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 have a question about using several Wireless Access Points sharing SSID on the same location

I have a customer that is rapidly growing. They are expanding the area that needs coverage and are getting more people.

They started with a router with WAP (Wireless Access Point). This is an older router that is not Mesh aware. (Draytek 2820n)
They grew in size and added a dedicated WAP. We set it to have the same SSID & Pre Shared Key as the WAP in the router
Both were working well together and the users could roam around seamlessly

The dedicated WAP failed and we replaced by a new Mesh aware WAP (Cambium Networks cnPilot E400)
We also added a 2nd dedicated Mesh aware WAP (Cambium Networks cnPilot 1000)
We set these 2 Cambium WAPs to work in Mesh mode with the same SSID & Pre Shared Key

So they have 3 WAP
* the router's WAP  (non Meshed)
* WAP 1 Meshed with WAP 2
* WAP 2 Meshed with WAP 1
* all with the same SSID & Pre-Shared-Key

Since then the wireless users experienced constant drop outs and various instability. These are random and unpredictable

I am in the process of trying to debug the whole thing by disabling all WAPs except one then repeating the process with the other 2 WAPs

Question 1: do you see anything wrong with the set up as explained?
Question 2: Is there any reason to think that the mixed "Meshed" & "Non Meshed" AP would create this issue?
Question 3: Any other tests I could do?

Any other …

The IoT market is growing at a rapid pace and manufacturers are under pressure to quickly provide new products. Can you be sure that your devices do what they're supposed to do, while still being secure?

I'd like your recommendations on security cameras you may have CURRENTLY used. Nothing 7 years old please. ;) This will be a single camera system, not a DVR/mulitcam system.

We could use POE to power. Needs reliable (tested by you hopefully LOL) and easy to use SOFTWARE for offsite monitoring and time lapse (sent to FTP?). WiFi and tough, but cheap were also requirements.
I am getting terrible download/upload speeds on my MacBook Pro when connect via WiFi. See attached info on my connection. I'm supposed to be getting 50 down and 10 up from comcast, but with a wifi connection I only get 35 up and 3 down. When connected via ethernet I get the maximum speeds. My router is only 10 feet away from the laptop.

I have 2 routers (and a cable modem) in my setup. The modem goes directly to a Netgear Nighthawk R8000, and then extends the network to a Netgear Nighthawk R6700.
I have installed a Halo light fixture with two lights.  Both lights on are very bright and I would like to know if its possible to remove one of the lights.
How do I do it?  Please let me know.  Thank you
Hey Guys,

I have a UniFi Switch 8 150W, 2 UniFi AP AC LR and 1 UniFi AP AC Pro.  Do I leave the channels to Auto?  Also, do I assisgn static IP address to each or leave APs as DHCP?   By default does it use both bands 2.4 and 5 Ghz?   Thanks.
What sender do you recommend?
I have seen so many on Amazon and Ebay.

The distance is under 10m. The signal comes from a projector, output RCA, left and right.
I want to send that audio wireless to an audio amplifier which has Bluetooth receiver.
Most of the senders have a small battery incorporated, but I do not care, it can be also with power adapter. In fact those with battery have a kind of standby mode to avoid battery discharge. That is something that I do not really need.
One important request is this: when the analog signal comes (projector starts playing) I need that Bluetooth audio transmitter to send the signal right away. I do not want to go and press a button somewhere on transmitter. It should be like a self-activating, self-wake up mode, in case enters in standby. This is very important because that Bluetooth transmitter will be placed near the projector somewhere high and I cannot go every time there to activate manual the Bluetooth transmitter. I want to see this feature somewhere mentioned/explained before I buy it.
I am remodeling four homes.  I have  installed eight port structured wiring systems in all four.  Each wall jack (room) includes one ethernet jack, one cable jack, and one phone jack.  Everything is homerun to the utility room in the basement. Within the wiring cabinet located there, are punch down blocks and patch panels for all wires and cables. I would like to install  in each cabinet, an eight port router or switch to include an integrated DHCP server, and POE  jacks. One of these Jack's will be wired to a ceiling mounted Wi-Fi access point on the third floor in the center of the home. This device should be dual band AC 1200  or greater. Ultimately, the router or switch will be plugged into a cable modem providing Internet and telephone service. I am having trouble finding the router or switch, which needs to be small enough  to fit inside the wiring panel.  I also need an inexpensive access point device.  The cable modem will be mounted by the cable service provider outside the panel.  This arrangement will allow plug-and-play of any wired or wireless device in the home without the need for a PC  based DHCP server arrangement. Has anyone done this? Any recommendations? I need to keep this reasonably inexpensive.
Hello, I'm currently having issues with trying to update my computer to a newer Windows instalment. I was recently given an old-ish Windows XP computer by a family member and they completely wiped the computer and refreshed it back to its factory settings. Ever since I've received it, I've been trying to gain access to the internet so I can update its anti-virus as well as update it to more modern instalments of Microsoft Windows.

