Wireless Hardware





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.

Hello Experts,

I am at a client and checking the wireless controller, I noticed that this controller has list of access points some are local and other are flexconnect. The 3702APs that are local are showing using channels (64, 60)* and is controlled by global settings. The flex connect access points when I check on the 802.11a/n/ac are using single channel and the settings is from global settings. These are the same APs model 3702s , the site that has the APs configured as flex is having signal coverage issues but I want to know how to check the global settings on it and fix it so it uses more channels.

I need some guidance.
Thank you,

I am trying to make my Cisco 3600 series from lightweight to autonomous. So all I need to do is to tftp the new IOS to the AP. The tftp is working fine. The issue is I only have 10MB of free space on the AP and it needs 13MB for the new IOS. I have been deleting files on my AP. But not sure why I could not get to 13MB free of space. Any help will be greatly appreciated. Below is the message after the tftp.

Hello Folks

Just wondering what would you recommend for a wireless infrastructure. Let's suppose the physical survey is done and we're looking at 400 access points. Would experts recommend a cloud based solution like Cisco Meraki? Or should we get better performance/security from having on-site Cisco wireless access controller?

any suggestions would be highly appreciated.
i have an HP i7-by0055nr.   The Airplane Mode is off.   But the wireless will not stay turned on.   I ran updatesand the wireless stayed on for a couple hours then turns off and I can't get it to turn back on.   When I go into settings, I turn wireless on and before I get outof settings it is turned off again.   I ran anti mailware and nothing really came up.   Anu idea what is causing the wireless not to stay on?
Dear All,

       I would like to look for wireless AP which support POE without running controller, and it is using in School, any brand recommended ? any help would be appreciated, Thanks


We installed a HP Officejet Pro X476dw MFP for someone a bit over a year ago.

When we set it up and tested it, all worked as expected.

We have heard that this printer has not been working the last few weeks so I went to check this out for them.

When I went to power the printer on, it started up but an error message appeared on the touch screen: "There is a problem with the printer or ink system. Turn printer off, then on. If problem persists, contact HP".

There is no way of by passing this error and after trying power button, it says it is initializing something and not to turn off printer but no loading for initialising.

Inside the printer are 3 setup ink cartridges (coloured ones that came with printer) and 1 non-setup ink cartridge (black).

I tried the following to try and fix the printer:

1. Pressed and held power button to turn printer off - Printer did not power off.
2. Replaced non-setup ink cartridge (black) with setup ink cartridge (black) - Started initialising for 2 seconds then same error message as before
3. Took out all ink cartridges from printer then tried each one at a time - Started initialising for 2 seconds then same error message as before
4. Reset printer by plugging out power cord for 60 seconds then plugging back in printer and powering on - Powered on but same error message as before
5. Opened paper tray and closed while printer on - Noise was made by printer for few seconds then quiet

How do we fix this issue?

I just purchased this item and am not yet convinced that I should return it https://www.amazon.com/gp/product/B016K0896K/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

It's the right product, but I needed the smaller form factor.

It looks like that silver piece that holds it into the computer could be replaced with screws or I could return it and replace it with one that is a smaller form factor.

Assistance in finding either would be greatly appreciated.
Hey Brains Trust!

Has anyone seen this error happening on their AP's? A restart of the AP appears to fix the issue and it randomly moves around my AP's.

Each AP is a Radius Trusted Client as well as the controller. And is impacting a range of devices.
Hi, I'm looking for a WiFi mesh system that can use all hard wired nodes.  I also wanted one I could use a browser to configure.  I have used Asus IMesh, but each node communicates with each other via WiFi and it has caused me issues with distance.  I also used the unifi system, but the tablet app configuration method was wonky to me.

Thanks all.
I have Extreme controller..I need to read its running configuration.
sh run-config command output is like linix.

Is there any way to read it in cisco format?

Our customer has one room which has router in it and another room which has a PC and printer in it, but in this room the WiFi internet connection is not great.

To solve this issue, we installed AV2000 Gigabit Powerline ac Wi-Fi Kit TL-WPA9610 KIT in the room with PC and printer which has boosted internet connection and signal in that room.

We plugged in one PowerLine WiFi adapter near the router and WiFi extender in room beside printer and PC.

The WiFi was connected and two PowerLines paired.

We would like that if any problems happen where internet connection is lost and comes back, that these PowerLines reconnect themselves.

1. Will these PowerLine devices reconnect to WiFi if:
    - WiFi extender is relocated
    - Router loses WiFi connection and reconnects after few minutes
    - Both adapter or extender are plugged out and plugged back in after few minutes
    - Adapter is plugged out and plugged back in after few minutes

2. We have heard that one day, a few people tried to connect to internet where WiFi extender was but internet connection was lost. The next day we reconnected fine to the internet. What could be the reason for this?

got dws 3160- dlink wireless controller.
it is something a new device which i came across. all dlink access points are managed from this controller.

i found all access points are 2 or 3 firmwares behind. i want to update firmwares in all access points.
is it something anyone knows here how to update firmwares for access points from dws3160 controller?  ??   i can see the access points ip address from controller, but cannot get to web page of access points with ip address . think that is how it works.

so any ideas or steps to upgrade firmwares in access points through dws3160 ? ?
i checked for youtube videos, could not find any video
My home has Verizon Fios connection with the FIOS G1100 wifi router. I tried to block some websites from my kids and found it is not very effective. Can you recommend some please?

