Hot Hot Router

[#1]

I have just become a Plusnet broadband BBYW Op 2 user (2 days ago). Everything works fine etc etc and set-up was easy and straight forward using Plusnets guides... However, there is one issue. The wireless router that Plusnet supplied (D-Link DSL2640B) although working correctly seems to be running extremely hot to the touch, so much so that I'm tempted to turn it off when not on the internet.
Qs. Is there a problem with my router if it runs so hot (I did read a review on some on-line store where someone mentioned the same thing), and is there a problem with turning it off when not in use (especially during this initial 'setting down' period) or should it be ideally be kept on 24/7.
Any advice would be greatfully received. Regards Brum.

The router will get reasonably warm/.hot but should not get dangerously so.  Is it stood up or in a position where it is reasonably ventilated?  Many people leave their routers on 24/7 and many turn them off at night.  During the initial 10 day training period it is usually advised to turn your router off and back on again at least once a day.  Perhaps in your case you might feel better turning it off overnight and then switching back on again in the morning (you'll often find that you can connect at a better speed during quieyer times like morning).

The router is sat on a flat desk with ventilation slots cut into the rear of the top panel and the front of the base panel. However the four rubber feet which are supposed to keep it clear of the mounting surface are literally only 1.5mm high! I also didn't realise that you are mean't to turn your router on/off during the initial 10 day period, I must have missed that in the set-up blurb. I just assumed the opposite and that I shouldn't mess with it while it finds it's optimum speed (Although I'm more than happy with my initial download speed given my distance from the local exchange). I think I'll take up your suggestion and turn it off at night, that way I'll hopefully save the desk surface from being scorched!!.

If it is just a quite warm that is fairly normal. As long as there is proper airflow around it (and it sounds like there is), if any part of the case is too hot to hold your hand on comfortably then it is breaking safety standards and you would be reasonably entitled to ask for a new one.

Hi,
My D-Link also run HOT...
Try turning the wireless stransmitter power down, this should help.  You'll need to do some checks to see that your computers still operates OK and is not losing signal.
My wireless cards are Cisco 350 and there's a signal level meter within the software which I can use to check signal levels.  Alternatively you can download NetStumbler and that will show you the D-Link's wireless signal level.
To access the D-Link's wireless power adjustment, access your router via a web browser as usual.  Click on Advanced at the top then click on advanced wireless on the left side.  You'll see 'transmit power' at the top.  Click on the little down arrow and select an alternative power level.  These routers usually default to high power.
You 'may' find that reducing the power level will only make a difference if your PC is a fair distance from the router - but it should then run a bit cooler. 
(an added bonus is that the guy next door might not be able to 'hear' it and pich some of your bandwidth - assuming you've not got it encrypted !!!) 
Hope that's of some help,
John
