How do I find out how may GB left on my wifi?

[Richard]

There is actually no monthly limit on WiFi. WiFi is just another method of connecting a device to your router as an alternative to using Ethernet. The limit is on your actual Internet connection to your ISP.

Some ISP's show you how much of your monthly allowance you have used when you log on to your ISP account; however, some ISPs do not offer this facility.

Log on to your ISP account and see if there is a monthly usage indicator. If you cannot find one, then give your ISP a call and ask them how you can tell how much of your limit you have used.

By the way, Christopher is wrong. Any activity on your Internet connection counts towards your monthly limit. This includes looking at things on your ISP account. Compared with many downloads such as videos, displaying a web page does not normally impose to much of an impact on your monthly limit. However, if you look at lots of things on the Internet, then it can become significant.

I hope this helps.
