After changing the name server everything seemed fine. But it isn't. In fact it is very strange.
speed test pages say I have 10 Mbps download and 40 Mbps upload (I thought it should be reverse, but several pages say the same).
Now, sometimes I open a webpage, like google, and it is here in no time. Next time I go to google it need 30 seconds. Or google comes up fast, but then clicking on a search result leads to a time-out...
Sometimes I see TLS-handshaking status for 30 seconds, another time - on the same page - no problem.
I had timeouts with google, paypal, my own site, and with thunderbird. Sometimes, when I open-close-open-close-open-close the browser window 3 times, the third time the website comes up immediatly, but then clicking on a link stops it again. Or it works. It's crazy.
Using the same wifi on my mobile phone's firefox works just perfect. So it must be something with my laptop. But what?
I tried a new virgin user with a new virgin firefox profile. The same... The problem is with thunderbird, firefox, seamonkey, chromium. I logged out and in, I rebooted...
What could it be? What can I search for?
I suspect network retries. You mentioned seeing those in Wireshark. It was possible to see them in the output from "ifconfig": Telcontar:~ # ifconfig eth0 Link encap:Ethernet HWaddr 00:21:85:16:2D:0B inet addr:192.168.1.14 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::221:85ff:fe16:2d0b/64 Scope:Link inet6 addr: fc00::14/64 Scope:Global UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:1518289 errors:0 dropped:91 overruns:0 frame:0 TX packets:1241665 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:756457351 (721.4 Mb) TX bytes:114907042 (109.5 Mb) But now the package "ifconfig" is deprecated and not installed by default. There must be another program that tells the network errors stats, but I do not know which it is. It is possible that either your wlan hardware has a weak signal, or the antenna wire became cracked, thus your phone is not affected. It is also possible the router signal is weak in your room(s). There is an app for Android that can help there: "Wifi Analyzer" from farproc. This will display signal strength as well as all other wifi signals on the spot. -- Cheers / Saludos, Carlos E. R.
