The (incorrect) behavior the other Answers describe would completely suck, because let’s say you live in the apartment above a Starbucks, and your AP is in the living room, but back in the bedroom, the Starbucks AP is stronger than your own AP. Most client implementations will stick on the current SSID, and only try to roam within APs of the current SSID, unless the client becomes completely disconnected from the current SSID. Most client implementations WILL NOT look at all “saved” SSIDs for roaming if they’re still attached to an AP for one SSID. I called this out in my answer to “How can I get the same SSID for multiple access points?”.īy the way, I need to point out that some other Answers to your question are spreading a false myth. Whenever a Mac or iOS device’s Wi-Fi interface says it has roamed from one AP to another, the network stack and DHCP client double-check that this is really the same network, in order to more quickly re-establish proper connectivity. Apple’s client devices (OS X and iOS) do something called DNAv4 (“Detecting Network Attachment in IPv4”: RFC 4436) to make sure this doesn’t happen to them. In a worst-case scenario that’s all too common, if both APs are acting as NAT gateways and using the same private IP subnet, a poorly-written client may not even realize it has switched networks, and may keep sending its Internet traffic to the MAC address of the old AP, not the new AP, until the ARP entry for the router times out. If the two APs actually connect to two different underlying IP subnets, this will break all the higher-level connections or traffic flows (SSH sessions, TCP downloads, video streams, mounted file servers, etc.) that the client had in progress.

So if you have two APs publishing the same SSID with the same security type and password (or no security at all), clients will roam to it thinking it’s part of the same underlying network. Wi-Fi clients can’t tell, before they connect, what wired network a given AP will connect them to. I would like to make two access points for two different wired networks look like one network, is this possible?Įveryone should obviously use a password on all WiFi networks always, this scenario was just to create the dead simplest example possible. I guess I wasn’t clear enough with my question. For example let’s say that John Doe has a network named Doe Internet, and Jane Doe who lives nearby has the same SSID, Doe Internet, and neither of them have a password protection, will wireless devices such as laptops and phones roam freely from one network to the other? Is there a way to configure access points on different wired networks to act as the same network?īonus question: does this pose security threats to people who could potentially enter onto a malicious network created by an attacker, using the same name as a nearby network? I was wondering if this applies to networks that are on different wired networks. Wireless clients just assume that all APs with the same SSID are configured similarly and are all just different points of access to the same underlying wired network. You can easily do so by clicking on the Time at the bottom-right and selecting the Gear icon.In reference to How can I get the same SSID for multiple access points?, particularly this line

How to find IP and mac address of a Chromebook from the Settings window In such a case, you will need to provide the network administrator with your Chromebook’s MAC address so that you can have network access. MAC filtering is a security technique applied on networks to prevent unauthorized connection. What is a MAC address?Ī MAC address (Media Access Control address) is a unique identifier assigned to the Network Interface Card of every device for communications within a network segment. That led to the introduction of IPV6 – a 128-bit address capable of supporting more devices. However, the growth of the internet, e.g., IoT (Internet of Devices), has led to the depletion of IPV4 addresses. There are two main IP address versions: the IPV4 (IP address Version 4) and IPV6 (IP address Version 6). An IP address (Internet Protocol address) is a numerical number assigned to every device connected to a network communicating using the Internet Protocol.
