I regularly stream audio (Spotify) over Bluetooth from either my
phone or a tablet to a Bluetooth receiver connected to my old but
Every session without fail, doing this makes my wifi router reboot
more than once. I know as my phone will drop onto 3g whilst the
Router is a Thomson tg 785 from Plusnet several years ago.
Any thoughts /pointers gratefully received

Which implies that the data stream from spotify is reaching your
phone/tablet over WiFi from the router that crashes?
Any firmware updates available? It's not unknown for "domestic"
routers to crash when asked to maintain a reasonable data stream from
a single source. Mind you spotify is only audio so shouldn't be
particulary taxing compared to video...
Bluetooth and 2.4g wifi use the same frequencies so do interfere.
However that shouldn't cause a crash.
Does the router crash if you stream the same thing using a wired connection?
Have you checked for a firmware update?
It maybe easier to buy a new router than to diagnose it.
All the wifi of routers everywhere share just 16 frequency bands. By
default, all sending gear and receiving gear is defaulted to band 7. If
you change the band, you must do on all your other devices in & out.
However, you will be more or less garaunteed a full band to your self as
no one else ever changes from the default.
Using the default of 7 means that all neighbours are also clashing
signals that your net has to abandon and ask for a repeat send. You get
lets of dropped packages.
If your Wifi is under such stress already, the bluetooth may be the
Otherwise, I have nothing else to offer.
14 channels at 2.4GHz, of which 13 are legal in the UK and one of those
tends to have patchy support.
Not IME, channels 1,6,11 are the common bands as they don't overlap.
Not so, if you change the channel on the access point/router, all
connected clients will quickly follow it to the new channel, without any
Many routers automatically and continuously select the "best" frequency.
Bluetooth uses spread spectrum frequency hopping on a larger number of
narrower channels, an attempt to avoid interference from other devices
(e.g. WiFi) sharing the 2.4GHz band.
Wouldn't surprise me to find interference between bluetooth and wifi
devices in a particular situation, does surprise me it crashes the
router so repeatably.
Plusnet do have some Thomson firmware on their community website, if
that didn't help I'd buy or scrounge a router from someone.

*Personally* I like to first have a listen and see what else is out
there and at what signal strength (WiFi Analyzer app on my phone )
and then position the gear I'm working on somewhere 'quiet'.

 I have also a WiSpy dongle (WiFi spectrum analyzer) and that was
good for finding rouge kit that was broadcasting all over the WiFi
spectrum. One was a cheap TV sender thing and the other the rear
speakers on a surround sound system (that had stopped functioning and
gone bad (or the other way round)).
When I only had 2.4GHz I used to do that, and preferred CH13 when that
was an option.
Now I have a dual band router choice of channel barely seems to matter
(due to fewer competing 5GHz signals with shorter range and worse
penetration of walls).
