said by imanon :Lake Zurich, IL here (actually closer to Mundelein but I am told we're off the Lake Zurich headend) and even after rebooting modem, still stuck at 25Mbps. Modem did get a new firmware file when compared with earlier in the year...
Old was SB_KOMODO-1.0.6.6-SCM00-NOSH
New is SB_KOMODO-1.0.6.8-SCM01-NOSH
Old was PSPU-Boot(25CLK) 1.0.12.
New is PSPU-Boot(25CLK) 1.0.12.18m3
...not sure which, if any dictates the speed.
The firmware update is
completely 100% unrelated to the tier speed increase.
