Sky netgear router overheating and causing speed problems

Hi guys.

Not sure if anyone can help but was at relations yesterday and he said
their Sky BB goes very slow after about 30minutes!
Can be cured by re-setting router/switching off/on.
Of course Sky helpdesk very unhelpfull - suggesting problem is long
(10m) RJ11 from a filtered faceplate to modem - unlikely to be problem
on end of longish phoneline from exchange! Loss is quite high at 46dB.
Went into setup and syncing at about 4780 - even when slow browsing at
about 22k (on a speedtest). Normally measures about the 4700 on a speedtest
Seems like using windows network 'repair' setting also makes it good so
I suspect it is a LAN/router problem.
Same on 2 PCs connected so any words from Sky to re-install etc are cr*p.

I did notice that the router is VERY hot and even making the table it is
on hot.
I have advised him to put in the stand to keep cool and report back.

Has anyone else had similar experiences?

Mike

Yes. Standing the router upright in its stand makes a massive
difference, as does disabling UPnP.

The guy did that sometime Sunday evening and e-mailed me back last night
to say only one 'slowing down' in that time.
So overheating does seem to be the main problem.
The idea of putting the Modem in the fridge (would need very long cables
to kitchen) or getting a mini-beer cooler for the office has just
occurred to me!

Seriousely you would have condensation problems if you tried anything
like that. Stand Router on edge (lets face it that is what the feet
are for) & if you still have problems take it off the bleeding
windowsill & place on floor, under desk & you shouldn't have many
problems

I was only joking about the fridge Kraftee!! tho the beer fridge in the
office might be welcomed

yeh agree about the feet but one can see why people do otherwise as the
top has nice shiny surface etc etc and the bottom is all labels.
Also, with 3 CAT5s connected, it is more stable flat down. It is already
away from the window!

Incidentally are the new GPO 'filtered ring wire' NTEs appearing yet?
Presumably the third wire has a proper low pass filter in it to allow
the 17c/s and kill anything at BB frequencies. As opposed to normal NTEs
which just have the 1.8microfarad capacitors.

I guess you have come up against people who disconnect the ring wire
then use cheap (without the capacitor) as opposed to 'proper BT
approved' filters and so the phones don't ring.

Reading a post recently elsewhere, do some of the DECT phones just use
2wire (like US phones) without the ring wire needed?

My 'Phone Socket wiring system handbook' from about 20years ago is
brilliant at how to wire 8700 and Ambassador phones and even where to
put the 330ohms to convert low impedance bells to high impedance.
Ah the good old days of dial phones and anti-tinkle thermistors.

You can't be to sure as you would know if you spend as much time on
here as I do (isn't it amazing how that quick 10 minutes turns into a
few hours, well at least she who must be obeyed, yeah right, knows
where I am)

Here again it wouldn't have been the first time I've seen one on a
window sill but I must agree about the bad design. The old 'blue box'
design do seem to have better heat dissapation the the white plastic
icky things> I ordered a Netgear switch, can't remember the name but
it was definitely the version 1, so they sent a plastic v2 model
saying that the v1 wasn't available. The joke is...I believed them to
my cost so that's yet another piece of plastic technology under my
desk.

Certainly I'm fitting them in as many places as I can, leads to a bit
of waste though as we can't get the faceplates on their own now, so
you have to use the faceplate of a new NTE5A front & throw the rest
away.....It's called progress you know...

Actually it didn't make much difference to the phones as most
reasonable to good filters contain a bell capacitor anyway & what with
most phones using tone dialling .....no bell tinkle

It's becoming more & more prevalent with more & more of the new
models. Can't help but wonder if we'll start to see the same types of
problems as when they've used multiple master sockets, faint/one way
transmision & the like..

They certainly don't make (or maintain) them like they used to. The
good old days when you really knew someone was ringing the circuit you
were working on. It's taken nearly 17 years to get the worst of the
'MDF rash' of the back of my hands you know, that's when men were men
& the others wore hand protectors ;-)

My sky router lasted exactly an hour before overheating, even stood on
the feet supplied. Sky sent a replacement (took them 2 weeks to
respond to email, then a further week to send out replacement).
Replacement lasted less than an hour.
I opened up the case and could see the effect of the heat on the chip
and circuit board, got an old heat sink from a PC CPU, cut it down to
size and superglued it onto the router chip - problem solved.
I would have thought by now that netgear and other manufacturers could
have come up with a chip with a fan on or at the very least, a heat
sink on. Most motherboard manufacturers put heat sinks or fans on
their onboard graphics chips because of the same problem, so I can't
see what is so difficult about this problem that it takes them so long
to come up with a fix for it.........
