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.

We are implement the multiple VLans and Wi-Fi  in our company:
Vlan 1:default Vlan (
Vlan 2:Office Vlan(
Vlan 101:production Vlan (

We are using Aruba instant virtual controller to control all the APs. In the core switch default gateway is which is the router Interface.

We had no problem for the connectivity using wired. But we found the if connected using office wifi (Vlan 2) and try to reach those device have wired connection in (Vlan 101) is no issue. But If the device is connected using Wi-Fi then we can not reached.

IN the Wi-Fi controller we never set any policy to block it.Please advice ?

Hi Experts,

I am installing new wireless equipment at a very small motel this week. They have AT&T business internet and just want to provide an SSID and password/key to guests to connect. No splash screen or anything like that. They were originally using Netgear signal boosters that you plug into wall outlets, but customers stole them.

I told them I would only use pro-level equipment, so I have ordered 2 UAP-AC-PROs and the Ubiquiti 8-port 60w PoE Switch for 12 rooms. Eight rooms are in a 2-floor building, four on each floor and the other building is just four rooms on a single floor. I plan to install one AP on the ceiling in room 3 (middle, bottom room) of each building, including the two floor building. The rooms are small so I think this will suffice.


Do I need to order a security device or new router? Can I use the AT&T provided router and connect it to the Ubiquiti PoE switch and configure the WAPs using the Ubiquiti controller software installed on the office PC? And will that software without a security device or new router be able to provide two SSIDs?

The owners are trying to save money (of course!) so I wanted to see if any other gear was necessary. It appears that the solution I've provided will do the trick, but it is not ideal security-wise. Any advice is appreciated!


Hi Everyone,
I have a Dell D830 with Ubuntu 17.04 installed.  It has a Broadcom Wireless adapter but:
>I cannot identify any WiFi network
>Appears that the WiFi adapter is not working

*I verified it is using a 3rd party adapter by following:
>Click the button at the far right side of the menu bar and select System Settings.
>In the System section, click Software & Updates.
>Switch to the Additional Drivers tab.

Any suggestions to make the WiFi work?
Strange scenario where windows 10 on one network when trying to connect will go to blue screen which error points to the wifi driver but this will eventually happen on a wired connection too but it is not immediately on connection sometimes taking 5 or 10 minutes.  Move to a totally different environment router, network, ssid and no sign of trouble.  Not only have tested this on each once but twice spending a few hours on each.  Could this be related to the routers vs the laptop computer and the wifi card?  The one that fails is a cox router modem combo single unit.  The one that works fine is a Mediacom with separate modem and router setup.  In addition if I use a different laptop on the network with the problem scenario I do not have a problem. The laptop with the problem is an hp 15-ay192nr running the latest version of windows 10 updates and drivers from hp.  Worked with hp support for an hour and they could not resolve the issue.  They said reinstall the entire machine.  But it works great on the other network not a sign of problems.
Any thoughts on the  ARUBA IAP-205 WIRELESS ACCESS POINT s?

I have about 4 or 5 outhouses and I want an goof Wi-Fi solution.

Thank you.
Can someone tell me what the CLI command is to remove a VLAN on a 2504 (AirOS) Cisco wireless controller?

Dear guys, can you please explain the advantages and disadvantages of Wireless Transmit power? Why do they always recommend -65 dBm for users? If I increase the AP's power to the maximum, is it always good?

These attached pictures display the coverage when changing AP's power. I use VisualRF to test HP AP Aruba 205H, can you suggest some ideas about the results?

- Red color: -45 dBm
- Orange: -55 dBm
- Green: -65 dBm
- Blue: -75 dBm
A customer of mine has a problem where he often loses small items (such as keys and Bluetooth headsets).

We are looking to find the best system where a chip can be put on these small items and then these items can be located using an Android or Apple iPhone.

What are some of the best systems for doing this?
Got this cam Samsung from Costco SNH-V6431BN/US

I was able to connect to my WiFi but the connection is constantly dropping and I need to re-setup every time after that.  Does it have to be very close to the WiFi router?  Other devices are OK on the same router and not dropping.

2nd question.  Is it only designed for the mobile app?  Manual doesn't provide any instruction via the regular browser.

The wireless on the Mac is giving me issues, I have an external one (USB) how do disable the built in one and force it to use the external one (USB)?

I'm a system administrator for a company that has about 500 computer users. One of our job sites currently has a mesh network setup. There is one main building where the internet comes in and using a Cisco wireless outdoor bridge that connects to another building point to point. The signal to that building drops significantly from around 25 Mbps to 5 Mbps. The equipment currently in place is pretty old, probably 10 years old now.  The other 3 buildings feed off the 2nd buildings signal which is already low, which means there's is lower. The entire site is about a mile total. The main building is about .5 mile to the second building and the other buildings are less than half mile or so from the second building which is where they get their connection from. Certain buildings drop their internet connection pretty frequently also.

I'm looking for some recommendations on good quality outdoor bridges that will help this job site improve their internet speeds and reliability.
Dear fellow Experts Exchange members:

I have an unusual question that requires the input of fellow members who have had hands-on experience with *ANY ONE* of a set of USB wireless AC network adapters.

