UP/Down speed test oddity

I'm using wifi with a 100 yard plus link distance.
I did a speed test at;
http://www.speed.io/index_en.html

The result was Download 29kbits/s and Upload 303kbits/s .

Download very slow

Download is usually over 3000kbits/s, Upload 300 to 330 kbits/s.

Computers been slow lately, and takes forever just to load
everything to start.

Any thoughts about this situation?
Mike

Glad to see you all have your senses of humor in good shape :-)
I just thought it was odd that I had a slower download than upload
usually download is 10 or 15 times faster than upload.
Then, I wondered if it might be related to my slow loading
at starup of the computer.
I'll look into the software later today, when I get some time.
Crystal ball data point coming soon!
Mike

Telephone your ISP and tell them your problem. They can run tests and
diagnose problems far more quickly than you can. I had a problem when first
connecting with my ISP and I called them up. They told me to turn on my
computer and connect to the Internet. 2 minutes (or there about) they told
me exactly where the problem was and it was the telephone line into the
house. A bit later the telephone company tech showed up, fixed the problem
and all has been well since.
