The Bees were held 2-2 by strugglers Bury on Saturday after conceding a late equaliser and it means Rosler's men have collected just one league win since the turn of the year.
However, they are only five points off the League One summit and their manager is confident they will wake from their slumber sooner rather than later.
"We have a blip in form, but we are right up there," Rosler told the Kingston Guardian. "This group of players has to keep on doing the same things, believe in the way we play, not lose our confidence if results aren't going our way and be mentally stronger to win football games.
"The players are playing to their capacity, to their ability. Some of them are very consistent over many months.
"We have a blip of results, not form, now and we have to turn that around and start winning again. But there is more to come from this very young team."
