Solved download speed different from speed test

aha ok i cant wait to buy a new n router .

as my isp said i pay 50$ for 20 MB/s and a limit of 30 GB

after many downloads i can tell that the speed of download start at 6 Mbps after 1 min it drop to 1 Mbps and after 1 min its drop to 0.5 Mbps and stay at 0.5 Mbps to all download finish . and while im downloading i test the speed with speed test and it tell me its 6 Mbps
so weird

and guys is that true that wep encryption not good with win 8.1 ?

sorry for my english frensh educated

thank u guys

It could be that you have already reached this 30GB limit and your ISP is now throttling your connection speed.

WEP is not only outdated but it isn't very secure although it should work OK, I wouldn't expect much from it combined with wireless g.

The max Wireless G speeds of 54Mbps, in theory shouldn't be slowing the connection to the ISP, experience has taught me that theory and functionality don't always work out like you would expect.

Assuming this connection isn't being throttled then most likely going to a newer wireless N router may help, or at least may get you closer to what you are paying for. No guarantee's but it might help and certainly can't hurt, it would also be more secure and you would also gain up to 6 times faster LAN speeds.

ISP vs Carrier

Hi,

Just to be clear, is your ISP the same as your line provider.??

My ISP is EE, the line is provided by BT they handover to EE
When I speed test to BT Wholesale, I get almost 24/7 stable results
However once EE start managing the traffic, and then the internet it'self
well it's another story.

Using any internet speed test will give different results.
Half the speed...
