Redo WiFi Setup
The goal is to have better wifi coverage as well as speed in all rooms of K20 and K22 as well as the garden. The basement is explicitly excluded, the street is a nice-to-have addon but can be filled later as well.
With the Wednesday mail, we get two TP-Link Archer C5 Access points. We already have a lot of ethernet cabling.
So our inventory then is:
- 2x TP-Link Archer C5 with 3x3 MIMO on 5 GHz (802.11ac) and 3x3 MIMO on 2,4 GHz (802.11n)
- 1x TP-Link WDR3600 with 2x2 MIMO on 5 GHz (802.11a) and 2x2 MIMO on 2,4 GHz (802.11n)
- 1x TP-Link WDR4300 with 3x3 MIMO on 5 GHz (802.11a) and 2x2 MIMO on 2,4 GHz (802.11n)
- (1x TP-Link WDR3600 seems to be missing?!)
- (a bunch of crappier 2,4 GHz only AccessPoints)
The goal, not reachable with this hardware, is to have 802.11ac coverage in all areas with at least -75 dBm signal strength (on a laptop) and at least -60 dBm in areas where there will be likely multiple people using the wifi with higher saturation. This leads to the following data rates:
- -75 dBm, 40 MHz: ~30 MBit/s per spatial stream as an absolute minimum so "bad" clients don't waste air-time
- -60 dBm, 80 MHz: ~260 MBit/s per spatial stream as a really good workable environment, even for bigger lan file transfers
The definition of done for this roadmap:
- One of the Archer C5 has been used to find out strategically important placements of the access points so the above conditions can be met
- A plan has been made to know the number of missing access points
- the first most relevant C5 access points have been positioned
- other access points are temporarily repositioned so a full coverage with 2.4 GHz, -80 dBm, is given
- A plan for switching most clients to 5 GHz is made (e.g. disable "wuppdays" on 2.4 GHz and use a "wuppdays_slow" SSID instead)
