Bear in mind these public speedtesters can be wildly inaccurate.

The only way you can be sure of your actual connection speed is testing it with a server you can ensure is not suffering congestion and has a sufficiently fast connection.

You running off a fiber optic connection or something? I mean I know Europe connection speeds are generally high, but wtf @ 1Gbps o.O

Sure you don't just have a gigabit router/switch?

speedtest.net doest not support packet windowing, so results for a router like a watchguard will not work at all. Best bet is to ftp from a bigger pipe then yours.

Now from what i gather here your connection is ADSL? Be advised that with those type of connection, capping your upload will significantly (rougly 60%) downgrade your download speed.

It's pretty obvious these aren't designed for testing high bandwidth links since they are flash based and don't allow enough time for rwin tuning to apply. As long as you pick a nearby test server, you should be testing your line speed pretty accurately up to about 100mbps. If you have over 10-20ms ping to a nearby server (<200 miles) something is messed up with your connection or ISP.

www.pingtest.net is arguably more important than a speed test since high ping and packet loss will greatly decrease speed.

I have a 25Mbps with Shaw (which is the fastest ISP in Winnipeg) but I only get around 15Mbps on Speedtest and only get around 2.5Mbps on actual downloads.

I hope you meant 2.5MB down because that would be a pretty crazy downgrade for your down speed D:


Oh woops, yes sorry XD.
I re-read it just now.

have you tried calling your isp?

there could either be a problem on their end or a problem with your physical setup at home.

looks like a modem or hardware bottleneck, also like a lot of people said u aren't guarantee the speed they offer, also like a few others say. Is it MBps or Mbps ur looking at.

Gigabit Ethernet at university (As a student, I don't get more, I think the whole facility is connected with 5-10GBit/s). At home, I'm connected with just 16MBit/s.

Anyway, back to topic: One thing you can measure without fuss is the RTT/delay/lag/ping. Just use traceroutetraceroute (tracert on Windows) on any random URL. Note that some intermediary hosts may drop or throttle ICMP messages, so repeat your measurements if it seems unrealistic. Most US ISPs should have pretty good names for their routers, so you should be able to determine where the packets leave your ISP's network. Otherwise, just traceroute 2/3/4 different targets and look where the routes diverge. For online gaming, bandwidth is pretty negligible, it's the delay that counts.

From qwest we assume ADSL
So in other words we are looking for this data that can be found on your modem. The 200 ping is that the closest you are to a sever? that seems quite far vista and windows 7 don't require any tweaking but xp does.
