The Fetch is equipped with a Browse program of equal rating and a personafix program (both also run on the processor)
Since both run on the Fetch processor the commlink's statline doesn't matter. The commlink being able to get a signal to the matrix does, however, so Signal 1 could present a problem in areas with lots of vegetation, the slightest amounts of antiwireless paint, or a hill. [Vegetation and hills reducing signal is per Unwired and at GM discretion so YMMV]
Speaking in generalities if you can afford a 4000 nuyen fetch module you should really invest in a good commlink with no fetch and a browse program (preferably with the Optimization-3 Program Option) and search the matrix yourself until you can afford an Unrestricted Agent to act like a Fetch module. The commlink is a solid need while the Fetch is lackluster at best and expensive to boot.