However every time I've tried connecting it, it says that the wireless wifi networks (that ARE in range) are apparently not or it has lost connection to them? Please help me, as I feel like I'm running in circles trying to find out how to fix it :(
I am looking for an outdoor security camera that can view an area remotely on a rural property. The area has excellent cell service on all major cell service providers, but no internet access. So I am looking for a single camera system that can be mounted on a light pole and stream video through a major cell provider like AT&T, Verizon, Sprint, & T-Mobile. This is my main requirement to answer this question.

Optionally, the camera would be able to:
  • Take time laps images
  • Move PTO and Zoom
  • Saves data for later use
  • Operate on solar power
If any of these features are included in the answer, it would be a better answer.

I realize that I can MacGyver a few systems together to make a solution, such as using a WIFI security camera with a WIFI LTE HotSpot device, but I am hoping to find an all-in-one solution that will reduce complexity and the chance of a disconnection/support.
i downloaded driver from tp-link site.but i don't know how to install it? tell me step by step. or another solution for driver installation.

I am not seeing a smoking gun on the WLC in the logs nor in radius (Cisco ACS). They're on the other side of the globe and communication is tough. What logging or troubleshooting can you recommend on the WLC/AP side. I've reviewed RADIUS logging and that looks largely normal - EAP MS-CHAP2/AD. There are a number of log messages concerning rogues. 200 or so rogues. But I don't think they'd be a problem. Cisco Clean Air b/g/b shows a worst case 91. a/n/c has avg 99 min 99 - and i think they're largely attaching via a/n/c.

I am unable to connect to my VPN URL  via anyconnect from my laptop using the house WiFi internet. The URL opens via the browser but using the application I face issues.

Error: No valid signatures.

The same works from the laptop when I connect it using my mobile 3g data via hotspot.
The issue seems to be with the WiFi.

The router is a TP link router.

Kindly suggest
1. How do I get my 1830 K9C WAPs (eBay purchase) ref-flashed to contain Mobility Express?

The kit says Mobility Express on it but my own configured SSIDs don't appear and I've discovered that the device has an http admin UI on some random IP address that shows something called OfficeExtend - so I'm think that the wrong software might be installed. I don't know what the correct thing should look like.

2. How do I definitively check that  Mobility Express is installed?

Someone said something about a “TAC case” - I don't know what that means but I'm guessing that I need a Cisco tech support contract, which I don't have, and nor do I have any idea how buy one or even whether doing so would be prohibitively expensive. To make things even more exciting, I am disabled and that limits what I can do myself to a great extent, so paying someone to do things for me is far more realistic than me doing a lot of physical stuff myself.
I have a bunch of Dell 7040 that are wireless throughout this facility.  These machines autologin and the users have no rights.  I can't explain it but some of these machines are having issues with the Network Card becoming disabled.  We checked all the power settings and they are set correctly, we have it not to save power.  In order to get the card enabled again we are having to login to command prompt with admin rights and use netsh commands to enable the card again. This is truly a mystery has anyone seen this before?

I have a client project where I am setting up this clients new office. He would like everything setup but scalable as he is growing and expanding quickly.

I have a lot of experience with the Dell SonicWALL's and I was thinking about recommending and quoting out the SonicWALL TZ 500 or 600 which has built in VPN and using the SonicPoints as wireless. I feel like this will be scalable as he expands to another suite in the building he is in and I can just add another switch and more sonic points. I also looked at the Barracuda 280 product which seems to be good except does not have wireless capabilities.

