Hello folks.

Not strictly a VFX/XNET question, but this seems to be where those who might know hang out.

I have a Linksys WRP400 connected to a Dynalink RTA1320 in half-bridge mode.
I have the RTA1320's local IP address set to 192.168.0.1, the WRP400's local IP address set to 192.168.1.1 and routes on the lan with 192.168.1.1 as the gateway.
The WRP400 correctly gets my internet IP assigned to it and every thing works nicely. I get internet and I can connect to both devices from within the lan.

However... when the RTA1320 really* loses it's ADSL connection the WRP400's local IP address reverts to it's factory default of 192.168.15.1. Obviously this means no more access from the lan, I have to get a 192.168.15.* address onto a machine and reconfigure the WRP400.

* I say 'really' because simply clicking on the 'Disconnect' ADSL button in the RTA1320 doesn't cause it, but power-cycling it or changing ADSL settings (eg (en|dis)abling ADSL2+ support, or trellis, or whatever) is enough. Perhaps it is triggered by the RTA1320 being to slow to supply the internet IP to the WRP400... or sumthin'.

My WRP400 has firmware version 1.00.04.c, which Linksys support tells me is the latest version. However they suggest I reflash with that same version. They've directed me to wrp400_1.00.04_us.tgz to use, it does have files with May 23rd modification dates so might be a more recent one.

Their support person didn't instil great confidence in me, so...
has anyone experienced this before?
will the US firmware work alright here?
anyone know what actual file in the .tgz I would use? It looks to be the full source distribution.
any other advice?

Cheers.

Once you set the local LAN subnet it should not change no matter what, unless the unit was factory resetting itself which would mean it's faulty in some way, Configs supplied by use don't touch local LAN settings and if we were it would happen approx every 48 Hours.

Does it occur when you repower the WRP400 ?

Also what if you made your LAN 192.168.15.x this si a work around but would be interested to see if it still occurs using this Subnet as your LAN setup.

You probaly won't be able to do the firmware upgarde as it will require a password as it could effect the Voice, and if you did the Voice config would resend the firmware that is supported on the network.

Yes I am a employee of WxC (My Profile) ... but I do have my own opinions as well

Sorry, I wasn't completely clear. I'm not signed up with xnet, though that is the plan and why I bought this little chap. So it's not due to you updating the firmware... at least I hope it isn't! ;)

This forum seems to be about the only place that WRP400-knowlegdgeable people are posting.

maverick: Does it occur when you repower the WRP400 ?

No, repowering is fine. All settings are successfully retained when doing a repower. All settings, except the Local IP Address, are retained when the modem connects the ADSL. That's why I suspect there is a problem with the WRP400 falling back to factory default external IP and Local IP when it's DHCP request for the external IP is not answered quickly enough by the modem.

maverick: Also what if you made your LAN 192.168.15.x this si a work around but would be interested to see if it still occurs using this Subnet as your LAN setup.

Yeah, I guess that'd solve my problem. I've been avoiding it on principle, and the hassle of changing all the various setup. I don't think I would be able to detect whether the problem is still occurring, I suspect it would but it just wouldn't be a problem for my routing.

maverick: You probaly won't be able to do the firmware upgarde as it will require a password as it could effect the Voice, and if you did the Voice config would resend the firmware that is supported on the network.

I've got the administration passwords, so I can. At least, I could if I was confident the '_us' labeled firmware was correct... and I knew what file was actually the firmware. The .tgz Linksys support told me to download looks like it's just a whole lot of different source distributions.

Presumably some VFX customers have their WRP400 half-bridged to a modem, and presumably some of them have changed the Local IP address. Anybody else every come across this problem?

Does VFX use a custom firmware, or just the standard firmware and custom configurations?

Thanks for the help.
