I’ve written and talked about this subject on a number of occasions. I’ll bring these together in one place, before delving into the specifics of router configuration which prompted the subject for the meeting on Feb 4th, 2021.
For many of us home networking means WiFi, and the first article I wrote was on the subject of “Flaky WiFi” on October 11th, 2016. Members of the group had commented on their WiFi connection appearing to drop and in this article I tried to explain how all the bits and pieces hung together and how you could test your network to see it was working the way your Internet Service Provider (ISP) was proclaiming it should be!
Then, later on (January 26th, 2017), we discussed “Broadband speeds, WiFi routers (their type and security), and extenders or boosters” and as the title suggests we focussed on networking in the house and how it is provided by Internet Service Providers, such as VirginMedia, BT, Sky or TalkTalk.
I described “How the Internet works” in this post on June 29th, 2017, with links to a few videos and policy documents which hopefully explain the topic better than I could. Not much has changed since then; IPv6 is still to appear in the domestic market, so we still use IPv4 for internet addressing.
Finally, on July 27th, 2020, I wrote about “Improving home network performance” which is really what I’m going to revisit in this post.
So … what do you need to take a look at?
On your router:
If you’re using an integrated modem/router – often called a hub, typing in the IP address 192.168.1.1 will bring up a screen something similar to this …
… mine is different because I’ve disabled the router functionality so that I can use my own router – a Netgear Orbi Mesh Network – so to just access the modem part of MY hub I use the IP address 192.168.100.1. You can see from the above that only the Modem is active.
So for most users with an integrated modem/router, the first thing you need to be able to do is to access your Router’s Admin Dashboard. This article explains how to do it using the cmd prompt in Windows, but it is probable that your hub/router has an application you can start to do this, or that you can access it from a browser window. For most you would just enter the IP address 192.168.1.1 and supply the UserID admin and the password that I’ve created – the default is quite commonly ‘password’, so you ought to change that!!!
The above screen is for my mesh network, but non-mesh would be similar. Clicking on Internet will give you the ability to change some of the settings for your connection.
Of these the most useful to change is the Domain Name Server (DNS) – these are the servers that translate a URL (eg just-thoughts.com/) into an IP address. I've chosen to replace the default DNS supplied for my VirginMedia (ie 194.168.4.100) Hub (I've disabled the router functionality on the SuperHub so that it only acts as a modem) for two servers run by Google (1.1.1.1 and 8.8.4.4). The reason I've done this is that these servers are replicated around the internet and will almost certainly be closer to my router than VirginMedia which I think the closest one is in Bristol.
All the other settings can probably be left as they are. The next option is where you configure the name of your network and the channels you’re going to use.
If you don’t like the name supplied to your network by your ISP, you can change the SSID. I did to make it a little more meaningful. You should then consider changing the 2.4Ghz Channel. If you can set the channel to Auto – you should do so because generally the router will then find the best channel for your network. If that’s not possible and you have found your WiFi to be “flaky” due to you and your neighbour using the same Channel(s), try setting the channel manually to one that’s not being used. The article I mentioned before describes how you can find the best Channels for a Mac, and this one identifies a Windows Tool that does the same thing – there’s a Download link at the bottom of that documentation. Here’s an article that describes all the possibilities.
Generally 2.4GHz has a wider range of signal but lesser bandwidth (throughput), and 5Ghz the opposite – shorter distance, but higher bandwidth. On my system my 2.4GHz channel gives me 400Mbps and the 5Ghz channel 866.7Mbps.
You’ll want to look at your Security Options and make sure that you choose the best for the devices that you’re going to connect to your router. Generally, for a home network, WPA2-PSK [AES] should be sufficient.
This article from the Apple website provides a very thorough and detailed examination of what settings you should deploy for your router, and why. Worth a read, even if you’re not an Apple Fanboy!
On your device …
Make sure the security settings match that you’ve just set on your router; remember the SSID and Password you’ve created, and re-connect to your network.
And that’s about it … I hope. Questions??
