Can't get access to network

Hi there,

I have a very puzzling problem and was hoping that some kind person out
there may be able to help me out:-)

I have a D-Link DWL-G710 AirPlus Wireless range extender which is connected
to a network (with a domain server running NT4.0), and although my laptop
can connect to the range extender fine (with excellent signal strength),
it's not giving me access to the network. If I go to the place which would
normally show all the computers connected to the network, very few appear.
If i refresh the box from time to time over the space of a few minutes, then
one or two more may appear but it would still be well short of the full
list. Then if i try and access one of the machines in the list it thinks
about it for a while and then tells me that the machine is not accesible.
This happens regardless of which machine I try and access. At first I was
thinking that it may have had something to do with my pc's TCP/IP settings
but:

I also have a Belkin F5D 7130 Access point/range extender attached to the
network too elsewhere in the building. Now I can connect to this one fine
as well (with decreased signal strength cos further away) BUT the difference
is - this gives me full access to the network!

The thing is I would rather use the d-link one because it is in my office
and gives me full signal strength. I've tried changing the channel on the
D-link but without success.


If anyone has any thoughts at all on what the problem is then i'd be verey
grateful for your help.

Thanks for reading

David

My thoughts are that you need to do ipconfig/all on the machines, and see
what IPs are being allocated. It may be that the D-link handles things
differently here.

AD domains rely on a special type of DNS if the computer is not in the same
subnet as the server. If this isn't working then you might be able to see
machines in the same subnet but not outside of it.

Also bear in mind that netbios resolution takes ~15mins anyway. Are you
waiting long enough?

Hi Ian,

Thanks for your reply.

Basically everything on our network (workstations, servers, printers &
wireless kit has a fixed IP address within the range of 192.1.1.1 to
192.1.1.254. and the subnet for all machines is 255.255.255.0 What I was
wondering was whether the Belkin and the Dlink are clashing in some way
which is what is causing the problem. I'm not at work again now till monday
but I was wondering whether it would be worth powering down the belkin,
connecting to the dlink in my office and see what happens.

Thanks

David.

Hi again Ian,

One thing you mentioned in your reply about netbios resolution - thanks for
suggesting this. I take your point, but with the Belkin, conection to the
network is instant so i'm not sure that waiting longer would make a
difference. I'm thinking that the answer lies somewhere in the D-link's
settings - either that or a clash with the Belkin. My problem is that my
networking experience is ony limited so I guess i'm just 'getting by'.

Thanks again

David.

You should bear in mind that the signal strength reported in the system tray
is
actually the strength of 2.4GHz or 5GHz signals within receiving distance of
the wireless card. This
reading does not take into account Signal-to-Noise ratio (SNR) and is not to
be taken as an indicator of wireless signal strength. A microwave magnetron
would cause this signal strength to show as excellent although the signal
would be mainly noise and the wireless signal itself would be very poor as a
result, for example.

If you run Netstumbler you will be able to see what the SNR is and will have
more
information to hand for troubleshooting:
