IN-USE BSSID SSID MODE CHAN RATE
I doubt that you selected channel 7 for your router as it is an overlapped channel. https://www.metageek.com/training/resources/why-channels-1-6-11/
I strongly suspect that your router is still set to factory defaults; however, many wireless drivers, including iwlwifi benefit from fixed, not autoselect settings.
WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP. Second, if your router is capable of N speeds, you may have better connectivity with a channel width of 20 MHz in the 2.4 GHz band instead of automatic 20/40 MHz, although it is likely to affect N speeds. I recommend a fixed channel, either 1, 6 or 11, rather than automatic channel selection. Also, be certain the router is not set to use N speeds only; auto B, G and N is preferred. After making these changes, reboot the router.
Next, I recommend that your regulatory domain be set explicitly. Check yours:
sudo iw reg get
If you get 00, that is a one-size-maybe-fits-all setting. Find yours here: http://en.wikipedia.org/wiki/ISO_3166-1_alpha-2 Then set it temporarily:
sudo iw reg set IS
Of course, substitute your country code if not Iceland. Set it permanently:
sudo nano /etc/default/crda
Change the last line to read:
REGDOMAIN=IS
Proofread carefully, save and close the text editor.
Moreover, you have a very modern wireless device that is easily capable of very high speeds that is connected to the oldest, slowest protocol; that is 2.4 gHz. I am certain that you will have much better luck connected, again with specific settings, to a 5 gHz router.
EDIT: I suggest that you connect to the 5 gHz segment of your router only. The autoselect feature of your router may steer you to the stronger, but slower 2.4 gHz segment but you can defeat that by renaming the segments, I suggest that you rename the access points; something like myrouter2.4 and myrouter5. Then, only connect to myrouter5.
Next, please check the settings in the router. WPA2-AES is preferred; not any WPA and WPA2 mixed mode and certainly not TKIP.
Also, select a channel that is away from those used by your nearby neighbors; check:
nmcli device wifi list
In my case, a few neighbors are on channels 36 and 44. I therefore chose channel 149.
After making any changes in the router, reboot it.
Is there any improvement?
