Greetings: My adsl 'library' is sketchy but did come up with the following: http://roaringpenguin.luky.org/pppoe/how-to-connect.txt and--files: DSL-HOWTO and DSL-HOWTO.pdf.. Dunno where I got them..

Good luck with Verizon; wear a hat so you don't pull out much hair... <grin> If all above are pppoe, I suspect they should work OK.. If Verizon, Ohio, same as WV; I have used a Westell Wirespeed; and Westell 6100, modem only, with my Verizon pppoe setup.. I've also used an Actiontec GT704WG combination wireless/wire router modem.. The two former ones were no problem using rp-pppoe, Slackware 10.1 and 10.2 with the 2.4.XX kernels, once I got my username and password assigned, that took a long time, because Vz said Linux wasn't supported... One caveat with the Actiontec is that I had to use the 192.168.x.x group of private addresses for the wireless and wire ports.. It didn't like my usual 10.x.x.x assignments.. The first two modems didn't care of course, being "dumb" modems.. I had to borrow an XP machine to use their setup disk but once getting the proper username and password installed; went to Linux for operating plus my normal mail and browser setups, but that's another story.. The Vz web mail is full of ads and some other restrictions I'm not used to, or don't like... <grin> I've retained my older ISP's mail boxes that caused a little problem with SMTP relaying because Vz didn't like that.. Have that figured out now.. I connect to the INet ADSL, 'getmail' from kvinet.com and browse the Web with either FireFox or Opera.. My MTA is Sendmail, relaying via outgoing.verizon.net which means I had to enable the smtp auth lashup.. All is now well and awesome.. :^).. Played around with one wireless card on another machine, just for fun, but the Actiontec has 4 wire/RJ45 ports that is all I need for now.. Again, wireless, the caveat (can I change this?) is that the LAN must be the 192.168.x.x addresses.. I think M$ uses them, so there you go... ???? > http://kb.efficient.com/display/1n/index.asp?c=&cpc=&cid=&r=0.4739191 I will look at that site.. > Lastly, I've been wondering if two DSL modems can be > connected back-to-back. Any links about this would be nice. > > aDSLmodem <RJ11crossoverRJ11> aDSLmodem > > Ethernet|ATM<>ATM|Ethernet Well, lemma see.. Normal Telco POT red and green pair are, when enabled, a serial loop.. In olden times the CO battery, on hook, to the subscriber was nominally negative 48 volts on the red measured to the green.. Lately, I notice they don't observe that "rule" anymore noting that they hooked me up in the reverse and it works OK, except for one very old speaker phone that needs a special RJ11 cable to power it's electronics.. Also, our drop line is no longer red and green, but blue and white/blue... Go figure.. How the ADSL is configured on top of this--I would like to know too.. I do know we're muxed in this complex with only 150 subscribers going to a switch that routes to the CO with fibre.. Our "frequencies" are, obviously, above the standard voice band cutting off around 3kHz-- as the Vz supplied "DSL filters" will confirm, that go on each POT device.. A long winded way to say that I don't think a RJ11 reversal or crossover would work.. BUT--I sure have been wrong before. <grin> HTH, as you have bailed me out countless times in the past.. One last thing: The Actiontec modem/router will work fine allowing a LAN like normal hub with up to 4X wire/ethernet connections plus many wireless connections; as long as--here anyway--all use the 192.168.x.x assignment setup.. The modem/router itself is 192.168.1.1 for configuring, etc and the other devices should be 192.168.1.=>64... (In WV; Vz supplys the Actiontec for $30.00, payable in 3 installments on the phone bill.)
