Windows 7: W7-Internet performance-TCP connections

TIME_WAIT means one side has tried to close the connection (usually the client), but the server has not yet responded with an acknowledgement of the close request. These connections will ultimately timeout when the connection times out.

The internet service (8Mb) is so slow that to open a webpage like facebook, it takes about 2-3 min.

With the same laptop, in my neighbor house with a servive of 2Mb it takes 5-10 s.

Well, that's simply a problem on the end of your Internet service provider. Explain to them that you tried the same PC on another connection which worked well.

Ask them to send a repair crew to look into it.

In looking at your ping times and tracert, it does appear that your latencies within your ISPs peer route in the US (integra.net) are really very slow. It would be interesting to see you run a tracert against www. google.com and www. microsoft.com, to see if you also go through those same routes from Portugal into the US.

The fact that the same exact machine on another internet connection doesn't exhibit the symptoms means that it really isn't the machine, it's the network connection (and in this case, it's likely the actual route the packets take that is the problem). High latency means a high likelihood of TCP timeouts, window size shrinkage, TCP resets and packet resends, etc. It can really slow your browsing, much more than having low bandwidth or throughput.

Netstat isn't a useful tool for diagnosing internet speed problems. The number of tcp connections is not a useful metric either. Whoever told you that you had too many tcp connections was either ignorant or making stuff up to fob you off.

On my machine I regularly hit 1000+ tcp connections, most of which will be either internal or half-open and it has no effect whatsoever on the performance of my 2Mb DSL connection.

Well, thatīs the problem. The portuguese internet supplier "Optimus Clix" does send anyone because they say that's not a clix problem but a laptop problem of many TCP connection, and that's spayware "eating"bandwdth...can you believe this guys?

What do you mean by; problem on the end of your internet service provider? Could be router manfunction?

I can believe the people you're talking to at your ISP are script-reading morons, but that's about it .

It means that they aren't giving you the service that you are paying for. Call them up, explain to them that you have tried the same laptop on another Internet connection without any problems.

Tell them to send someone and stop wasting your time. Ask for a supervisor if necessary.

Let us know what happens.

In addition, you acquired something on the subject of IPs as well as the potential reasons for networking issues. The fact is that, you can find here a lot more details about IP Address 192.168.l.254 and its particular capabilities, once you search this address through the internet.
