Houston We Have A Problem 138, 29/01/11
I read recently that the average broadband
download speed in the UK was a whopping 6.8Mbps. I live in Harlow, a town of
some 80,000 people and I can only achieve 0.58 Mbps. This is an increase from a
previous 0.11Mbps following the replacement of my wireless router. Would I get
a faster speed with a non-wireless router or is there no hope for me?

Without knowing what type of Wi-Fi system you
are using and the speed your broadband provider claims you could be getting,
it’s difficult to say what’s wrong. However, assuming that your service is
supposed to be 1Mbs or faster, say, then there may be a data bottleneck at the
exchange end of the connection or there are problems with the copper wire
‘pipe’ through which your service is delivered. The three most commonly used
Wi-Fi protocols (802.11b, g & n) have theoretical top speeds of 11, 54 and
200Mbs respectively. In the real world actual data transfer speed between
wireless routers and PCs will be a fair bit slower but it should still be
faster than most broadband connections. There is an easy way to find out if
Wi-Fi is slowing things down and that’s to bypass it by connecting your PC directly
to the router using an Ethernet cable. This type of connection has a nominal
data transfer speed of around 100Mbps, so if your broadband speed tester
indicates that it is significantly slower than what you are paying for – and
you should check it at several different times throughout the day – then it’s
time to have a chat with your ISP.
I've recently bought a new laptop with Windows
7. I am getting on with it, but wondered if it is possible to do something
about the feature that locks the computer after what seems an irritatingly
short period of time? I tend to leave my machine on all day, just occasionally
checking my emails or web browsing, but I'm finding that after just a few
minutes of inactivity, Windows has locked me out and I having to re-enter my
password. Can I disable this feature or extend the period before I'm locked

The first stop for anything that affects the
way your PC looks or behaves is Control Panel, which you will find on the Start
menu. Click on the Power Options icon (if it’s not displayed click the link
next to ‘View By’ and select Large or Small Icons), then Change Plan Setting.
Here you can adjust the times it takes for the PC to do things whilst on
battery power or when plugged into the mains. While you are at it click Change
Advanced Power Settings and uncheck ‘Require a password on wakeup’.
HDD to DVD
I have recordings stored on the hard drive of
our Virgin V+ box and I want to convert some of them into DVDs. There is a
facility on the V+ box to enable this but what else do I need? I have a Windows
7 laptop, with a DVD recorder drive, could this be used?
David Bush, by email
For various copyright and rights management
reasons Virgin V+ and Sky+ hard disc drive recorders won’t allow you make
direct digital copies of stored programs but there’s nothing to stop you
recording the analogue video (and audio) outputs. By far the simplest method is
to connect your V+ (or Sky+) box to the AV input on a DVD recorder using a
If you want to do it on your PC you will need
an AV input module, which plugs into one of your laptop’s USB sockets and takes
care of the analogue to digital conversion. You will also need some suitable
recording, editing and DVD authoring software. There are plenty of free and
commercial programs to choose from but if you want to keep things simple then I
suggest a bundled hardware and software package like the ClimaxDigital VCAP302
VHS to DVD (around £17.00) or Roxio’s Easy VHS to DVD (around £60) – both available
from Amazon. By the way, whichever method you use to make your DVDs, the
conversion from digital to analogue and then back again to digital means that
there will be a small but noticeable drop in picture quality.
When away from home I use a Vodafone 3G Mobile
Connect USB dongle. I find that I can receive my emails but cannot send them
and it shows system error. My laptop operates Windows Vista.

In most cases incoming emails are stored on
your home Internet service provider’s POP3 (Post Office Protocol) mail server
and you can access them from anywhere using any type of connection. Outgoing
mail, on the other hand has to be sent through the SMTP (Simple Mail Transfer
Protocol) mail server of the service that you are currently using, whether it’s
a 3G mobile network or a wi-fi hotspot. There are two solutions. You can change
the SMTP address in your email program, or do what many travellers do and
access their mail through an Internet browser using a webmail service like
Gmail, Hotmail, Yahoo Mail and so on, and most of them can be set to pick up
your POP3 messages.
If you want to continue using your email
program then you need to find out the service’s SMTP address. There is a list
of the main UK 3G SMTP servers at http://goo.gl/Ak50V.
At Wi-Fi hotspots and in hotels etc. you’ll have to ask whoever is in charge
for the SMTP address.
To change the SMTP address in email programs
like Outlook Express and Windows Mail etc., go to Tools > Accounts, select
your account, click Properties, then the Server tab. Make a note of the
existing SMTP address then replace it with the right one for your service,
which in your case should be smtp.vodafone.net. Don’t forget to change it back when
you get home.
