G’Day folks,

Just reading through the recent thread started by Fred Stratton: "Correct syntax for cake commands and atm issues.”

It appears that Fred’s configuration is for a WNDR3800 running Cero/Lupin connected via an ethernet segment to a DSL modem to the outside world.

My setup is  as follows. I have a Lantiq based TPlink TDW8970 as my actual DSL modem to the outside world running OpenWRT BarrierBreaker (and using the luci sqm scripts from that release). That TDW8970 is connected via an ethernet segment to a WNDR3700v2 running cero 3.10.50-1 (which is my router, leftover from using the junker DSL modem from my ISP that used to sit where the TDW8970 sits now).

My DSL line-sync rates are 3712 Kb/s down and 448 Kb/s up. (I live out in the boonies, and refuse to do business with Time Warner Cable, so Frontier it is, complete with crappy speeds). As I understand their network topology, this isn’t a central office DSLAM, but a fiber-to-the-node thingy. The upshot is that unlike my last place with DSL to a central office, I have very stable line-sync rates with noise margins (as reported by luci) of about 38dB down and 28dB up. (If only Frontier would sell me a higher speed link, but I digress.)

So, If there is any interest from the group in testing cake on such a marginal DSL configuration, I’m ready to give it a shot, but will need some instructions. Be aware that the TDW8970 is fairly constrained for overlay filespace — I currently have only ~800k free — so the install might be nontrivial.

Cheers,
