thread_title:  OSI Data Link Layer mixed with TCP/IP one. 

message: Parts of this article are atrociously written, such as this non-stellar opening to the second paragraph: "The data link is all about getting information from one place to a selection of other close, local places."  The quality does not improve soon enough.
This is a poorly-worded jumble built on specious conceptions.  I will try to clarify and correct some of this.  --Talinus (talk) 00:30, 8 April 2009 (UTC)
thread_title:  Ghastly Second Paragraph 

message: "The Data Link Layer is concerned with local delivery of frames between devices on the same LAN."  This statement might suggest to a casual reader that the Data Link Layer" is specific to Local Area Networks.  That would be incorrect.  All networks (LAN, MAN, & WAN) make use of frames to deliver the network layer PDU between devices.  —Preceding unsigned comment added by 121.223.146.223 (talk) 14:22, 2 June 2009 (UTC)
thread_title:  Use of the Term LAN 

message: "The uppermost sublayer is Logical Link Control (LLC). This sublayer multiplexes protocols running atop the Data Link Layer, and optionally provides flow control, acknowledgment, and error recovery."  The use of the term "error recovery" in this statement might cause confusion between the concepts of error detection and error correction.  Layer 2 provides error detection or error notification, not error correction.  —Preceding unsigned comment added by 121.223.146.223 (talk) 14:30, 2 June 2009 (UTC)
thread_title:  Error detection and error correction 

message: "The Data Link Layer is often implemented in software as a "network card driver"."  This statement is incorrect and confusing. The driver can only implement the functionality of the hardware. It can never implement layer two functionality independently of the hardware.    The upper three layers (5, 6 and 7) of the OSI model are referred to as "Software Layers" because they are fully implemented in software.  The bottom four layers of the OSI model are referred to as "Hardware Layers" because they are heavily dependent on hardware devices.  —Preceding unsigned comment added by 121.223.146.223 (talk) 14:46, 2 June 2009 (UTC)

thread_title:  Plagiarised from ...? 

message: Section Media Access Control sublayer, second paragraph:
:If two people speak at the same time, they will back off and begin a long and elaborate game of saying "no, you first".
No, that's not Media Access Control. The explanation is outright stupid. The real explanation should be:
:If two people speak at the same time, they will pick up a 1000 sided die from their respective pocket, and throw it, observing the number that comes up. Then both of them will take up their stop watch and wait for that number of /seconds (or other time unit)/ and after that try to speak up again.

replies: text: Your 1000-sided die and stopwatch sounds elaborate to me.  Also, rolling the die and running the stopwatch has the intended effect of letting someone else go first most of the time... — Dgtsyb (talk) 09:20, 28 July 2011 (UTC)

message: A refimprove template was added to this page in 2013. Since then the article has gained five references. Some of the references contain plenty of information to support the information in the article although there are areas where the citation of these is not given. Nevertheless we don't have to cite for every sentence. All quotations and any controversial statements should be cited. So I wonder whether we have sufficient citations to remove the refimprove. I am going to boldly remove the refimprove now for the following reasons:
1. Article has gained 5 new citations supporting the material
2. The template is not working. After six and a half years we gained just five new refs. 
3. Removing the template may encourage editors to add "citation needed" to specific material they believe needs support, which could stimulate focused collation of sources.
