Im having a very strange stall of my internet connection to all of my devices (tablets,desktop,smartphones). The provider seems to work fine, but the issue is amongst the devices, their internet connection seems to stop working but I can't figure out why! If I reboot the modem/router it all works ok but after some indefinite time I get the stalling again! Could it be some incompatibility or ipconflict that might be causing this? And if so what can I do about it?
A pretty important question:
Do you have a full duplex Internet connection?
If you use a DSL line, many older phone exchange boxes (on the ISP's side, not yours) can't properly handle simultaneous upstream and downstream traffic. This results in network timeouts whenever something on your side attempts to upload a steady stream of data - for example an iCloud backup from a phone or iPad.
The only way I've found to get around this problem unless you can convince your ISP to upgrade their gear (no, it won't happen), is to force your own router to cap upload speeds if it has that ability.
Run a speed test on your connection with nothing else connected, then configure your router to allow uploads at no more than 75% of the maximum upload speed.
