Wi-fi dropping and range radically reduced - Hub4

Hope one of you good people can help me with any suggested solutions to a problem I have had since Monday.

I am on Bt Infinity 2 on copper fibre from exchange box about 400m away but for last couple of months, speed has been between 29 - 34 mbps. On Monday, ran the speed connection tool. Picked up a couple of issues with line which were fixed. Asked to make additional checks but as our socket was not listed (mk2), had to ring in for assistance.

Got pushed round a few numbers until someone overseas did some diagnostics and moved me to 5ghz. Was told speed would improve (it did and now 45 mbps) but range may reduce for Wi-fi. Not only has it reduced but it is awful now. Literally will only work within 5 steps of hub.

Spoke several times to BT but they say they cannot help further. They only guarantee speed to home. Said I must have a new device interfering or some other changes in house. No new devices in house for 6 months and was working perfectly throughout house until doing the test on Monday. BT not having it though. It has actually worked perfectly for 4 years.

can anyone suggest to me anything I can try on hub. I notice the IP address moves from when I am on top of hub to kitchen 8 steps away or go upstairs. Full signal but no internet available. Have reset hub to factory settings, renewed lease on all devices, still no change. Can you make ip addresses static?

Just too much of a coincidence that something must have changed when BT were checking my line but they are adamant nothing done and cannot help. Really unimpressed.

Any help appreciated. Thanks

Try separating and renaming the SSIDs.

Are Ethernet connected devices running at full speed?

If they are not. Is there any noise on your phone calls? Dial 17070 and select option 2, there should be no noise between the announcements.

Hi Keith.

Many thanks for responding.

i have tried the split and the quiet test. No difference and no noise heard.

What do you mean exactly when you ask if Ethernet running at full speed?

Really makes no sense to me to claim no issue with them when I can honestly say no problems in four years until after tests and settings check remotely.

Re: Wi-fi dropping and range radically reduced - Hub4

You need to go back into the Hub and change the name of the 2.4ghz and 5ghz wifi SSID (the names you seen when you connect with a mobile device) try this link

http://bt.custhelp.com/app/answers/detail/a_id/44798/~/i-have-problems-connecting-5ghz-and-dual-band...

Then you can choose between  either 2.4 (slower but wider range) and 5ghz (faster but smaller range) see which works best.

As to ethernet, I think he was asking if you have any devices plugged directly into the hub and if they are working at full speed

Re: Wi-fi dropping and range radically reduced - Hub4

if you are on FTTC and using HH4 then you must also have a separate modem conencted to the openreach wall socket.  from your post the internet conenction to your modem is ok and more than likely ok to hh4 so problems as others have said is your wireless conenction

splitting the wireless networks and just rename the 5ghz network by say adding a 5 to SSID to distinguish from 2.4ghz  you can then log into either or both networks delpending on device capabilities.  I would also select channel manually rather than leave on auto

Re: Wi-fi dropping and range radically reduced - Hub4

Many thanks injolly and Gary. Unfortunately this has made no difference.

i am wondering now however if I need to make a change under 2.4ghz setting. Let me explain that when BT ‘helped me’ on Mon and changed the router settings, this is what I think they told me to do but only thing is I did not rename SSID so it overwrote I assume what were the original settings. The Wi-fi has been terrible ever since.

so currently I have the 2 SSID s, one with 5ghz and not synching with 2.4 ghz. Both are same poor Wi-fi range now.

wondering now do I need to do anything on the 2.4 ghz setting? 

This is set to 802.11 b/g/n up to 144mbs. Automatic channel selection. WPA2 only. Wireless network enable set to yes.

try selecting the channel manually - turn off auto select - for both 2.4/5ghz networks

Moved 2.4 SSID from auto channel 6 to 3 and 5ghz SSID from auto 48 to 40. Still no difference sadly.

R e: Wi-fi dropping and range radically reduced - Hub4

You can download apps for android phones that let you see how crowded the spectrum is.

the funny thing with wifi is the channels, while having channels numbered 1 to 13, there are actually only really three, 1,6 & 11 as they overlap. If neighbours are using odd channels then they can conflict (it's worse than sharing the same channel)

or you have a source of noise.

 

assuming, the wifi is the bottleneck rather than the router/wan

Channels 2, 7, and 12 do not overlap, also 3, 8, and 13. The problem is also that some routers use two split channels to get 40Mb bandwith.

In many built up areas, the defualt channels of 1,6, and 11 are fully occupied with strong signals, so using intermediate channels like 3, 4, 8, 9 and 13 is the only option to get reasonable throughput, despite crosstalk from the default channels.
