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.

A client has Comporium WIFI internet service package. They have 1 static WAN IP, subnet and gateway.
From this, they get 10 usable Static LAN IP's to be populated in 9 other separate WIFI routers. The main router gets the static WAN IP as it's static info, and an address pool must be created that is the range of the usable LAN IP's, for example, - in this main router. This is used in place of the standard - found in most routers. The client purchased 12 TPLink C1200 Wireless Routers, but these units will not allow the change in address pool to a LAN static IP range.

So we have the main router that has to have a static WAN IP. The address pool is setup with the range of usable static LAN IP's and then each of the other routers get setup with one of the usable static IP's. They want 10 routers in all. It seems they need a business WiFi router instead of a home based unit. Would prefer all 10 to be the same brand/model? Maybe just the 1 that has the odd settings for the address pool to be business class, and leave the other remaining 9 in place? They are all currently mounted on a wall.

Any suggestions on a router that can have a static WAN and then the address pool set to static LAN IP range?
Trying to project my Wifi signal to reach 700ft with a beamforming signal to reach my property across the road from me. I was thinking of using a Wireless N600mW smart router R10000 from walmart. Would this be adequate or would this require a directional antenna to broadcast the signal?

It seems that some of the CLI commands have changed from the 3700 series to 3800 series Cisco access points.  Can someone help me with the follow:

3700 Series:
To change the IP address: capwap ap ip address
To change the gateway: capwap ap ip default-gateway
To change the primary controller: capwap ap controller ip address

3800 Series:
Any idea how to fix this error?
I setup wifi in a 4 bed 2 storey house & there have been alot of wifi issues!
Multiple devices & 4 heavy users.
Apple Tvs, Ipads, Macbook, Iphones & 2 windows laptops
Constant drops on wifi & constant reboots of Fiber router.
EG Freezes when watching netflix & need to connect to another SSID.
They get approx 50mb download from the router (which also has wireless enabled)
They didn’t want to wire so i used 4 tplink powerline av600’s
(i’ve used them before with little issues)


So i’m thinking of just swapping out the AV600’s with Archer C2 wifi routers & using standard tplink powerline plugs


I setup as Access Points.
I disable dhcp, wan, use separate channels, disable firewall,nat,guest network. I set dns to &
All have seperate SSID's. A mix of 2.4 & 5G.
I set the 2.4 channel width to 20mhz
I’ve been testing on my home network & it works fine then just loses connection for a couple of mins.
Happens every hour or so.
I get obscure DHCP error messages in the system log.
I upgraded the firmware & it’s more stable but not perfect.
I try continuous pings from a pc & ipad & they seem fine?

Other than hard wiring is there any advise to minimise issues?
Or is it a limitation of powerline?
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 …
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.

You might have a modern environment with all sorts of high-tech equipment, but what makes it worthwhile is how you seamlessly bring together the presentation with audio, video and lighting. The ATEN Control System provides integrated control and system automation.

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 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?

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?
