How many simultaneous connections can you realistically expect on one router? Most of them are wireless. I have a printer attached to a router with 104 other users. The printer is only working sporadically. When I hard wire my laptop to the printer, it works fine. The printer is connected by ethernet to the router. This is just a residential router. I know that routers promise almost unlimited connections but that just isn't true. I think it's at least twice as loaded as it should be and is affecting the printer. What say you?
