Default Strange Store behavior with downloads

This mornin i noticed a strange thing, i had lots of wifi problems now i am on ARHD 33.1 with lyapota mod pack, the fix in the mod pack seemed to have fixed the issues a bit, now i get my wifi and apps work correctly, but now when i install apps through the store it seemed very slow then just by luck i pulled down the notification bar and got surprised on the notification bar the download was going normally it showed 90% while the store was 3% and whe done it installed before the store reached 100%. what the hell

UPDATE: Well my wifi still is ultra slow, i hope there will be something done about it
