If it is free, set a random time before sending data

Should that read :

If it is NOT free, set a random time before sending data?

Hello, I am writing in an unusual case … Some time ago, I used your services, and one of your employees face was familiar to me. At dinner with my wife, it turned out that he was a burglar, who 5 years ago broke into our home!!! This is ridiculous!!! How you can hire criminals? I found at least 3 bad entries for him at website for background check http://everifies.com !! I am sure there are more!!! Please do something about it, things like that are ridiculous!!!

Hi 9tut if you have practice material of WAN like your EIGRP it is very educative with packet tracer. I want to practice WLAN in packet tracer but i have no idea how to practice WLAN with packet tracer, if you have some material kindly update.

@jhon: They are in different frequencies. The device must get all necessary information about that AP, including frequency before “jumping” to another AP.

By: jhon

jhon — Sat, 19 Jan 2013 11:19:36 +0000

@9tut

Now,as i understand from your words

roaming : must have same ssid but both AP must be on different frequencies

so my question is if both AP were on different frequencies so how can roaming happen ?

and if we used different frequencies like 1,6,11 …..so there is no overlapping and there is no roaming ? so why different frequencies

thanks

Sorry I made one mistake on Q6. the second subnet range is from 172.25.32.0 to 172.25.63.255.

By: texray

texray — Mon, 27 Aug 2012 00:22:23 +0000

Q6. 172.25.0.0 given. No mask or prefix given. 172 is a class be address with a classful mask of 255.255.0.0 prefix /16. This is only one subnet with range of 172.25.0.0 to 172.25.255.255 /16. We want eight subnets. 2 to the number of host bits borrowed equals the number of subnets gained. So we want 8 subnets. Borrow 3 hosts bit because 2^3 host bits borrowed equals 8 subnets gained from one subnet given. So borrowing 3 hosts bits, we move our classful /16 boundary 3 places to the right which would give us a new /19 prefix. There are 8 subnets gained and we want to know only what the 3rd subnet is and we have a ip subnet zero command configured which means that the first subnet is 172.25.0.0 to 172.25.31.255. The next subnet is 172.25.32.0 to 172.25.32.255. the third subnet is 172.25.64.0 to 172.95.255. Look at the ip address choices in the question and choose those that fit into the third subnet’s range. I hope this helps.

Thank You

@CiscoMan: this further reduces the statistical probability of a collision. Silent -> random wait -> send

By: 9tut

9tut — Mon, 12 Mar 2012 11:03:28 +0000

@CiscoMan: It is not a mistake, if the environment is free, it still waits a random time before sending data.

By: CiscoMan

CiscoMan — Wed, 21 Dec 2011 09:26:10 +0000

Hi,

I think there is a mistake here :
+ Listen to ensure the media is free. If it is free, set a random time before sending data

It should be : if it is NOT free, set a random time before sending data.

Thank you for this great website.
