DG834V3 oddity

Every two or three days, it has started disabling use of its wireless
access point. Enable Wireless Access Point is ticked, Allow Broadcast
of Name (SSID) is ticked - every few days I have to change the status
(tick/untick) of Wireless Isolation, then access returns.

At the moment it is connecting with Wireless Isolation ticked.

Is this a known problem?

Are you sure the problem is really at the Netgear? Are you seeing the
disappearance of the AP from more than one computer?

Although I don't see any connection to your problem, why are you using
Wireless Isolation anyway? That just breaks the ability of devices
connected via wireless from networking with other hosts on the LAN. It may
be a very nice feature when say you are running a hotspot for a coffee
shop, but I don't see it as helpful in any home networks.

But should the feature not work flawlessly if provided by the device?

Why the word "but"? Again I say that I see no connection between a use of
Wireless Isolation and Harry's reported problem.

Only one PC normally uses it wirelessly, but when that one looses
access I have fired up another and it also could not connect. The
access point remained visible throughout.

On logging in to the Netgear using a wired PC and changing the status
of the Wireless Isolation, they were able to connect again.

I guess it was one of those occasions when I just wasn't paying much
attention to what I was doing, ticked the box then subsequently
ticked/unticked the same box without looking simply because it had
fixed it the previous time.

Assuming the signal strengths are good and there is no wireless
interference, in that situation I would next try degrading the encryption
to WEP which I find has fewer brand-to-brand issues.

I see no connection - that isolation feature lies within the routing rules
that allow or disallow LAN/LAN communications and it has nothing to do with
the router's wireless, its configuration or its transmissions.

No I, but the connection starts to work again - curious.

The only other thing, apart from changing the status of that setting,
which I'm doing is clicking the 'apply' button.

A *VERY BAD IDEA* to change from WPA2 down to WEP. All
you will do is invite anyone local with the correct wireless card with
packet injection used on LINUX to obtain your password within 15mins.
There are no brand-to-brand issues, that is a poor excuse to get people
to lower security and allow their network to be broken in to and used.

That doesn't alter the connection from either PC unless you are connecting
via some strange route through the other computer and back out to the router
again!

It sometimes happens when a neighbour sees your router and just
tries his luck. By trying to connect, the router gets two different
requests and acknowledgments, so disconnects everything. Once
your neighbour has stopped messing about, your connection will be OK.

On the DG834G v3, all you need to do is select WPA2, set the channel
to something like 13 and manual selection to stay out of the way. This will
stop the router switching from channel to channel each time it hears a
close network. That can also cause disconnections when it changes channel.
Leave it to other networks to shift!

Show your SSID, hiding it will be of no benefit as people can see it
anyway using NetStumbler.

If your PC keeps disconnecting, it is your PC at fault. You might also
check whether you have restricted the times you allow the Internet to
be accessed. Can't remember which part of the setup page that is in now.

Check you are using the Windows Wireless connection software, it works
much better than programs bundled with network adaptors etc.

What you describe is not a known problem with the DG834v3. You can
always upgrade to the latest firmware. I would suggest *NOT* using DGTeam
firmware for the DG834 as it might have lots of features but doesn't work
correctly. The data throughput is far far slower than with DGTeam than the
official netgear firmware. The DGteam stuff has played with settings to
alter
noise figures which act as a real disadvantage and make the connection
unreliable for some with slower ADSL speeds.

Could it be the router's firewall interpreting some form of wireless
access as an intrusion or DOS attack and disabling the AP?

Tried looking at the routing rules/firewall setup? Looked at the logs?

I've used the v1, v2, v4 (which, with the Broadcom chipset is my favourite
along with the GT) and v5 but I never used a v3.

There was a nasty hardware design problem in the v2 whereby a strongish
wireless signal at the AP would cause the router's wireless to simply shut
down. And that fault could be caused by another nearby router or an AP or
even a DECT phone base station. I don't know if that fault had already
been fixed in the v3, but you might see if any other such wireless
transmitting devices are within say 6 feet of your router.
