guys please help me , it happens when ever i want. i speed test from speedtest.net and i get speed 0.89 mbps ( which is good for me) but if i download something , down speed is 2 kb. if i play a video it buffes so slowly that it takes ahour.
1 thing more, this happened few days ago on my laptop, so i started using internet on my pc , this this stopped and i got high speed.. but now after some days it has started again
When comparing speeds, remember to divide your speedtest result by 8. 0.89 mbps is around 101KBps.
Download speeds depend on many factors, inclduing the modem/router, traffic through your ISP at the time, and the type of download, just to name a couple.
What type of download is it? Are they torrents? These can often be slow.
Are downloads slow from everywhere?
You mentioned video buffering; Do you have downloads going at the same time that you are trying to view a video? Are there other people sharing your connection (eg other family members)?
You didn't say if you had tried rebooting the router/modem, or if you had been in contact with your ISP. These would be among the first things to try.
As you haven't stated what you have tried, I'm going to assume none of the following have been tried. Apologies if you have tried/tested the following.
If you plug a phone into the same wall socket at your modem do hear any noise/static or is is sound quality very poor or low volume? These might indicate physical line problems, which your Telco would need to address.
It's also possible the equipment at your local exchange is in need of a reboot. This is often referred to as a "Port reset". Your ISP can do this for you.
Other things you can try is replacing the phone and ethernet cable (if you are connected by cable), or replacing the line filter if you have one. If you have multiple devices on your phone line remove everything except your modem/router.
If you have a DSL connection you know that the speeds will vary dramatically from one hour to the next. But 2KBps is poor in any situation.
Have you tried doing ping and tracert to various sites? You ISP may want this information to place a fault report with your telco.
copy and paste results into an email to your ISP
ping
www.google.com -t (Stop it after a minute or so).
ping
www.yahoo.com -t (Stop it after a minute or so).
tracert
www.google.com
See how you go with the above. Get back to us if you get no joy from your ISP/Telco.
