Re: [PLUG] New Comcast wireless modem with old Buffalo wireless router

[gary@duzan.org]

   The FiOS folks did something similarly antisocial to me. I've been
running for years with the same router that they gave me when I signed
up, but then they decided they didn't want to support that router model
any more, so they gave me two choices: 1) pay them a ludicrous price
for a refurbished router, or 2) pay them a monthly "maintenance fee" to
keep the current router. Amazingly enough, my email asking what that
fee buys me went unanswered. Naturally, there is no way I could get a
"supported" router from a third party provider. I'd be tempted to try
to start up an ISP utilizing wireless mesh and a fiber backbone, but I
know there would be far too many obstacles.
