[Modem] VPI/VCI 0/35 working should it be 8/35?

I just bought a locally used ATT 2wire modem/wireless router. I reset and everything works and connects fine. I noticed that the VPI setting is 0 and VCI 35 From what I have read (and from my old modem I think) the VPI/VCI should be 8/35. I could just try it changed but if it's working I don't want to mess it up. Would it be better to change? Thanks

Is it possible that it doesn't matter what it is set to if it autodetects the correct setting?

The 2wire uses a pvc search list and 8/35 is on the list.
You will not mess it up by changing it to 8/35

Can you post the software version of the 2wire and the first four digits of the serial number?

Thanks, I changed it and everything still works fine.
Software: 5.29.109.5
Serial: 2807

Also, it defaults to Bridged LLC. Is that better than Bridged VC-Mux? Or Routed?

I appreciate the help.

If you change the encapsulation from LLC to VC-Mux, it will likely stop working.

Routed could mean more than one thing, but if it there to set up RFC1483 routed service, that will not work.

I think bellsouth uses vc-mux with PPPoA, someone else will need to confirm or deny that info or you could check it out yourself.

I think the software version is a bellsouth version.
Its odd that a bellsouth version has the wrong vpi/vci
The serial number... first two digits are the week the next pair is the year of manufacture.

Did you notice if the 2wire had a default username and password when you did the factory reset?

Don't know about vc-mux but the SE frowns upon PPPoA now and by default uses PPPoE though PPPoA might still work in some areas.

After a couple of times clicking I need help with my password I was prompted to look for a 10 digit number under the serial no. It took that as the password. The LLC works but which is better Bridged LLC or Router LLC

Looks like I'm wrong about the software version the bellsouth versions started with 5.29.109.11
That explains the vpi/vci

It's not about which is better, it's about what works and what doesn't.

That's the Default WEP key for wireless.

The isp controls which ATM Encapsulation method they use.
My isp uses Bridged LLC if I switch to a different method I won't get a connection.

yea...it's like asking if 999 or 911 is better.

I was thinking it was like setting my old modem to bridge mode. Guess not.

Here's a link for putting the 2wire in bridge mode
Bridge Mode for the 2Wire 2701HG-B

PPPoA still working for me in Georgia. I do understand from posts here and elsewhere that it may eventually stop working. I use PPPoA because with it you can use the default 1500 MTU without worries about changing it everywhere to the 1492 required for PPPoE.

Do you know the type of encapsulation used with the PPPoA

My AT&T setup is using the 2Wire 2701HG-S and is defaulted by AT&T to PPOE bridged at 0/35. AT&T setup put this in initially. Marietta/Atlanta area...

You should have a look at the detailed log there are messages in the log which show the vpi/vci that is being used below is a example

found BRDG_LLC PPPoE on 8/35
preferred pvc 0/35 not found. Using 8/35

The "preferred pvc" is what is in the ATM circuit identifier" boxes on the config page
