Hi, I'm trying to advise my folks on wireless routers despite being fairly ignorant myself. They have DSL, not sure which plan, but definitely not FiOS. My understanding now is that their download speeds are well below the maximum throughput of Wireless-G of 54 Mbit/s, much less N, so they don't need to buy a more expensive Wireless-N router. Is there any strong reason to recommend the N-types? Thanks. —Preceding unsigned comment added by 141.154.119.192 ( talk) 03:19, 24 July 2009 (UTC)
How do I remove colored backgrounds when viewing websites? Dark background make the text hard to read. -- Gary123 ( talk) 04:12, 24 July 2009 (UTC)
When I run old outdated software, Vista says that the software has known compatibility problems. How does it know that? I know it doesn't check the web because I'm not at a hotspot, but does it have an on-board list of incompatible software? I would guess not. Theories I've come up with so far are that it looks at the date of the software and just assumes that it will have compatibility problems and by looking at the way the program is written. The latter seems like it might take some time to analyze but the notice appears instantly. What's your take? -- penubag ( talk) 06:35, 24 July 2009 (UTC)
The story so far: I have to display mathematical stuff such as matrices , logarithms etc in a word document. Initially I made them in mspaint and inserted these images in word. It is too time consuming and changes cannot be made easily so I googled for a tool for working with matrices and found http://math.exeter.edu/rparris/winmat.html. This tool has an option of creating .tex document, which I found out to be latex format. The trouble is iam not able to view the matrices with this tool http://www.exomatik.net/LaTeX/USBTeXEnglish#toc3 . --- Nothing has worked yet as I have not found a way to easily create mathematical formulas and equations that can be displayed in a word document. Please say how it is done with free tools. —Preceding unsigned comment added by 131.220.46.25 ( talk) 11:51, 24 July 2009 (UTC)

No worries everyone, I found out what the problem was I had the incorrect hash bang in the .pl file. Thanks everyone!
There is a plain text file and contains thousands of lines in it. It looks like:

At my sister's house they have a single wireless modem/router. The signal is pretty good downstairs and in the garden, but the signal is pretty weak everywhere upstairs; and in a couple of bedrooms the signal is so weak that a reliable connection cannot be maintained. The wirless point is located in a single storey extension towards the rear of the house, and I believe the quantity of pipes, wires and other stuff in the space between the ceiling and the floor upstairs is partially shielding the upstairs. We have already tried a wireless range extender but it wouldn't communicate with the modem/router - according to Linksys technical support, the range extender is only compatible with a limited number of their products and my sister's modem/router is not one of them. We could run wires to the upstairs, but doing so would require extensive drilling, disturbing newly laid hard floors, and the kids would all have to connect to the wired connection.
In a couple of weeks (while they are all away on holiday and I'm looking after their large number of pets), I will be doing some experiments, placing the wireless/modem in various locations to see if I can improve the situation upstairs. One alternative though is to replace the current wireless-G modem/router with a newer wireless-N product. My question is: if the receiving equipment (ie. laptops and various wireless cards) is still only compatible with the wireless-G standard, will we actually get any increase in the effective signal strength upstairs? In other words, would I be better off saving my sister the £80 that it would cost to get a new modem/router, and instead get a long drill to pass the cables upstairs?

I have two computers, both with ethernet ports. My internet connection comes directly from the router via an ethernet cable, but there is only one port on the router so only one cable can be connected to it. How can I get internet on both computers? —Preceding unsigned comment added by 82.43.91.128 ( talk) 18:40, 24 July 2009 (UTC)
The idea about connecting the second computer to the first sounds good! Both computers have two ethernet ports themselves. How would I go about sharing the connection between them? And would the second computer act as if it was connected to the internet directly (ie would incoming connections like for gaming and stuff go to the second computer, or the first computer only?) —Preceding

Ok thanks I'll give it a go. Will the second computer be able to receive incoming connections (like a game or web server)? Or will those connections only go to the first computer (the one directly connected to the internet)?

My brother's computer, which generally has an issue with accumulating malware, is deciding to be a pillock. He can boot it up and log in A-OK, but the computer suddenly restarts within three minutes after doing so, regardless of the account he logs onto. He's certain there's no bugs on the rig because he ran MalwareBytes last night before he went to bed. He is running Windows XP. - Jeremy ( v^_^v Tear him for his bad verses!) 21:43, 24 July 2009 (UTC)
