Slow WiFi when neighbors

[SylviaSylvia]

Hi,

I've got problem with my WiFi speed, but only when my neighbours are home. We live in the block of flats, and only when neighbors from downstairs are home and watching something, our WiFi is really bad (download 0.5Mb to 0. I tested my connection on talktalk website and it says that to the router is good (45Mb). I restarted and rebooted my router (Huawei HG633) and it helped only for 2-3 minutes (download 30Mb). I've tried changing channels on router and nothing. There is only 2 phones connected to our WiFi. 

When neighbors are away, all WiFi is good. They've got BT connection and they don't complain. 

Only ideas how to fix this issue?

No problem at all @SylviaSylvia, glad to help.

Hi @Karl-TalkTalk 

Done.

Hi @SylviaSylvia 

Can you please add your home phone number or Account number to your Community Profile. 

We will not attempt to call you, this is so we can locate your account and run tests on your line if you are reporting a fault.

We will then reply via this thread in our Community with any further advice or next steps.

If unsure of your phone number, and if your line is working simply dial 17070 from your land line phone and this will confirm the number for you.  Alternatively these details can be found within My Account online or may be on the heading of any paperwork you have received.

Please post back on this thread when this has been done.

Thanks

Karl.

Hello @Michelle-TalkTalk ,

Yes, send it to me, please.

Morning,

Would you like us to send a replacement router for testing purposes? We would also send a router returns bag so that one of the routers can be returned.

Thanks

Please find attached traceroute files. 

Thank you Keith for your help. You are real community star.

I think this HG633 has an intermittent fault on it, please can it be replaced?

[KeithFrench]

I have been doing some diagnostics checking for WiFi interference via PMs, but there isn't any. Perhaps this is a network issue, I have asked the customer to produce some trace route output to an affected website when this next happens & report the findings here.

Hi SylviaSylvia,

I can vouch for Keith, he and his guide have helped many customers. However it is entirely up to you if you choose to accept Keith kind offer of assistance 🙂

Hi @Karl-TalkTalk @Debbie-TalkTalk & @Michelle-TalkTalk 

This customer @SylviaSylvia does not want to use the download link I have PM'd to her for my guide, as she doesn't know me. I can easily understand her concerns, so please can one of you vouch for me so that I can try & help her?

[KeithFrench]

I will PM you a link for a guide of mine 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 (no photos please they can be difficult to read as text can get out of focus when zoomed in), from the analyser you are using (also in my attached guide). Please ensure that the analyser window is maximised (if Windows) before taking the screenshots & upload them via the "Insert Photos" button (in a mobile browser it's the picture icon) on the post editor's toolbar with the Size parameter set to Large. If they are too small, I will not be able to read them & although I can enlarge them, this 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 that I can find it easily.

Hi @KeithFrench ,

If you could send me that guide, I will be grateful. 

@Karl-TalkTalk thank you for your reply as well (no reply button in your post)

Hi @SylviaSylvia 

Slow speed, intermittent dropouts, breaks in the signal or no signal on some or all devices or no internet access 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 byproduct of the popularity of Wi-Fi.

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.

The next stage involves sending out a guide to you to help you get me some important diagnostic results so that 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

If there is local wifi interference, this can be difficult to troubleshoot.

If you have an android phone, there are some free apps such as wifi analyzer that can show the wifi signals around you, and the channels in use to help you choose the least congested channel to see if this improves performance.

Thanks  

Karl.
