I am sorry for late answer. Hard to say what could be wrong. Dosbox supports win9.x unofficialy. But I personally dont have problems with win95 and I play various games. Problem may be in drivers, magic dosbox has not implemented ethernet or voodoo card support. I recommend to follow video guide on our youtube channel and install fresh win95 based on this guide. 1.5 year ago I installed win95 this way and until now I use it on tablet with mDosbox without big issues.
The video guide has three parts.
