Issues with my Laptop & Wifi/Internet connection

for some weeks now I experience problems with my internet connection in the morning.
 
 
 
In detail:
 
I’m working on a customer’s site with an installed Wifi connection to the outside world (Telekom Router).
 
At the end of each day I shut down my laptop (Dell).
 
In the morning I boot the laptop, and immediately have a very poor internet connection, sometimes it fails at all.
 
After a reboot the internet connection works flawless for the rest of the day.
 
(very seldom it works right from the start without a reboot, or on the other hand it needs a second reboot – but in 90% one reboot will fix the issue)
 
 
 
Attached some screenshots of good/bad scenarios.
 
 
 
Please advise. I’m happy to provide any information you may need.

I had a similar issue with my ThinkPad X230. The issue start with the most recent Lenovo wireless driver. I was able to find a new Intel Centrino driver for the wireless card. I installed it and the wireless problems cleared up immediately.

I suggest you see if a newer driver is available for your machine.

What make of Wireless card is it?

I have had some dell wireless antennas comes loose just enough to work for a the day and then the next day it doesn't work.  It is usually two wires that plug into the wireless card inside of the laptop.

I do not think that it is a problem.

My wild guess is that the DHCP server of your client has a short duration, say 24 hours, and your notebook will be assigned a new IP address when you connect wifi on another day.

But, is your notebook set to sleep or hibernate when you finish work on day 1 and you have not shut down the computer and on day 2, it just wakes from sleep or hibernation?

If yes, have a look of the link below.

It is a common practice if your client has many visitors and do not want wifi devices to reserve an internal IP address if the device is not in use as the range of the internal IP address might not be sufficient to entertain all guest and staff with wireless devices.

Run the following command in command prompt on day 1, day 2 before reboot, and day 2 after reboot.

  ipconfig /all

and post back the results.
