A quick simple time line for loading page.

You type http://www.somerandomsite.com into address bar
PC sends request to router or over internet to convert the domain name to an ip address - first delay
PC gets DNS request back now talks to http server
PC gets back the basic HTTP page
Web browser parses this page and uploads the requests for all the images and other content on the page
If content is from other sites/domains then another DNS request may be needed.
This contents comes back to your web browser and is drawn
Viola you finally see the complete webpage.

A very slow upstream can delay the requests for all the elements, and while you may type one http address, the web browser may have fetched MANY elements in the process of getting the data to draw the page.

In simple terms, everything over the Internet (or any network) is a two way conversation.

Sort of
"Can I have that?"
"Here you are"
"Got it O.K."
or variations on this.

The requests and confirmations tend to be very small.
The data requested tends to be quite large.

So this is the basis for the more technical descriptions using acronyms and specialist tems for the different requests and responses.

Oh, and the tests you have described so far seem to indicate a local problem with your wireless connection as the wired connection still seems to perform as expected.

As you work O.K. with next door's router the main suspect is your router.
Causes could be a router hardware fault, or interference from another wireless source.
You say that you can easily see next door's router from your house but not vice versa.
This seems to suggest that your wireless router has a poorer signal and/or is suffering more interference.

The best way to progress is to swap around the channel your router uses (try all the numbers) just to confirm it isn't interference or you can't avoid the interference. If this doesn't help, borrow another router or get a replacement.

Why is download O.K. but upload not?
No real idea, apart from a possible fault in the radio receiver on your router where it can receive the small messages O.K. (request and response) from your PC for downloads but tends to fail when receiving larger data messages from your PC destined for uploads.
I suggest the receiver because the transmitter seems to be sending the larger data blocks O.K.

Thanks for the continuing replies.

After trying various things, including resintalling the operating system and all applications on my laptop (just in case), and still not resolving the issue of slow upload speed, I reset the router back to default settings.

Voila, I have now got back to the .35Mbps upload speed that I had before it slowed to about .05Mbps.

I have no idea why it is now ok, but thanks for confirming why a slow upload speed would result in web pages being displayed on my computer.
