Cisoc and Plusnet related??
Had a frustrating day with the idiot bosses new Plusnet router last month "Router is Pre-configured for your".
Yeah, right, preconfigured with SOMEONE ELSE'S PERSONAL INFO!!!
Since it takes the stupid box a good 30 minutes just to wake up/reset, then another 30 minutes get an ADSL sync, I wasted 6 hours on the thing (including 90 minutes on hold with their tech support line), before finding a PnP format letter with the correct name/password on it (buried in pages of marketing guff, so no-one realised there was anything important included).
(Just signing up for a YEAR with Plusnet, because they offered £1 per month off of line rental is enough to qualify as a sub-moron).
