Constant disconnects from wifi

Hi all,

our family switched to Infinity this week. We have 3 laptops and 1 desktop pc in the house, all using wireless connection and we all get frequent random disconnects. They last around 2-3 seconds and then reconnect back. The lights on BT Home Hub 3 are all steady blue and signal on each wi-fi is full, so its definitely not distance or obstacles issue. I checked the browser Home Hub settings and can see there the disconnects as 'Client disassociated, Reason Code 4 or 8'. I have no idea what does that mean and what to do. If anyone can make sense out of this log, i'd be more than happy.

 

Regards

Andy

Re: Constant disconnects from wifi

Hi and welcome,

 

Have you tried changing the wireless channel the HH3 transmits? 

 

Go to wireless in Advanced settings http://bthomehub.home/ and change the channel from Automatic to a set channel number.

 

A good and free scanner to identify a clear (or least used) channel is http://www.metageek.net/inssider_download/

 

It does look that some people have become dissatisfied with the HH3 wireless performance and decided to replace it with another manufacturers..... http://community.bt.com/t5/BT-Infinity/List-of-Routers-to-replace-Home-Hub-3/td-p/298203

 

Look out for other things that may be interfering http://www.pcpro.co.uk/features/367672/whats-killing-your-wi-fi

Re: Constant disconnects from wifi

Hi,

 

I've been investigating this same issue on my Home Hub 3 since it was installed around 6 weeks ago.

 

At first it was a daily occurance, so I scanned and then altered the WiFi channel to the best available. This did not help.

 

I noticed in the logs that the lease for all attached device had expired and that they were all requesting new leases, i was on the default 1 day lease for each device.

 

I changed this to 21 days and the issue was resolved, now though I have passed day 21 since the Home Hub 3 was last reset and the problem has returned. As a result I am now convinced that the the cause is that the lease for the wireless device has expired and that they keep renewing but not reseting the lease time correctly in the firmware.

 

If you go to Advance Setting, Home Networking, DCHP Table screen and keep refreshing the information, you will see them keep changing to expired and counter reseting.

 

i.e.

Note that my lease time is still set to 21 days, thus the issue will be activated every 21 days, or 30240 minutes.

 

Does anyone know if there are any firmware updates?

1. Product name:BT Home Hub
2. Serial number:+058720+1221010116
3. Firmware version:Software version 4.7.5.1.83.8.57.1.3 (Type A) Last updated Unknown
4. Board version:BT Home Hub 3.0A
5. WAN:PPP Connected

 

If not hopefully BT are viewing this and will fix the issue.

 

Cheers

Kev

Re: Constant disconnects from wifi

The renewing of DHCP leases is a known problem and has been reported many times before.

One solution is to forget DHCP and use static IP adresses on your network.

Re: Constant disconnects from wifi

Now there is a thought, use a different DHCP server.

 

Feels a bit weired though, buy a new HUB and use the 5 year old one for the DHCP server.

 

I sit here questioning if anything about my upgrade from BT is good (Infinity - with it laggy performance, BT Vision - with it bugs, BT Home Hub 3 - with its faulty DHCP).

 

If i sat at work and released such poor upgrades into production i'd expect to be out of work very soon.

Re: Constant disconnects from wifi

I use static IP's on my Home Hub 3, all outside the DHCP range and I've had no issues, so I think this would be worth a try.

Also, what version hub do you have? Mine is a B which might be helping me as I know version A has "issues"

Re: Constant disconnects from wifi

Static IP's are the simple answer to the problem I use a version 3A myself and it stopped all problems

Re: Constant disconnects from wifi

Hmmm. DHCP is quite a fundamental function of a router.
If they can't get that right what hope is there that more advanced functions will work?
That said though I haven't noticed it being a problem for me (using HH3b)

Re: Constant disconnects from wifi

Agreed, DHCP is the basics and should be perfect.

 

How long have you have yore 3B version?

 

I dont really want to go Static and have no DHCP server at all.

 

I guess I could do half & half, have regular connections static and guests on DHCP for 21 days.

Re: Constant disconnects from wifi

I've always used static IP's outside the DHCP range for regular connections. On my last router (a netgear) I deliberately set the DHCP range to start at 192.168.1.50 and then when other people connected to my network it would be on auto at the DHCP worked fine.