Here is my situation: I have an office with two wireless access points (one on the left side and one on the right side of the building).  I have dropped the transmit power of each AP to try to get the wireless adapters in their three-or-four laptops to roam to the nearest AP when the users walk from one side to the other.

However, I am unable to find any "Roaming Aggressiveness" setting in the hardware properties of the wireless NIC for any of the current wireless NICs (internal and USB) in the laptops.

As it stands, the users all experience drops when moving from one side of the building to the other due to the wireless adapters in their laptops stubbornly trying to use the AP on the other side of the building despite there being an identically-configured AP literally right overhead.

I have a list of wireless AC adapters recommended by various sites, and I would like to know from any Experts Exchange members who have first-hand experience with *ANY ONE* of them if their device drivers provide a "Roaming Aggressiveness" setting.

Here is the list of wireless AC adapters:
  • Alfa Long-Range Dual-Band AC1200 Wireless USB 3.0 Wi-Fi Adapter
  • Asus USB AC56 Dual-band Wireless-AC1200 Adapter
  • Asus USB-AC68
  • Buffalo Technology AirStation WI-U2-866D
An office around 2,000 sq. needs a solid AP or AP's .

Which one would you recommend.

I know that the ubiquiti are good, but I don't like the installation process.

Also I have a PoE switch so I need it to work with it.
How can you determine the MTU setting of a access point on a Cisco 5520 wireless controller from the command line.  From the command line, is there a command which will display what the access point MTU setting is?

We need to install a Wireless connection between 2 building (about 30m apart), the devices will be put on the inside the windows so not on the outside of the buildings.

The devices will need to support bridged mode as they are just used to connect the networks that are on the each side, no client devices will connect to these devices.

Has anyone got a suggestion for a set of devices or know if the Cisco Aironet 2800 or 3800 can do function as required above?
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.
Is anyone aware of issues (and work-around) with setting up a Cisco 5520 wireless controller SNMPv3 credentials?  I can get my controller to work via SNMPv2 but not version 3.  I have other wireless controllers (5760's) which have no issue in communicating with my Cisco Prime via SNMPv3.  The only one with issues is my new Cisco 5520.
Are there known issues with SNMPv3 and the Cisco wireless controller??

Appreciate any help


Sriram from India here.

Does the Acer Aspire E5-553-T4PT Notebook (UN.GESSI.001/ APU Quad Core A10-9600P /4 GB RAM /1 TB HDD / LINUX),Black have wireless ac and expandable DDR4 RAM upto 16 GB?

Please provide the official Acer website URL for this laptop's specifications.

Please revert for any questions.

Thanks for your support.

Warm Regards,
Is there a how-to guide to deploying wireless access points in a small business?  Something that will help in deciding the number and placement of APs based on configurations of the space , the building materials, (gypsum wallboard on metal studs),  the number of PCs to be served. and the optimal wireless standard e,g, N, AC etc.

Where can I setup a Linksys EA8500 to allow rdp (port 3389) to internal pc through port 8080 ?

For years we have been using directional Black Box LWE120 equipment for outdoor wireless connectivity in the range of 500' - 1500'.  Each radio only costs $100, plus they are easy to configure, and they work great for years (none has died yet).  Better yet, the support services from Black Box have met every need, talking to real live American techs the moment I call them.

The bad news is that the company is phasing out this excellent product line with no replacement in sight.  So now I need to start all over again with a similar product, preferably like my description above.  And, I will need a product line that includes an omnidirectional model like their LWE121, and be able to set one up as a repeater where I don't have direct line of sight between the two offices--like I'm about to have to install for a new customer.

Finally, I go back to great support...someone recently said to check out Ubiquiti products, but I read numerous complaints from IT guys saying they never could talk to a real person, and had trouble getting ANY support, etc...headaches I definitely don't need.  

Any suggestions for a product line that meets these criteria will be greatly appreciated.  TIA
Hello I have a UniFi AP Ubiquiti access point I had to do a hard reset but my question is should I name the SSID and web key the same as the main router in the office or would that create trouble?
Is there a printer that is portable and I can do two sided printing legal or letter paper wirelessly from my iPhone?
I pay $222/month and I get:

- Land line
- FIOS Internet
- Cable TV

But I watch only a few channels and feel ripped off.

What options do I have?

I like having a land line for a phone conversation that is near perfect, which I sometimes need for job interviews.

My cell reception from home is not terrible, but it fluctuates. Hence, the cell network would be a high cost way to get Internet access.

I really do not want to go up on my roof, three stories up to put a put on a satellite dish. Plus, I may not be living here much longer.

Do I have any options?

I generated a self signed cert for my vWLC using this guide: Guide. We recently purchased a wildcard cert from Digicert for other authentication uses in our domain. Is there a way I can use that wildcard cert to authenticate on the vWLC as well or are these two different types of certs?

This post: Wildcard Cert guide leans me towards "no" but I'm uncertain. Any help is appreciated.
