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.

Have a building that needs internet access and the the people that were inside said that using their smartphones would be fine.  Here is the problem:  The building is steel and they cannot get cell service AT ALL.  So of course no internet with phones.  Is there a solution to this by placing an antenna or something outside of the building and running a cable to a wireless router inside that the phones can hook up to WIFI?  Or is there a better solution for this scenario?  I was hoping not to have to pull in an internet line that is not there at the moment.

Hi All,

I am using 6 Sonos speakers in multiple rooms at the same floor.
There are 2 accespoints with the same channel and same SSID .

When one accespoints is online the most 2 far removed speakers stutter sometimes or loses connection, the other speakers wont stutter or lose connection when this happends.

If I connect both accespoints then only 1 or 2 speakers keep working while it has the same configuration as the other accespoint.

I tried several things like changing the channels or disable mesh encryption but Sonos keeps failing.

I searched online for multiple options but it seems a lot of people have issues with the Sonos speakers with multiple accespoints in the same configuration.

Does anyone here know a solution so i can use all my Sonos speakers at once over 2 accespoints?

Kind Regards,

Hi everyone

I want to backup the config for a Cisco Wlan Controller 2100 & 4100 models, I believe it can be backed up directly from the GUI of the WLC ? I'd like to do it directly from a Windows server. Do I need to install TFTP software or can the config just be downloaded to a folder on the Windows Server ?

Thanks all

Hello People,

This is kinda engineering question. Its about the hardware and power knowledge.

I have a Ubiquiti Loco M5 which is connected to a public access point (No encryption required)
Everything is working, except random disconnection which I'm pretty sure its because of the range. Its connected with -80
I am 1 Km away from the AP - but the signal is poor because Loco doesnt have enough power!!

How can I boost the receiving on Loco M5. I mean HARDWARE. not configuration within the Loco which I tried EVERYTHING.

I need something to add to the device in order to make it more powerful for receiving signal! like changing the adaptor? or PoE? I've heard if I changed the power supply, it'll help. But I have no idea about the power and what should I buy.

Any ideas?

I have a refurbished AIR-AP1852I-B-K9 that I am trying to join to a 2500 WLC. This is number 2 of the 2   we ordered. The first one joined on its own no problem without any intervention from me, this one is being stubborn.

I keep seeing this message:

[*12/18/2017 12:50:19.8397] Discovery Request sent to X.X.X.X, discovery type STATIC_CONFIG(1)
[*12/18/2017 12:50:19.8497] Discovery Request sent to, discovery type UNKNOWN(0)

I set the first IP (capwap ap primary-base <wlc name> <wlc ip>) but do not know where the other one came from. I see the clock is off and am not sure if that is contributing to the issue or not.

I have tried just about everything I can think of including multiple factory resets, statically assigning an IP and updating code. (which failed) I am now am out of ideas unfortunately.

I can see the AP as a CDP neighbor on my switch so we make it that far. It also pulls a DHCP address. We do not use option 43 so pointing the AP to the WLC should work.The CLI is limited on these compared to what I am used to working with also.

Any ideas?
I'm trying to use a Draytek Vigor 2760Vn to extend a network using WDS. I am trying to use the Draytek router as a AP to extend the current network without having to use extra cables. The network using a BTHub 6 for its main wirless network. The Draytek router is in another room that will have some computers connected the the physical ethernet portds.
BTHub 6 - IP addresss, DHCP range -
DrayTek - IP Address using the same SSID as the BTHub

When I configure the DrayTek using the WDS configuration, I scan for the BTHub SSID. Under the AP Discovery, It is found and I click the BTHub SSID selct the Add To button and select it as a bridge.
My goal is to keep all devices on the same network and use the Draytek to replace a VOIP router.
What am I doing wrong?
i had question req Cisco air cap 3602i. can i use this as standalone access point .or is that mandatory i should connect trough Wireless controller . if yes  i have tried connected with the
connecting but in putty its not showing anything..totally blank screen .am using POE adapter. i have connected console cable to my system with usb converter .and another patch cable to the AP port on power adapter. hope  this the right way..and in device manager it is showing com 4 . and i have changed to com 4 in putty..but still its showing their anything i have to do. and any other way i can config.. please suggest
What is  mouse-over control?

Compaq presario cq57 wireless/f12 button stays Amber and will not connect to wifi. The laptop was shutdown improperly by pushing and holding the power button. I had to reinstall Windows 7 just to get the rest of the laptop to work. Please help
Installed a new SonicWall SOHO wireless router and the other computers at home cannot be viewed over the network.

How do I change this?
home network devices not finding new SonicWall SOHO Wireless.  It also is not being detected on my phone.
I am trying to understand why I don't see the actual configuration when I access the AP via the GUI. in CLI, I can see Radius, TACACS, and other good stuffs. But on the GUI, all I see is the IP address of bvi1. Thanks
I’ve purchased a total of 3 roku streaming sticks. The first one was defective and returned it to Amazon. The second  one was defective and I also returned it. The third one I went to Best Buy and made sure that they were able to pair the remote with one of their TVs. It was able to pair at the store. However, when I get home the remote control won’t pair.

