Networking challenge quiz for school IT and computing fair

Thursday, February 2nd, 2017

In the UK, Year 9 (age 13 to 14) is an important stage which can influence the student’s future career. It is during this year that the students first decide on what subjects to pursue, and in particular whether they will continue to study computer science. I recently attended a computing and IT careers fair […]

Setting up the Raspberry Pi as a host wireless hotspot

Wednesday, November 27th, 2013

This guide is how to turn a Raspberry Pi into a host Wireless WiFi hotspot. First what does that mean? This will not turn your Pi into a wireless router (although you’d be half-way there), but instead provides a way to connect and control a Raspberry Pi using a dedicated wireless network. The reason I […]

Raspberry Pi Christmas bundle – running Rasbian Linux and Raspbmc

Sunday, December 30th, 2012

I was intending this blog post to be rather different, it was intended to show how easy you could put together your own Raspberry Pi bundle, but it didn’t go quite as smoothly as planned. Fortunately it all turned out in the end, and I only had to replace one item, but it was a […]

Review of the Android mobile phone operating system (HTC Wildfire)

Sunday, March 6th, 2011

It’s Free! It’s not about the cost, it’s about being free! Not another mobile phone review This isn’t a review about a mobile phone handset – Google shows that there are already about 2 million of those for this model1, and it’s not just a review about the Android operating system – there are about […]

Ubuntu Linux – slow wireless network speed – force adapter speed

Friday, February 18th, 2011

In the past I have had very poor networking performance on my wireless network (Wireless LAN / WiFi) which appeared to have been caused by interference from other networks. I’ve since upgraded to a Belkin N Wireless Cable router which has certainly improved performance, but I notice that I’m still get some quite slow WiFi […]

Belkin N Wireless Router F5D8236UK4 802.11n cable router and 4 port switch

Wednesday, January 5th, 2011

I’ve been having some problems with my wireless Wi-Fi network connection at home for the last couple of months. Most of the time the network works fine, but occasionally the network slows down to the point where it becomes unusable. This happens mainly in the evening and I believe is due to interference from a […]

New Year 2011 – Website review

Friday, December 31st, 2010

Happy New Year This year I thought I’d look back at some of my involvement in the Internet / websites and how these may change in the forthcoming year. My first website was back in 1994 when I created websites for Hull University LINKs and Hull University Canoe Club. This was very early in the […]

Wireless networking – Wifi slow or broken – try changing channel

Wednesday, November 24th, 2010

In the good old days of wireless networking the world was a wonderful place. You bought a wireless router plugged it into your broadband and it just worked. There was an issue of not enabling security, but that just made it easier for others to borrow your network (good or bad depends upon your personal […]
