SSID" field. Then click "Save".

DSL-3782 go to:-
Settings > Wireless (Wi-Fi)

Append "5G" to the end of the network name of the 5 GHz "SSID" field. Then click "Save".

TalkTalk Wi-Fi hub

Go to:-
Dashboard > See Wi-Fi Settings > Manage Advanced Settings > Wi-Fi 5Ghz gear icon > Basic

Append "5G" to the end of the network name of the "SSID" field. Then click "Apply".

This will not fix your issues, but it will make it much easier to identify the band you are connected to. This way you will know which band is causing your problems.

Generally speaking, the 2.4GHz band suffers much more from interference than the 5GHz band, but the 2.4GHz one can sometimes have a better range, but this all depends on your local area.

You may then wonder what was really the point of this if it won't solve the problem? This is because the whole topic is too complex to be dealt with in one post. The next stage involves sending out a guide to you to help you get me some important diagnostic results, so as I can analyse them for you and recommend changes to your router configuration to solve them.

I only send this out to people who request it.

Hi Keith, thank you for that quick and helpful response.

 

I will check out the situation with regards to the lights on the HG633, and also do a comparison of wired v. wireless, tomorrow morning, and get back to you. As suggested, I hace also changed the SSID of the 5G field.

Hi Andrew

 

Please let us know how you get on.

 

Thanks

Good Morning Debbie,

 

The advice was very helpful. By distinguishing the 5Ghz band, we were able to establish that we were not actually using this, and switching to it has increased the router speed enormously.

 

I had been under the impression that the selection of the best band would be automatic, and although both were are operative, without differentiating the SSID between them, there was no way to tell which is being used.

 

Thank you both for your help - fingers crossed that is the answer!

Hi Andrew

 

Thanks for keeping us updated 🙂

 

Keith provides really good advice on improving wireless performance.

 

Please let us know if you do experience any further issues.

 

Thanks

Hi keith, Thanks again for your very helpful reply. I wasn't aware that you had to manually select the 5Ghz band - I thought it was automatic - and that has improved things a lot.

 

You mentioned a guide in your note, and I would be interested in receiving this, if only to improve my own knowledge of the subject!

 

Regards,

 

Andrew

HI Andrew,

 

No problem, if you decide you do want my help, please just read this next bit:-

 

Please see my attached guide on Wi-Fi interference & initially look at the section called "Are you suffering from interference – prove it first". This section includes full details of Wi-Fi analysers that I recommend for Windows, Windows phone & Android and Apple operating systems. However, I have no way of testing the Apple product. Do not worry about interpreting the results, I will do that for you.

Please post the screenshots that I have requested in my guide, from the analyser you are using (also in my attached guide). Please ensure that the analyser is maximised (if Windows) before taking the screenshots & upload them via the "Photos" button on the post editor's toolbar as large images. If they are too small, I will not be able to read them & although I can enlarge them, this just puts the text out of focus. If you prefer PM them to me. If you do PM me, then please add a link in there to this thread, so as I can find it easily.
