Firefox became very slow and strangely waits for 192.168.101.1:8888
Firefox started loading urls with a huge delay despite having a fast plan (70 MBit download)
Also in status line at the window bottom it sometimes prints waiting for 192.168.101.1:8888
My laptop is connected via WiFi with no dns-nameservers configured in /etc/network/interfaces and my router has wired connection to the ISP.
Who does that IP address belong to? Why does my browser wait for that strange address?

UPDATE2:
I've conclude that my laptop was hacked.
Here what shows in the conection telnet 192.168.101.1 8888 the command GET / HTTP1.1
Look at <LI><A HREF="data_durablis/">data_durablis/</A>. I created that folder by myself, thus these links to my root dir folders, not typical linux install folders.

192.168.101.1 is a private IP from RFC1918. Meaning it's not routable through the internet. No hacker (on the internet) can use it. With that said your ISP is using 10.134.0.1 & 10.254.246.49 inside their network which is also a private IP RFC1918. So your ISP is using a private IPs inside their network, thus they're the only ones that could route to 192.168.101.1
The http site that's hosted on 192.168.101.1 8888 is odd but are just a bunch of links to a typical linux install.
clamscan output just shows a bunch of windows viruses (from what i can tell)
So from what i can see, the most logical answer is your ISP has a fast (70 GBit???) connection to their LAN, but a slow pipe to outside Internet. To speed things up your ISP is running a proxy server and tunneling all http requests through 192.168.101.1:8888
