OK, you're using a Cable Modem that also acts as a wireless access point, it quite old and only supports 802.11G which is 2.4GHz, I think it may be time for a router upgrade....Netgear CGD24G. According to the router page:
Acquire Downstream Channel 585000000 Hz Locked
That is the only indication I could see........
The Surface Line of Tablets use the Marvell Wireless SoC which includes dual band (2.4 GHz and 5 GHz) 802.11N or AC (depending on Generation), Bluetooth 4.0 LE, NFC (not enabled) and FM Radio (not enabled) all on a single chip with an Antenna Array (On the SP3 the Antennas are located under the plastic cap at the top of device).I am considering replacing the Netgear CGD24G (provided by TWC) with the ARRIS / Motorola SURFboard SBG6580 DOCSIS 3.0 Cable Modem. Perhaps soon, perhaps later.
Just curious: What would/does the parameters of my router have to do with the number of BT connections my SP3 can have at the same time?
Nothing per se, but BT uses 2.4GHz so WiFi using that frequency can cause interference....
