routing problem?

Hello,

After some hesitation today I bought a wireless router/modem. I used to have
an Alcatel Speedtouch 510v4 but I wanted wireless network for my laptop.
Therefore I bought the Zyxel Prestige 660HW and a PCMCIA card: Zyxel ZyAir
G160. After reading the manuals I swiftly installled the hardware and made
the necessary configuration settings. This resulted in a lot of good things:

- My modem makes connection with my isp.
- All my aattached to the modem [the big ones -> wired, the laptop ->
wireless] do perfectly make connection to the internet
- All my PCs wired to the modem can see each other via the Lan

However:

- My laptop can NOT see my other PCs in my lan: I CAN ping to my
modem/router, but I CANNOT ping to the PCs wired to the modem/router.

Hmmm,... this looks like a routing problem...

As far as I can see all the network settings are fine: they are in range and
the masks are 255.255.255.0 and the gateway is set to the modem 10.0.0.138
on all PCs...

I must admit I don''t run a DHCP server, so all network settings are made
by hand. The IP addresses I use are:

pc1: 10.0.0.150
pc2: 10.0.0.151
pc3: 10.0.0.152
laptop 10.0.0.160
modem 10.0.0.138

Perhaps can anyone share some light on my problems?

any help would be greatly appreciated.

Thanks in advance,

Hans

Q

Hello,

Thank you for your response.
I read the document but unfortunately no cigar.

The problem is that the network settings on all pcs appear tp be correct:

- the laptop has wireless network connection to the modem/router and the
internet
- the laptop can ping computers on the internet
- the laptop can ping the modem/router
- all big pcs [windows and linux based] have wired access to the
modem/router and the internet
- all big pcs [windows and linux based] can ping each other
- all big pcs can ping the modem/router

but

- all big pcs [windows and linux based] CANNOT ping the laptop
- the laptop CANNOT ping the the big PCs in my network

So you can see that the network connection should be right, but probably
something goes wrong with the routing
It looks like if the modem/router doesn''t want to mix LAN/WLAN.

Anyone any ideas?

Thanks again,

Hans

Maybe just pings are blocked on that machine?

Hello,

Thanks for your response.
But alas. If I make a wired connection to the laptop all PCs including
laptop can ping each other, so no problems there.
If I remove the wire from the laptop and use the wireless network adapter I
can't ping to the other PCs and vice versa.
I can ping the network/modem router though and I can connect to the
internet...

It looks like that my wlan and lan don't like each other...

Any ideas anyone?

Thanks again and regards,

Hans

Eureka!

Finally after hours of trying and searching on the internet I found a
description about a similar problem with a prestige 650.

The solution is to go via telnet to the router [not the web interface!].
Go to general setup and make sure the bridge option is marked YES.

It now works like a dream...

Thank you all!

Cheers,

Happy Hans

FWIW, I've got a Zyxel Prestige 660HW as well, no problems in a mixed
wired/WLAN network.

Tell us more about the OS on that laptop; and, why not, try a
different IP address in the range between .138 and .150 instead of
your laptop's .160

Hi Andre,

Thank you for your support. As you probably have seen, I managed to solve
the problem in the end. I could not find the bridge-setting in the web
interface though...

my humble opinion is that all functionality available in the telnet
interface should be available in the web interface as well...

Thanks again and regards,

Hans
