IBSS 54g Protection Mode. Although a weird name, this is an implementation of 802.11 RTS/CTS which is only enabled when an 802.11b node joins an ad hoc network; if you are sure there won't be such nodes you could disable this option, but given …

On Speedtest.net, on my 5GHz band, with 1 bar of service, I get a Ping of 9ms/Download speed of 9.77Mbps/Upload speed of 4.94 On my 2.4GHz band, with 2 bars of service, I get 9ms/35.19/0.70

2018年12月19日 · IBSS mode. Sometimes called "ad hoc" mode. This is a peer-to-peer (really multiple peers to multiple peers) Wi-Fi mode that doesn't require any device to act as the AP (wireless router). All the peers connected to the IBSS take turns transmitting beacons and responding to Probe Requests.

2024年12月7日 · Thnka @grawity. Yes, I don't want one of the RPi nits to become access point but get them to link using the IBSS mode. As mentioned, using the nmtui generates an authentication issue (question edited to clarify) –

2021年3月10日 · Of the two valid interface combinations listed in the iw list output, only the second one includes both "managed" and "AP" mode, and that one has a restriction that it can only use a single channel. In general, a single Wi-Fi module can only be on one channel at a time, but managed mode and those P2P (peer-to-peer) modes have mechanisms to let ...

2020年7月29日 · Looking at wpa_supplicant.conf I see that bssid is expected to work only for AP mode, but nothing is said about bssid_whitelist and bssid_blacklist. Using ap_scan=1 is not enough because when wpa_supplicant is started devices may be very distant (or the "bridge" device in the middle may be not running yet).

2016年10月19日 · Usually the role of the WPA2-PSK authenticator is played by hostapd on a device in AP mode. I'm not sure if any authenticator code exists in wpa_supplicant. Try getting Ad Hoc (IBSS) working with 40-bit WEP. Once you've got that working, research whether wpa_supplicant supports WPA2-PSK over IBSS, and how to set it up.

2019年2月26日 · IBSS mode does not provide a mechanism for one peer to forward traffic on behalf of another peer. So all IBSS peers that need to communicate with each other must be in direct radio range of each other. In your description, you described a classic "hidden node problem" where C is visible to B but hidden from A.

An IBSS (a.k.a. an "ad hoc" 802.11 network) has no AP. But the peers in an IBSS don't to Intra-BSS Relay, so you have the hidden node problem. In your example scenario, node A cannot talk to node C in an IBSS, because B is not an AP so it's not providing the Intra-BSS Relay service.
