You can try AT+MS=V90. Sometimes a v.92 client modem can confuse a v.90 host with the client's attempt to connect v.92, resulting in a v.34 connect. The above init forces the client to start negotiations at v.90 instead of v.92.

"They are V90 capable and also offer DSL which is not currently available this far out from their system. Is there an init string or something I can do to speed things up? "

 

The distance limitation on DSL is also a good reason your dialup is not connecting at V90 speeds.

The farther your analog loop is (the length of copper wire from a digital relay station to your house) the lower your speeds will be.

If they don't offer DSL in your area - you must be >15,000 feet from a station... which would also be a good chance V90 just won't work at that distance either.

I was able to gain speed by using an external hardware based modem (US Robotics makes some top-of-the-line units), but it was still subject to weather and street lights - I could hookup at 40k on a clear day, but at night I'd be back at 33.6k speeds.

Satellite Broadband may be your only solution.

Compressed Dialup may offer some browsing relief - but it won't speed up downloads.
