Netgear DG834G router problem

I'm running a small home network based around the Netgear DG834G
wireless router. A PC and a Mac are connected via Ethernet and a PC
laptop and a Mac laptop are connected via wireless. The firmware is
V.2.10.22

Right now the wireless doesn't work and I've no idea why, what caused it
to stop working or what procedures I might use to test it. This problem
is reoccurring and intermittent. I can find no pattern in the router's
behaviour. Sometimes the wireless works and sometimes it doesn't. And
I've no idea why. Neither the PC laptop, using a Prism 802.11g card, nor
the Mac, using Airport, can detect any wireless signal. It was fine two
days ago and, as far as I know, nothing has changed. This has happen a
few times before - it stops working, it starts working.

Anybody any idea what might be causing this and what I might do to
rectify the situation?

Many thanks.

Try changing its wireless operating channel.

You asked this in uk.comp.home-networking, and I give you the same answer:

This can happen when another wireless device is too close to the router.
It could be a wireless client (the Prism or the Airport) or another access
point or even a cordless phone base station. Try removing any other
wireless device to more than 5 metres from the router and see whether that
allows it to recover.

It's a fair cop guv! Apologies for the cross posting.

I've managed to move the router about half a metre further away from a
cordless phone base station but I need to get a long Ethernet cable to
move it a long way away. It was about 1 metre away from this base
station now it's about 1.5 metres. This move hasn't made any difference.

How does a cordless phone base station interfere with a wireless router?
I understand that they're both wireless devices but what symptoms of
interference would I notice? The symptoms I've got? ie the wireless
network working and not working seemingly at random?

Thanks for your reply.

Cross-posting would be fine; you are multi-posting which is not.

I've no idea how it works but on many occasions in several different
locations I have experienced this exact problem with the DG834G, both v1
and v2 and regardless of software version, where the local presence of
strong radio signals of various kinds will cause the router's wireless
access point to shut down intermittently.

I have 7 of these devices installed in five locations on two continents.
In one location I was not able to separate the router sufficiently and
there I had to switch off the DG834G's wireless and I just got a plain
Motorola WR850G AP to plug into one of its LAN port. The DG834G has a
wonderful package of features - just pity about the flakey AP wireless.

I've had the same problem.

Strangely it seems to be really unstable when first used when I switch my PC
on.
But when you reconnect a couple of times, it seems to settle down and is
problem free for hours.

My DECT phones base stations are some distance away so that theory doesn't
seem to hold true for me.
I suppose it could be the neighbours.

My next port of call is to change the channels.

But it can be stable for ages with no apparent problems.

What's the difference between cross-posting and multi-posting?

According to this article,

http://www.islandnet.com/~tmc/html/a...#Cross-Posting

cross posting is permitted if one is unsure which newsgroup to post to.

Just curious.

Still haven't fixed the router.

cross-post is one message posted to many groups. One reply from any
one group would go to all groups usually.

multi-posting is several separate messages (could be the same messagE)
posted to different groups.

I have 2x DECT, 1 two foot away and the other about ten feet. I use the
laptop anywhere between 15 - 60 feet from the AP, through 2x
floor/ceilings and usually manage 54Mb most of the time. Only
occaisionally do I have problems, but the fix to get it back on again
is to simply change the operating channel - even changing it, then
changing it back to the original channel seems to work.
