Macbook Air 2012 Wifi getting slower

I have had this problem for some time. My Macbook Air (which was running perfectly for the first year or so) is getting increasingly slower on Wifi. I also have the problem that it has to signal reception in one of my rooms, with my other (even older) MacBook Pro having a full signal standing right next to it.

Change of Wifi Channels did not help, changes between 2.4 and 5GHz Band did nothing. This happens with one single application (Safari) running, regardless of DNS settings. I am running out of ideas.

Here is the system dump:

Problem description:

Internet is super slow and Wifi reception very weak compared to other Mac I own

Please answer as many of the following questions as you can. You may already have answered some of them; in that case, there's no need to repeat the answers.

Restart the router and the broadband device, if they're separate. Any change?
Are any other devices on the network, and if so, are they the same?
If you can connect to more than one network, are they all the same?
Are all network applications affected, or only some? If only some, which ones?
Is networking always the same, or is the problem intermittent?
Disconnect all other devices from the network. Any change?
If you're running a MacBook with the lid closed, open the lid. Any difference?
Start up in safe mode and test. Any difference?
Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?
If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

Restart the router and the broadband device, if they're separate. Any change?

Sometimes a restart of the router helps. But the problem is on every Wifi I attach to

Are any other devices on the network, and if so, are they the same?

The only device with problems is the Macbook Air

If you can connect to more than one network, are they all the same?

Yes, problem is the same

Are all network applications affected, or only some? If only some, which ones?

All applications affected. Speedtest shows slow speed and connection is poor with router less than 15 ft away

Is networking always the same, or is the problem intermittent?

It is worse at times, but never good.

Disconnect all other devices from the network. Any change?

No

If you're running a MacBook with the lid closed, open the lid. Any difference?

No

Start up in safe mode and test. Any difference?

No

Start up in Recovery mode. From the OS X Utilities screen, select Get Help Online. A clean copy of Safari will launch. No plugins, such as Flash, will be available. Any difference?

No. I even installed a plain copy of the OS and started all over.

If possible, turn off Bluetooth and disconnect any USB 3 devices. Any difference?

No

Make a "Genius" a ppointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.

Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

Keeping your confidential data secure during hardware repair

Apple also recommends that you deauthorize a device in the iTunes Store before having it serviced.

*An SSD doesn't need to be zeroed.
