lan file transfer just crashes internet

[Need_Not]

i setup my old laptop as a file server i guess you could say. it doesn't transfer very fast and im assuming it must be the hardrrive read/write but aside from that yesterday i was backing up a project that took 30 minutes durning the 30 minutes i couldn't even watch youtube without buffering every 2 seconds. then i tried another device and it said obtaining ip adress for like 5 minutes snd wouldn't connect but the file transfer didn't stop which is good.

 

this morning i tried playing a game while downloading a 75mb video to my phone amd instantly got disconnected from my game and then like 10s later everything went offline.

 

why does this happen? my internet speed may only be 10mbps down and 2 up but this lan the bandwidth limit should be the hardware not my isp

If either device is connected over WiFi it could easily be overloading the router.

 

A lot of routers aren't really powerful enough to handle WiFi at full speed and once their CPU gets maxed out it can cause the issues you describe, as there is nothing left to service the actual routing.

Of course if it goes offline and takes a while to come back AFTER the file transfer is finished, the router could be buggy and outright crashing/rebooting.

but it's not even full speed it's transfering at 2-3mbps

Why don't you use cables and see what happens?
