Wireless networking is a method by which homes, telecommunications networks and enterprise (business) installations avoid the costly process of introducing cables into a building, or as a connection between various equipment locations. Wireless telecommunications networks are generally implemented and administered using radio communication. This implementation takes place at the physical level (layer) of the OSI model network structure. The key hardware components of a wireless computer network include adapters, routers and access points, antennas and repeaters.

We are moving into a 12,700 Sq foot new location.  See attached floor plan.  There is no budget for a full on centrally managed wireless network.   What is the best way to get full wireless coverage in this space for about 30 users and the odd guest that comes into the office?  I need to have access in all corners of this space.

P2P Autonomous Mode Wireless Bridge

Hello,

I have done a mesh deployment wireless bridge before where the RAP connects to a switch thus connecting to the WLC. The MAP connected wirelessly to RAP and thus connected to WLC also.

This time around, the client requested a P2P Wireless bridge between two buildings using 2 Cisco 1532e APs. So far so good. However, the kicker is that neither side has a switch for the AP to connect to because he doesn't think a switch is needed. He kind of expects the two APs to magicaly work together. Now, he did say that he just needs those APs for P2P bridging, not necessairly for clients to connect to the bridge. I think that we need a switch connected to their existing network at least on the RAP side, no?

Could those 2 APs form a wireless bridge without a connecting to a switch?

Using Microsoft Call Quality Dashboard I stumbled on the fact that call quality for people using 802.11ac wifi is 4x better than for someone on 802.11n radio.
What could account for such a dramatic difference?

For one month 802.11ac: 978 good calls and 8 poor - .81% poor.
For 802.11n: 390 good calls and 14 poor - 3.47% poor.

Any thought as to how radio type would affect call quality to that degree?

Looking at any WiFi controller Aruba Cisco etc

Requirement is for guest WiFi users to be set to a password that doesn’t change

Are there guest access ways of doing this on controllers so that users have no access to the main network

I was looking at static IPs or even a separate scope with 10 addresses (required for 5-10 VIPs) what’s best way to do this? (In general with modern WiFi controllers examples and 2012 Domain controller setup)

What is the difference between the Cisco Aironet AIR-CAP3602I-E-K9 Access Point   and the CAP3602I-A-K9 Access point.

The difference being the E vs the A.

Is it possible to convert a A to a E? or vice versa. Thank you.

I do have internet connection from ISP, all my phone, computers etc. can get internet access from the wireless router provided by ISP, however, I am thinking about building a standalone, segregated wireless network for my security camera system by adding another wireless router to do this job, under this setup,  a POE switch will be plugged into this wireless router, and all the cameras will be connected to this switch.  After having tried the old apple airport extreme wireless router without the internet, it does not function at all without the internet connection, one of the LED keep flashing orange color instead of green color.  My question is: are routers like this that have to work with internet connection? if not, any router model recommended to fit my purpose(work without internet connection)?

Routing problem.... I do not think so.  What do you think?

I am trying to setup a new Wireless setup.  We are currently using HP MSM760; but, it is E.O.L. and we purchased an Aruba Wireless system to replace it.  I have never worked with either Wireless Systems and I am charged with:


1.  Learning how the HP System currently works.

2.  Duplicating the setup in the Aruba system.


I have been reading Aruba user guides  and setup you tube videos and I have everything connected and I have begun testing the SSID's.  The problem is that when I get any laptops or wireless devices connected they get authenticated and the device receives and IP address from the correct VLAN.  The Device shows up in the DHCP server and the IP address is associated with the Computer name; but, those wireless devices cannot ping anything on the network nor can anything on the network ping them.

I think that there must be a configuration setting that needs to be enabled.  Something that is unique to Aruba and outside the instructions I was given.  Aruba Support is stating that this is a network routing issue and they cannot help unless the main router can communicate with the wireless device.  I personally think that the reason there is a routing issue is because the Wireless Client is getting Authenticated into the Aruba system and a configuration setting is required to allow routing.

The thing is that the Aruba controllers can ping  devices that are on all of the required VLans.  The…

Hello and Good Evening Everyone,

              I am attempting to set up a Lumiman Smart light bulb which will require the PlusMinus app.  That said, could someone provide a direct download link for the PlusMinus app?   From what I gather, it can be obtained  from Google Play or the Apple App Store.  But, I am not sure though.

              Any feedback given in reply to this question will be greatly appreciated.

              Thank you

A very strange thing happened and wanted EE advice.  We have android phones and a iphone phones.   We are setting up some computers and its wifi router in an office.  In order to detect the best signal possible, we used an apps that would detect a wifis' router signal connection and see speed or fluctuation, etc. so we can discover the perfect spot for all devices.

For some reason the android phone had better reach to a wifi router and the iphone super less.  For example, the apps would display 121 mbps and the android phone and in the iphone would detect 23 or 50 mbps - placing both phones next to each other, inches away the wifi.  

Please advice on possible cause.

Thank you in advance.

Hello and Good Afternoon Everyone,

           I am attempting to set up a Lumiman wireless bulb with my Amazon Alexa which is leading to some questions.  As part of the setup instructions for Alexa, I am being required to input my "Plusminus" account and password.  I am not sure where to obtain these credentials because this information was not provided up receipt of my wireless light bulb purchase.  That said, could someone provide the needed steps for obtaining this information?