So this is the same problem with all three streaming sticks. I cannot get the remote control to pair with the stick. I have done all the troubleshooting over the phone with Roku. We have done all the resets imaginable. It’s odd that it worked just fine at the store. I bought the very same Roku that they were able to pair and brought it to my house. When I get it here it’s asking me to pair it and the pair is unsuccessful.

Very frustrating. I don’t need any of the normal advice for how to pair and troubleshoot this device. Everything has been done that could possibly be done with regards to Roku support on the phone. And the fact that it works perfectly fine at the store.

Could there be something in my house such as conflict with some other remote controls that is impeding this? Any ideas that I haven’t thought of?
There years ago I bought one of these for $30

I would like to buy another put the price is outrageous. Like $300. There’s something wrong with that price. I don’t care if it is exactly the same or not. I just need something to accomplish this: I need to take the WiFi that is in the radio waves Around me and convert that into a stable Ethernet port. Short and simple.

What product would you recommend please ?

I am responsible for recording training sessions and I need a way to obtain an improved recording of both the presenter as well as participants questions.

I believe the best option is to find a unit that includes:
- 1 lavalier microphone - wireless (for presenter)
- 1 desk microphone - wireless for participant
- 1 microphone mixer/receiver (two channels is all that I require) - must have an output jack with proper impedance to feed into a MacBook Pro audio recording the two channels.

Another option: bluetooth mics with Mac OS software audio mixing.

I don't have much of a budget so ideally, I am looking for a unit that is under $350.

- Most of the models that I have looked at are either more than $350 or are packaged with the wrong types of microphones (i.e. handheld mics or 2 lavalier mics).

Thank you for your advice. :)
I have a new Samsung WEA302i. I want to configure it as a standalone access point which i understand is possible.

When I browse to the IP address of the device I just get a "Welcome" message in the browser.

Does anyone know what the URL should be for the configuration/setup page is?


We have a Denon AVR X4300 which is connected with speakers and we have surround sound for music, radio, etc.

Back of Denon:

We are having problems connecting FM internet radio stations to our Denon AVR X4300.

At most, 3 radio stations connect with use of internal FM radio antenna connected to Denon AVR X4300.

A different radio in the room, which is a basic radio with antenna, has over 10 radio stations it can connect to.

1. Which provides the best quality radio over the surround sound system; Internet radio or external FM Antenna?

2. If external FM Antenna is best quality for radio, what would be the best external/ outdoor FM DAB radio antenna to use for Denon AVR X4300?

3. No point in buying and installing an external antenna and then finding out the the sound quality is better on one of the internet services.
It would be redundant and annoying to finding that out later.

Hi All,
We want to build a custom M2M antenna having a LTE and WiFi antennas inside.
It should work between -40 and +85 Celsius degrees.
The problem is that we cannot find a supplier for a low profile antenna enclosure.
Does anyone know such a supplier?

We have a network with two VLANs associated with their own subnets.  VLAN 1 is tied to SUBNET 1, and VLAN 2 is tied to SUBNET 2.  We use subnet 2 in a second section of our building.  The backbone is Cisco catalyst 3850, and the problem right now seems to be almost entirely happening with only WIFI users in the "subnet 2" area of the building, which are Cisco Meraki APs.  While users have been getting IP addresses dynamically without issues for some months now, they suddenly are no longer able to get an address thru DHCP.  If I statically assign the IP, it works.  There are hard-wired desktops on the 2nd subnet that are working fine - those are DHCP, with 4-hour leases, incidentally.  In the "SUBNET 1" area of the building, users are working fine on WIFI or LAN, without issues.  Nothing that I know of has been changed on the netowkr - no work or anything like that has been done over the last week, when this started happening.  Could this simply be a glitch with the Meraki APs or the AD server??

Thanks for your help
From the console port what is the command to change the access point from Mobility express to capwap mode.
Is it possible, on a Cisco WLC, to blacklist single or multiple AP's from joining the WLC?
I know how to block clients by adding mac addresses but does that include mac addresses of AP's?

Any help is appreciated?

Thanks S.
Android Latency using Ubiquiti AC-AP-PRO.

I have a network with 12 AP's above. The underlying layer3 switches are Dell and the POE switch for the 12 AP's is Ubiquiti with 1Gb connections.
I have done ping tests as attached and the normal stuff checks out, (WiFI device to router, servers or fellow Windows PC's etc).

What doesn't fully check out is mobile devices, mobile printers and Android Point of Sale devices . Their latency is erratic or so it would seem with 2ms, then 500ms response times like a yo-yo, averaging 150ms with no packet loss!

With so much testing done on AP settings, including shutting down all WiFi AP's except 1, and removed all Wireless devices expect for 1x Android device and the result remains the same.

I came to the conclusion that Mobile devices, especially Android and the cheaper WiFi devices do operate like a yo-yo in terms of Ping(ICMP) response, however I need confirmation please.

Hope you can assist?