Your input shall be highly appreciated.

We have a Motorola security camera that we are trying to setup and connect to our WiFi.

This device needs WiFi but when we go to connect it to our WiFi, the camera does not pick our WiFi up.

The supplier has said that the camera can't connect to WiFI if it is not secure (has no password).

We do not wish to secure our WiFi at this moment as doing so would effect all devices connected to it and take time to connect with secure passwords.

Is there anything we could put between our WiFi and our camera as it needs secure WiFi.

Within a public school that is using Aruba AP-105 access points that are about six/seven years old, a one to one environment of 300 Windows laptops is setup for student use.  Presently, I am trying to reimage these laptops with an updated Windows 10 version 1903.  For some reason, the laptops for reimaging which are connecting wirelessly will disconnect from the Internet, lose DNS connectivity and ping response temporarily stops then goes back on at random along with Internet connectivity and DNS connectivity.  Are there any tools that might give us a bearing on what is happening?  Problem seems to be with wireless access points and not with ethernet and it still persists even when additional access points are added.   Can the problem be with some sort of network attack to the firewall appliance?   In this case it is a Smoothwall.

I am trying to help our local parish with their IT equipment.

They have a Windows 10 Pro laptop in one room beside where their router is located, an empty room beside that and a room beside the empty room which has a Windows 10 Pro PC and HP Multifunction printer in it.

All devices are connected to the internet wirelessly through the one router.

As the walls are quite thick, the PC and printer have a harder time connecting wirelessly to the router.

What would be the best device to put in the middle of these devices to connect them better wirelessly over the internet.

In a business that is spread over three buildings, I am trying to connect Unify NanoStations to extend wireless access from the first building in which the ISP comes into.  From the ISP's router, I have an unmanaged switch connecting to a Nano mounted on the outside of the building where the ISP comes into.  From there I have it pointed to a second Nano mounted on the second building through another unmanaged switch and a Unify AP is also connected to that same switch within the second building.  Internet is working fine in the second building.  A third Nano is mounted on the second building with another unamanged switch connected to it.  The fourth Nano is mounted on building 3 with a fourth unmanaged switch and a Unify AP connected to it.  Initially, building 3 connected fine and also connected without the third Nano's help for a short period of time.  Recently and presently, I get a blinking light on the AP and no Internet connectivity.  All devices are setup to talk on a 192.168.2.x network.

Any suggestions?
Trying to use Trendnet Wireless Bridge with an Aruba IAP-205-US as the AP.

I have a small office in a warehouse that we want to run a few desktops off of using  Trendnet TEW-740APBO connecting to a ceiling mounted Aruba IAP-205-US.

The Trendnet connects and If I assign a static IP to the devices, it passes traffic, but DHCP does not work.

I can't find anything in either side Trendnet or Aruba that should block or allow this.

Using the Cisco WLC, how do you adjust the noise floor from near by waps that a Cisco WAP could hear?
Cisco Wireless help for a customer.  They are install a new nurse call that identifies location and using their Wireless infrastructure that is dated.  I am guessing the direction is going to change when they find out what the cost is to add what is needed, but I need help identifying the correct hardware needed to get pricing.  
Current Environment
50 - 1142N Access Points
2 - 5508 WLC
We are being told that they will need the following:
Cisco Prime Appliance that is compatible with controller.  Not sure what how the licensing works, so need help with that.
They also need CMX or MSE as well and they really don't have anything to run this virtual.
Can someone point in the right direction on what the correct appliances are to get pricing and licensing needed?
Hi All,

I'm having a heck of a time trying to get my Bluetooth headphones to connect to my desktop PC and was hoping somewhere here can offer some insight on what I need to do.

I have a desktop running Windows 7 Pro, which supports BT connections (I also have a wireless keyboard/mouse connected vie BT.

The headphones in question are AudioMX-HB-8B. The weird part is that they actually worked in the past, but ever since I rebuilt my computer, I haven't been able to get them working, and I remember I had difficulties setting them up originally, but eventually I did the right combination of steps to get them working.

When I go through the pairing process, my computer finds it, and says it's all set up properly, as indicated below:

However, I don't see it in the Device Manager:

Or in the Playback Devices list:

This leads me to think it may be a driver issue, but I can't seem to find a specific driver for the make/model. I've tried disabling all other BT devices, same thing. I've connected it to my phone with no problems (I always disconnect and "forget" the device on my phone to avoid any conflicts. I've even tried with another generic USB receiver, same thing.

Any ideas/suggestions would be most appreciated :)

Hi Experts,

I was wondering if someone could guide me on configuring Cisco WLC 5508 as High Availability? My client has an existing 5508 WLC, and now purchased another 5508 as HA SKU and would like to set up the new 5508 as HA. Both WLCs are in the same location (same rack even). I read some guides online but maybe someone has done it recently or has concise instructions on the best way of doing this.

All tips and comments are appreciated!

Thank You!
Since last year, we have been using Ubiquiti radios to connect for internet connectivity from one point of our new office to the other.

However, now we are considering to use point to point, directional antenna WiFi transmitters. Kindly recommend the radio to use for video feed of 4k of up to 16 camera https://www.amazon.com/dp/B01N0B6KSA/ref=cm_sw_r_wa_api_ysh-BbDAEKWAS   from same distance.

I recently got the recommendation for Cambium Force 300. Is this advisable or something else ?