           Thank you

Hello and Good Evening Everyone,

         As an extension to a previously closed post, I am wondering where I can go online to purchase a wireless light bulb which will be compatible with my Amazon Alexa (2nd generation) and supported by any of the integrated skills within the Amazon website app located at https://alexa.amazon.com.   The bulb will need to be dimmable and multi-color manipulated through simple voice commands given to Amazon Alexa (2nd generation) and not require a hub.  

          Any shared online link or links to this Smart Light Bulb of interest will be greatly appreciated.  

          Thanks so much in advance for any feedback given to this question.

Cisco Mobility Express - I have 2 - 2802E's and a load of 2702's
One I have setup as a controller works fine, now I want to setup the second 2802 as a failover controller.

Initially I flashed it with the lightweight firmware it joined then went into my ME controller and said convert to ME, now it comes up ME capable.
That one seems to sit on the setup wizard at least when I look at the console port.

The first time I gave it some time thinking it would get the config and eventually just come up as a controller but nothing.
It does show up in ME as ME capable. I went into my controller and clicked make ME Controller it just rebooted and went to the same place.
I ended up rebooting it there essentially killing the setup wizard. It seemed to work but the secondary controller kept disappearing in ME until I rebooted and then it would show up again for a while.

I reset it and flashed it as a CWAP again, worked fine.
I had ME convert it again and this time went through the wizard and gave it the same settings as my main controller, it came up and I click Make ME controller now they are fighting back any forth I'm guessing over the management IP which makes sense so I just shutdown the second one for now.

I can't find a single document regarding bringing up a secondary controller using on premise ME unit.
I found documentation using cloud based services and using full blown WLC's but nothing in regards to what I'm using.

I found a few brief mentions about …

Cisco 2802 CWAP will not join 2802 Cisco ME Controller.

Pardon me I'm not Cisco expert but we've been running 2702E's in Autonomous mode successfully for a few years so obviously ME is a step up.

I have a 2802 online and I keep ending up with "Max retransmission count exceeded, going back to DISCOVER mode." when it tries to Join the controller.
This is first AP I'm trying to join and I don't have another one to test with right now. I need this one online so I can pull another offline and get it online.
Devices are on the same LAN and even switch for testing.

I changed the retransmit count and interval on the ME controller shown here:
(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
TX-2802-1                5                8


However this is what I end up with when the CWAP tries to join:

(Cisco Controller) >show ap retransmit all

Global control packet retransmit interval: 5

Global control packet retransmit count: 8

AP Name             Retransmit Interval  Retransmit count
------------------  -------------------  -------------------
MX-2802-1                5                8
AP00A3.8E90.F1DA         3 (default)      5 (WLC default),5 (AP default)
(The second one obviously being the one I want  to join)

I have an issue where a HP ProBook 4540s cant see the wireless network. It picks up other nearby networks and all other devices can see the wireless network and connect. The network is not hidden and the laptop has the most up to date drivers. The laptop used to see and connect to the wireless network and nothing has changed in the setup.

Some friends are purchasing a portable auction system running on a few laptops. This system is being purchased from scratch, so the technology on the laptops and networking hardware is open for debate as well.

Since the system will be portable and each auction location will have different "levels of local WiFi interference", I want a cost-effective wireless system which will "blow a hole in the atmosphere" wherever they will be for each auction. Coverage shouldn't need to be more than 3-4 acres (max) but a single auction may have a house, barn and steel building which would need coverage on the inside as items are being sold.

As a result, I'm wondering:
  • Are there technologies we should focus on (or stay away from)?
  • Is there hardware we should focus on (or stay away from)?
  • Are there brand(s) we should consider (or stay away from)?
  • Are there antenna(s) we should invest in (I realize this may dictate brand(s))?

I would rather not use WiFi boosters / amplifiers but they may occasionally be in basements, barns, steel buildings, etcetera. I would also rather keep it as open as possible (i.e. interchangeable antennas as needs arise (if special antennas end up being part of the solution). I've had experience with Cisco, Ruckus and your standard everyday brands like Linksys, NetGear, etcetera but am brand agnostic, as long as it is cost-effective, reliable and the coverage is what it needs to be. In the …

As we know, AP needs to get ip address first when it wants join WLC. so its dhcp server is very important. My question is if the AP is assigned with static ip address, do you think the dhcp server is still very important? I mean if the AP needs other function from the dhcp server? thank you

I am looking at getting a new Wifi solution for our new building.  I have looked at Meraki, Ruckus and Arruba, Sophos and even at a Cisco controller option.
I'm having a hard time deciding which solution is best for my environment.  We have two separate buildings, but will all be one system.  Hands down, the Meraki cloud has the best analystics and displays the data the best, my opinion, but it's not the cheapest.  Going from a controller based to cloud based design makes me uneasy, as if the internet goes down, then my entire wifi is down as well.  
By far I like the Meraki dashboard and the options available in their cloud.

We will need about 50 APs for both buildings.  I'm working with a vendor that said after we move forward with the purchase, they will perform a heatmap analysis, so we know where to place them, so that's good.

Any suggestions what to look out for, or any recommendations?  
Does anyone not like Meraki or any of the others I mentioned?

I have 3 Netgear Nighthawk routers set up as my network. The main router is connected to a cable modem. The other two routers are configured to be access points. They receive their connection to the network via ethernet (on the WAN port). Each router's wireless settings are configured to be on a different channel to cut down on interference issues. Each router has the same SSID.

I've noticed that my speed generally suffers with this setup. However, if I change each router name to a different SSID, it seems almost twice as fast when I connect to one of the routers when they have unique names. I've tried this with multiple devices and across different parts of the house.


What could be causing this?
