Hi, thanks for taking your time to look at this. If you apply the text below for Denmark to db.txt, then it is an improvement: country DK: DFS-ETSI (2400 - 2483.5 @ 40), (20) (5150 - 5250 @ 80), (23), AUTO-BW (5250 - 5350 @ 80), (20), DFS, AUTO-BW (5470 - 5725 @ 160), (27), DFS # 60 GHz band channels 1-4 (ETSI EN 302 567) (57000 - 66000 @ 2160), (40), NO-OUTDOOR But I do think that Denmark has implemented "Short Range Devices (ETSI EN 300 440-1)". source: https://www.erodocdb.dk/docs/doc98/official/pdf/rec7003e.pdf (source is down at the moment, I have a copy of it on my work PC. I will send it on Monday) On 03-12-2017 17:51, Seth Forshee wrote: > On Tue, Oct 31, 2017 at 10:53:18PM +0100, Per Mejdal Rasmussen wrote: >> Hi >> >> I have taken the time research which frequencies and power levels are >> allowed for WiFi in Denmark.
