I"ve included a series of definitions for the terminology used on this page.

ISP Issues

If the issue is with your ISP or (rarely) a regional access issue, the resolution is beyond your control. You"ll just have to wait for your ISP or the internet structure lớn repair the problem.

Everything Connects via a Network

Everything about mạng internet connection issues relates to how the various networks are operating. Unless the problem is directly related lớn your computer or device (tablet, smartphone, virtual assistant, Smart home appliance) then it will involve either your own network or one that is further along the chain.

I"m going lớn use the terms computer and device interchangeably, because all that differs is how they are configured khổng lồ connect lớn the Internet.

A network is a collection of computers and other devices connected và talking lớn each other.

The most immediate network is the one inside your trang chủ or business (your home network).The next is your connection to lớn your ISP (another network).Your ISP connects to the internet (a world-wide network) through a regional collection of related networks.

Let"s have a look at how each of these may be involved in the chain of connections from your computer lớn the trang web or service you"re trying to lớn reach.

Your home Network

Your most basic trang chủ network is your computer connected directly to a modem provided by your ISP (usually via either a router or a router/modem combination).

The router provides access khổng lồ all other connected devices connected khổng lồ your network as well as lớn the Internet. Whether these devices can talk to lớn each other (i.e., share information) depends upon how the network & the devices are configured.

Your network should be secured using secure passwords for both your router & your WiFi.

Your ISP

Your ISP (Shaw, Telus, Rogers, etc.) provide you with your connection lớn the mạng internet via their own network (which includes all their customers" networks).

Your ISP then connects through a network of additional connections khổng lồ the mạng internet (designed originally khổng lồ withstand a nuclear attack by switching automatically lớn whatever routing is available).

Public Networks

Public networks include không tính tiền community WiFi networks, coffeeshop WiFi, public library networks and other similar internet connection that you don"t control.

You may be connected using your own laptop, tablet or smartphone or you may be using a public computer (such as those provided by a library or school).

If you"re having difficulty connecting on a public network, you"ll need to talk khổng lồ the staff lớn determine how to resolve the issue. Sometimes the staff have no control.

You Can"t Trust Public Networks

If you are using public access from a connection that you don"t control (something other than your home network) or one that isn"t secured properly (you haven"t changed the mặc định passwords or enabled security) then you are placing your computer and data at risk.

Everyone on an insecure (public) network such as a coffee cửa hàng can potentially “see” the information you are sending & received on that WiFi service. All it takes is some software that is easily obtained on the Internet.

Even if you"re using a gated network (one that requires you lớn sign on), unless you control that network, you can"t trust it.

NEVER vì chưng Internet banking or similar risky activity on a public network.

Cellular Networks

Cellular networks are those provided by cellular ISPs. These networks are separate from the typical trang chủ or business network and usually have relatively small data caps. Cellular networks are fairly reliable (the number of cell towers và their location determines the strength of your signal) but bởi vì sometimes go down.

Cellular service is more secure than miễn phí WiFi. However, just lượt thích your home network, everything you vị on your cell is visible khổng lồ your cellular provider unless you use a VPN.

Other than ensuring your cellular service is turned on for your device, there is little you can bởi to resolve connection issues other than to move khổng lồ an area with better reception or điện thoại tư vấn your cellular provider for assistance.

Securing Your Network

It is important that you secure your own network. It is beyond the scope of connection issues, but there are resources on this site that will help you to bởi vì that.

At the very least, you should change the default passwords used khổng lồ configure your router and connect khổng lồ your WiFi.
