![]() ![]() You may also have a setting on your APs for wireless transmission signal strength - this is another method for reducing overlap between APs, potentially forcing OS X to switch to a stronger signal sooner. Options that you may have, depending on your wi-fi hardware, include setting your APs to strict 5GHz-only mode (if they are dual-band devices) - this will reduce the transmission range and therefore reduce overlap between APs. What you can do though is alter your wireless environment in an attempt to force OS X to switch between APs. So, there you go, there's not a lot you can do to alter OS X's roaming behaviour. However, our experience on campus with OS X clients shows OS X to be anything but aggressive, insead preferring to "stick" to an AP it has associated with in spite of being in range of closer/stronger signals - like your situation. ![]() This document from NYU suggests OS X has "aggressive" roaming characteristics and shows the command line to disable aggressive roaming. Windows gives easy access to this parameter, example here, but no simple option exists in OS X. This parameter dictates the point at which an OS will switch to a stronger signal. Your issue is being caused by OS X's handling of a wi-fi parameter commonly referred to as roaming threshold. I'm not sure whether that suggestion only applies to Airport products (given the name of the command). ![]() Do I need to ensure that all properties are identical between the access points? eg Channel, Width and Mode are different - does that matter?Įdit: as per an answer at I changed: sudo /System/Library/PrivateFrameworks/amework/Versions/A/Resources/airport prefs joinMode=Strongestīut this has no effect when moving between rooms.Is there anything I need to do in Mavericks to select the strongest network automatically?.(I left the laptop on overnight and it hadn't changed after 12 hours, so it's not related to timing) While located near the TP-Link powerline adaptor, I connect to the network, as shown by the bolded first line in the Wifi Explorer window (this is the expected behaviour as that is the strongest network):īut when moving closer to the Netgear wifi router, Yosemite doesn't disconnect from the TP-Link access point and connect to the Netgear access point (even though that network is much stronger): Unfortunately, OSX Mavericks isn't automatically switching between the networks when moving around the house. So I set identical SSID, security and password on both wifi APs. A client will scan all channels looking for APs publishing the SSID it wants, and will pick whichever one suits its needs best (usually that means whichever one shows the highest signal strength). Give both APs the same SSID, security type and wireless security The advice at How can I get the same SSID for multiple access points? is to set the same SSID on both wifi APs, and the laptop should automatically pick the one with the strongest signal: Previously I had separate SSIDs for each of the wireless access points, which meant that I needed to manually change the wifi network when moving around the house. I'm using a 2014 MacBook Pro with Yosemite 10.10.1 I have a Netgear wireless router in one room, and a TP-Link powerline adaptor with wifi in another room.
