The WiFi keeps disconnecting...

I get to upload large files on Google Drive but there's just too many of the files and they are a bit large i.e. 4 Gb. Something - not sure if this is the browser or Google Drive itself keeps returning an error message reading 'Upload paused (offline), and, my WiFi, which is controlled by the operating system and the internet service provider along the way loses its connectivity.

I start worrying whether my neighbors are using the same frequency, and, after trying to restart the connection by signing out and signing in again the same thing happens all over. Usually when this happens I assume network traffic is not going to make my life easy for me to upload files over WiFi.

Does the architecture envisage software and other underlying solutions for these little problems?

Download the free version on inSSIDer, scan the airspace, more than likely you're using the 2.4GHz spectrum, whch allows for 3 non-overlapping channels to be used by your home router (1,6 and 11) most routers have an "intelligent" channel scan where they see what channels your neighbours are using and move to a different channel to eliminate co-channel interference. This never works. period. log into your router after running inSSIDer, find what channels are most heavily used, I tend to find that most home grade routers like channel 1, but they are not restricted to this, so they could be on any of the 14 channels available (depending on where you are in the world!) so if you see lots of routers on channel 1, move your router to channel 6 or 11.

The thing to remember with wifi is that it is a half duplex shared medium, no two devices can talk at the same time, so if the airspace is super contested and all the wifi around you is on channel 1 they wait, they listen to see if anyone else is broadcasting, then they broadcast if the airspace is free, but if they see another device talking, it waits and waits and waits for a free period in which to transmit, so moving your wifi channel to one that isn't heavily used is really beneficial.

Preferentially we would use the 5GHz spectrum, its faster, much much bigger in terms of usable airspace, the downside is that it doesnt travel as far as the 2.4GHz, it struggles to go through walls. The 5GHZ has 24 non-overlapping 20MHz channels compared with 3 in the 2.4 spectrum... If your router is so cheap that it isn't dual band, I'd advise sourcing a dual band router! :) Happy wifi-ing !
