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.

Hi Experts,

We have 20 Open Mesh Wireless Access Points in our building serving over 250+ Clients. Everything was running fine until we added 2 new SSIDs and tagged them on VLANs. These access points are connected to Netgear POE Switches and All these switches are connected to our Netgear Core Switch which is backed by iBoss (Firewall and Filtering) and Sonicwall (As a Router).

After we added two VLANs, our wireless network has been unstable since. We cant airplay to Apple TVs, Cannot connect our wireless computers / iPads to our 2 newly created SSIDs most of the time.

I did the VLAN for the first time and could be doing something wrong on that front. I have tagged the ports where i have access points connected and the ports that connects to the core switch. On Core Switch, i have tagged the ports that connect these switches and the port that connects with the iBoss.

Please let me know if you need any additional information on this issue.

I need some help if possible.  

My school is very much behind the times, so we are in need of upgrading.

Our president wants specifically to have wireless connections (literally no wires needed to connect a laptop to the system), a very simple way to record high-quality video and audio in the classrooms, and the ability to broadcast class sessions online in real time.

Can anyone give me some suggestions on this?

Hi,

In our training room, which sometimes gets reconfigured with no tables for an open space, we are looking to get wall mounts that will allow items such as a keyboard to sit very tightly against the wall when it is not in use and which can be pulled out from wall when needed.

The wall mount adjustable keyboard tray with an extendable arm should meet the requirements below:
 
1.       Extendable arm with full range of swivel motion which can rotate left and right with ease.
 
2.       Height adjustable arm which can be adjusted upwards and downwards. It will need to appear as if it is sitting on a table where a person is using it. Also, when moving the arm to the position we need it to be in, the arm should lock in place.

3.      Wall mount track to allow for extendable arm to be moved vertically so extendable arm can be moved lower when in use and higher when not in use.

4.      The tray should be foldable upwards, downwards and be lockable so that the tray can be placed tightly against the wall.

5.      The wall mount tray should support the weight of objects such as a keyboard for weights up to 15 kg.

Thanks,
Robbie

Hi,

We have a Microsoft Surface Studio display which has a PC built into it.

In our training room, which sometimes gets reconfigured with no tables for an open space, we are looking to get wall mounts that will allow this Display which has a PC built to do the following:
 
1.       Sit very tightly against the wall when it is not in use. Out of the way so that when the room is full of people, people will be less likely to brush against it. Also the training room is small, so the flatter it fits everything against the wall the better. Also, the small PC in the mount should be tillable so that it can be tilted downwards to sit better against wall.
 
2.       When using it, we need to be able to put it out from the wall, and have the ability to pull it downwards adjustable to the height we want. For example, it will need to appear as if it is sitting on a table where a person is using it as their work desk PC.
 
3.       We are looking for something also that looks very well, visually.
 
At the end of the day, what it will be for us is, when not in use, there will be no work desk in the room, the base unit and the display  will be folded flat against the wall. When in use we want lots of adjustments, and that it holds the position adjustment that we set so that it appears to be sitting on an office table.

I manage a small legal office and have a SonicWall TZ 400 wireless that covers the current building ( 15 people on the LANand only one using wifi)
The owner of the company will be expanding into a separate building across a 30 foot Breezeway next door.
I have tested the current TZ 400 Signal and it "peters out" just outside the current office facing the new office space.
 the new office space will only have two people in it)

I cannot move the existing TZ 400 closer to the new building. ( I cannot use the AC wiring to extend the wifi)

QUESTION:  SonicWall just came out with a new "mesh" Sonic "WAVE" that are around $850 each . And it requires yearly fees but support is probably great and an integrated package may make sense.  But I don't even really know if the "Wave" is the right product.  Will a SonicWall Point that not on a ethernet lan act like a mesh ?

But it  seems like a pricey solution  and I might really need two of them ( $1700)
One to boost the TZ 400w inside the edge of the existing office and one to pick up the signal in the new building.
I would like to have a ethernet port from the  device in the new building and would also like to lower the cost (above)
Does anyone suggest the SonicPoint or Ubiquity or Meraki or even Google  Wifi mesh to accomplish this ?

I have a wireless network with a bunch of wireless repeaters all from SonicWall. When I am connected to one of my repeaters I can ping the company server and it responses with no loss packets. I can browse out to the internet no issues. However when ever I try to connect to my company drive It says it can;t make the connection

What could be the issue?

We support a church that uses electronic hymnals via an app on their mobile devices. During services they can have up to 500 members trying to connect to 4 Sonicpoint's with the same SSID. My question is, Is there a way for the sonicpoints or the firewall to distribute the user connections equally between the AP's?  

Right now most users can't connect and the ones that are have terrible connections (speed). Which I assume everyone is connecting to just one AP.

I thought about sectioning off the pews RF,LF,RR,LR . Then create SSID's associated to those sections. But there has to be a better way.

Thanks in advance for your help.

New Tabletop Appliances Blow Competitors Away!
New Tabletop Appliances Blow Competitors Away!

WatchGuard’s new T15, T35 and T55 tabletop UTMs provide the highest-performing security inspection in their class, allowing users at small offices, home offices and distributed enterprises to experience blazing-fast Internet speeds without sacrificing enterprise-grade security.

I haven't used my Surface Book for a week or two. Turned it on today, and the surface arc bluetooth mouse won't work.  I can't get anyone on the line at MS Support; and the canned advise doesn't work.  Any bluetooth experts out there who can give me a hand?

So, editing a few hours later.  The issue here is that ordinarily what one does is to open the services option, and go to the bluetooth page, then You click and the thing connects with your bluetooth item, in this case an arch surface mouse.  But unlike in the past two years, the two can't pair. So the mouse doesn't work.  This has worked fine for two or more years ago that I have had a Surface Book.  Something has changed.  What?

I have three TP-Link EAP245 access points managed by an EAP Controller. The speed on any of those three APs is very slow in compare to the wired Ethernet speed (internet). Measured wired speed was 495 Mbps down, and 113 Mbps up, but the Wi-Fi connections are between 7Mbps and 19Mbps from laptop or phones. There are 2.4 Ghz and 5Ghz radios enabled, and one SSID.

Are there some EAP controller or EAP245 settings that I could tweak to get this going?

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 10.0.0.1 255.255.255.0
To change the gateway: capwap ap ip default-gateway 10.0.0.2
To change the primary controller: capwap ap controller ip address 10.0.0.3

3800 Series:

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)

http://uk.tp-link.com/products/details/TL-WPA4226-KIT-V1.2.html

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

http://www.tp-link.com/us/products/details/cat-5506_Archer-C2.html

I setup as Access Points.
I disable dhcp, wan, use separate channels, disable firewall,nat,guest network. I set dns to 8.8.8.8 & 8.8.4.4
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.

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.
