I don't believe the statement "Hubs remain a very popular device for small networks because of their low cost" is accurate. Especially when this article also states that "The availability of low-priced network switches has largely rendered hubs obsolete but they are still seen in older installations and more specialized applications." Hubs are fairly obsolete and mostly used for specialized situations such as packet captures. I am considering deleting this sentence. Switches are cheap. —Preceding unsigned comment added by Daprofessor ( talk • contribs) 01:09, 13 February 2009 (UTC)
I renamed this from "Hub (computer)" to "Ethernet hub" since there are many different types of computer hubs completely unrelated to Ethernet hubs (e.g., USB hub, application hub, Token Ring hub). -- Rick Sidwell 23:13, 19 Jun 2005 (UTC)
I encountered the term "switching hub" but I was never sure what it means. It should probably be explained here, or does it require a separate article? aditsu 22:02, 22 February 2006 (UTC)
I have a question: Can you connect a dualspeed(10/100) ethernet hub to a singlespeed(10) hub?
I've never heard the term "Layer 1 switch" before in networking. It does show up (sparsly) in an internet search as a synonym for "Physical layer switch" but both appear to refer to a crossbar switch or relay bank, not specifically networking equipment. I've removed the reference.
"Concentrator" is usually used to describe a patch panel. Part of the cable plant, not the network gear described by this article. I've removed this as an alternate name for hub.
In my experience, hub is a sloppy term for this device. The term sometimes refers to network switches as in "switching hub" as discussed above. "Repeater hub" is more precise and preferred term for the device described by this article. —Preceding unsigned comment added by Kvng ( talk • contribs) 21:21, 11 August 2008 (UTC)
Yes, the term should be "repeater" or "repeater hub." Hub describes the topology, not the electrical function. As the first hubs were repeaters, the term tended to get used as it was shorter, but it is incorrect now that there are "switching hubs" (technically "bridging hubs" with more than two ports). Gah4 ( talk) 19:58, 11 September 2010 (UTC)
In the beginning of 10baseT there were only repeaters, and "hub" was a conveniently short form for the name. As it describes the topology, but not the function, it is also misleading. Repeating hub, or just repeater, is much better (but longer). I would vote for a separate hub page (or disambiguation page) with links to repeater (or repeater hub), and switch (or switching hub). (Even though technically a switch or switching hub is an ethernet bridge.) Gah4 ( talk) 01:28, 20 September 2010 (UTC)
Computer Networking WikiProject Support and Importance: This article was already supported by the Computer Networking WikiProject, marked with unknown importance, so I kept this article under the project's support, as it seems befitting, but marked it with top importance because ethernet hubs enable basic connections, the fundamental components of networks.
Class: I rated this article as a stub-class article because it has absolutely no sources. According to the WikiProject Computing assessment page ( http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Computing/Assessment#Grades), if an article has no listed sources, it is a stub, regardless how informative, well-written, or long it is. This is simply because such articles are not verifiable, which Wikipedia holds in very high regard.
Importance and Portal: The article falls under the description of low importance from the WikiProject Computing assessment page ( http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Computing/Assessment#Grades). The Computing WikiProject is concerned with fundamental components for computation, not networking connections. However, the article is not completely unrelated to the very general Computing WikiProject and falls under many subcategories of the Computing WikiProject (which is why I added this Computing WikiProject template and the computing portal).
Infobox: This article is technically lacking an infobox, so I noted that.
Computer Hardware task force WikiProject Support and Importance: An ethernet hub is obviously a piece of hardware, so I marked this article as falling under the Computer Hardware task force WikiProject. Since this piece of hardware is the sole object that allows for computer networks, I marked this article with High-importance under the Computer Hardware task force Wikiproject.
Computer science WikiProject Support and Importance: This article obviously falls under the general category of computer science since it is related to computers and allows computer networking. However, since ethernet hubs do not form the basis of any general concepts in computer science, this article seems to be of low importance with respect to this science.
WikiProject Websites Support and Importance: Since network sites can be accessed from ethernet hubs, it seems that this article relates to the Websites WikiProject. However, the relation is very indirect, since ethernet hubs, being hardware, are qualitatively different from websites and any of the components required for the creation of websites. Hence, I rated this article as being of low importance in this area. -- Some Old Man ( talk) 01:24, 21 May 2009 (UTC)

The article repeatedly talks about hubs forwarding network packets. However, packets are entities of layer 3 and don't exist from the very limited POV of a simple hub. A hub/repeater operates on the physical layer which consists solely of bits. One advantage of this is the reduced latency of hubs in contrast to switches. I'll try to incorporate that into the article. -- Zac67 ( talk) 22:28, 26 September 2009 (UTC)
Anyone up for giving this the proper name of "Ethernet Repeater" with a redirect from the common name of "Ethernet Hub".
Technically, hub describes the topology, not the function. The fact that repeaters were the first hubs does not make it correct. Gah4 ( talk) 21:45, 29 April 2011 (UTC)
Hmm. Originally they were hubs as the ethernet repeater was the only technology available. Considering WP:COMMONNAME, though, it seems that Reliable Source is an important part of the distinction. What is a Reliable Source in the case of Ethernet? Is it the standards documents, books written by writers of the standard, books by professional network engineers, or any old networking book? Gah4 ( talk) 09:03, 26 September 2011 (UTC)
There are (I still have one, though I haven't used it lately) LocalTalk repeater hubs. LocalTalk is the hardware layer for what was originally called AppleTalk, the network hardware built into many Apple Macintosh computers. I used to have a GatorStar which is a 24 port LocalTalk repeater attached to a LocalTalk to EtherTalk Router. Gah4 ( talk) 11:39, 6 January 2012 (UTC)
E. g. will it forward to ports where no network device is connected or where a network device is connected but not active ("Link" LED not lit)? 91.61.243.161 ( talk) 13:54, 10 August 2012 (UTC)
The grammar is atrocious..
"There are plenty of features of an Ethernet hub which the people need to be aware of. It is basically used in the LAN systems"
Either that or written by someone of which English is not their native language.

According to this article, the 5-4-3 rule applies to 10baseT. It does't. The 5-4-3 rule applies to coaxial (10base5 and 10base2) ethernet, along with FOIRLs. For 10baseT, you can have up to six segments of (about) maximum 150m length, as long as your transceiver cables (if you have them) aren't too long. (Normally you don't have transceiver cables, but the rules don't know that.) Gah4 ( talk) 02:32, 18 May 2015 (UTC)
Do they exist: (Soho-)Routers with builtin hub instead of a switch ? -- Itu ( talk) 01:35, 12 July 2015 (UTC)
This is utter nonsense. A repeater hub does not maintain a spanning tree anywhere. It does not work with any layer 2 information at all. Please stop editing this page and reread Spanning Tree Protocol, Network switch and OSI model. -- Zac67 ( talk) 17:24, 25 August 2016 (UTC)
There is no mention of using a hub for capturing packets? Modern devices like a tap or switch that supports monitor mode are relatively expensive or not available to consumers. Hubs are still an excellent low-cost solution for capturing packets on a small (LAN) network. Tmursch ( talk) 20:44, 4 May 2017 (UTC)
This article talks about the use of switches as having replaced shared access hubs but wireless uses air as the medium and thus shared access is still strong. Yes for wired networks switches have taken over. (I was redirected here from shared access.) I wanted to know if wireless routers repeat local link messages. 24.141.52.159 ( talk) 00:46, 11 October 2022 (UTC)
