P400 Broken Packets, 1/4 speed internet :-(

[bodhibody]

Hi I have recently got a Lenovo P400 and I did a speedtest on it with my wifi after I got it and it was about 4MB/s (30Mbps) which is 1/4th of my usual speed.

The worst:
My tabs instead of loading all at once I have to load each of them one at a time because some of them do not load (too many connection attempts and network packets discarded?). :-/

I would tolerate the 1/4 speed reduction but the above problem is horrible. Sometimes I will click on a page and it will load only text or only part of a page! I have to click reload and it'll load the page.

Any ideas on how to fix this? I've uninstalled my antivirus, uninstalled and reinstalled my latest wifi drivers, doing speed test each time.
I'm doing a malware scan now and it showed 2 things detected... still running.

More info:
--I'm running Windows 8 64bit
--My other computers when speed test done shows 30-40Mbps

It wasn't any malware. Just two trainers for games.
Thinking all this may have something to do with the way packets come to this computer...

And I forgot to mention that the speed is what it is supposed to be (30Mbps) on the other computers at my house including my phone -_-'

ping gateway to see if you loose packets.

No bytes lost.

And that was weird. Downloading a test porn file off piratebay fixed my internet connection.

From 5mbs to my good 'ol 30mbs+.

I clicked "forget connection" and when reconnecting I changed to "turn off sharing."
I think this may have been the entire issue.

Ugh nevermind. It keeps going back to ~10mbs after I reconnect.
I notice that the signal is "very strong" and at 180-300mbs when I get my 30mbs+
whereas "strong" and ~"150mbs" when I get ~15mbs.
Edit: nevermind that's wrong too and varies

OH well. It's good now for the next hour I guess. At least I know to reconnect when I need fast internet. :-/
Lame that this doesn't happen on any of my house computers or phones. All get stable access to that full blast 30mbps. Mind be a wifi card thing on this new laptop.

So yeah to conclude this thread:

My 1TB HD RPM is 5400 (slow) and I've been doing a lot of PDF processing/program installing/uninstalling in the BG whenever I'm testing my internet on and off.
My HD was getting USED to the max.

That's basically why the internet was slow sometimes and fast sometimes, the test files themselves couldn't load onto my computer fast enough.

I've gotta get a SSD. Maybe next year they'll have 500GB SSD for $100.

Also FYI if your pages get broken in Chrome, make sure to disable "predict network" option in advanced settings. The prediction itself slow it down.

How about "Lost waves!"

Ping says nothing, except that connection can be established...

I would try to find better position for laptop, to rule out "deaf corner", or problematic position...

If there's statistics (some wireless nic-s have it), look at
- retransmitted packets, that can be reason for low throughput...
- packets received with CRC-error, can be reason for low throughput...

If better position could not be found, than sw-problem, or hw-problem...