I just wanted to get some other opinions on what you would do or recommend so I can consider the best options for my client.

Thank you for your suggestions
Hi oracles.

Can you help me comparing 2 AP's?

One being UAP‑AC‑PRO from Ubiquiti.
Other being WAC6503D-S from Zyxel.

They really look alike each other, but the prices are very different and the management controller of the Ubiquiti system, seems more userfriendly but maybe also more limited.

They are both "Pro" models, with newest MIMO etc. etc. technologies. And made for pro deployment.
So im looking for a reason to pay way more for the Zyxel solution vs. the Ubiquiti solution.
Maybe a comparison, which im too stupid to find.

Looking forward to hear from you.

Best regards

I have bought a wireless headphone for my windows PC...I have installed all the necessary drivers...But still it shows Bluetooth Headset Disconnected in the Sound window...Any help is appreciated...

I recently purchased a few Cisco wireless access points (AIR-AP2802i-E-K9). Cisco provided me with a specific upgrade package I required (AIR-AP2800-K9-ME-8-3-112-0.zip) and I was able to upgrade two of my three access points but unfortunately one failed and is now in a unbootable state. From the console the AP start to boot, but then halts early in the boot process with:

BootROM: Image checksum verification FAILED.  

I am trying to find the recovery procedure or any form of workaround to get the AP into a bootable state. I have tried holding down the "mode" button during startup but no indicators lights are showing up. Does anyone know of a workaround to get the AP booting again? Can I perhaps boot from USB or physically remove remove the flash to try and reset it?

Thank you!
Looking to setup a wireless Point to Point network to 7 locations each location also has a basic isp.  The point to point will be running at 850mb the isp 20mb.  What is the best way to setup the isp as a backup line to the point to point? I just basically want it to keep my voip and basic data services afloat till the link is fixed.

My wireless router at home has failed.  A friend has offered me some kit his work have decommissioned but this is from an office, would it be suitable for home use.  It is an HP MSM430 Access Point.  I think it will need a PoE switch which isn't a problem, but I'm concerned it will be too powerful for home use?

Can anyone advise if it would be OK?

I'm trying to setup an SSID (vlan 30) in bridge mode, but whenever i change from NAT mode, it automatically changes back.

I'm using a Meraki MX-100 and 2x MR-18 AP's connected to Cisco switches

Vlan 30 is configured on the switches, trunk ports connect all devices & vlan 30 is allowed between AP's, MX-100 and Switches.

So setup looks like this

AP1 ---> Cisco-ASW1 --->Core-SW1--->Meraki-MX100--->Firewall(Internet)

Anyone know why I can't set the SSID to Bridge Mode?

hi all
i need complete information on icomera , what exacty the device is ? how exactly it work ? what technology it is using can i get complete information about ICOMERA
We are having problems in our WiFi connections in our school.  we have this GAJ-shield 20dc firewall. how can i check if how many user can support by this firewall...

The sale agent just told me that we need to change our firewall to support more user from 200 or more?

Can anyone help me. figure this out?
I am trying to setup a
Graphical user interface (GUI) for Google Compute Engine instance
as described here:

I got to the part about running netcat using
$ nc 5901

When I ran that (with my ip address) nothing happened. In the article it says it will fail. What happened to me was that it waited about 3 minutes and the the prompt returned silently.
I don't know if that counts as failing or not.
Then I added a new firewall rule

but the same behavior continues. Is this correct or not?
Thank you.
I'm setting up a CISCO WLC 4402 and testing connectivity with one LAP1142N-A-K9 access point.  The AP is discovered by the controller and picks up an IP address, but shortly thereafter it cycles through green, red, yellow and drops from the ALL AP screen.  After a minute or two, it turns solid green, joins the WLC again, and repeats the process.  This is the first time I've setup a WLC, so admittedly I'm struggling somewhat.  There are a ton of config options, many of which I've seen before.  I'm looking for a basic setup that I can explore and build upon.  Any help would be useful.
