Dear Experts,

I am not able to get tech support to help me with this via chat and I can't get them on the phone.

I can connect to the devices via SSH. Not sure what commands are needed to run to get the devices adopted.

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 stay at a campground during the summer. They have free WiFi but every time you connect, an internet page pops up and redirects you to a page that says click to continue for free WiFi. You do not have to enter a username or password, Just click continue.
Ideally i would like to have a wifi access point setup that i can connect my laptop and phone to.
I started looking into setting up a router with DD-WRT but have no experience if that would work in this situation.

I have a set of headphones I bought at Harbor Freight Tools (yeah, I know, big time cheap) and went to hook them up, but the TV I'm using, while flat screen (and about 5 years old, and is not a "smart" TV) has NO audio output plug. I am also using Google Fiber, if that makes a difference. I'm not a tech type and need a relatively simple solution.

The TV in question is LG Model LS3400. User manual easily available online with good graphics of the back panel.

Is there a simple solution for this or do I wait until it's time to replace the TV?

I would like to know if there is a web site which lists all the location of 4G and 3G mobile phone transmitters in the UK and also the frequency used e.g. 1800mhz etc.

A warehouse / manufacturing environment with low ceilings ~ 15-20 ft are using Cisco 3702i APs . The APs are running in Flex Connect mode through Cisco 5520 WLC running 8.2.141.0 code.   The site is facing frequent disconnects with their handheld units. These scanning guns have the following models (quantities) : Zebra XT15 (9)  , Zebra RS419 (9), and Zebra WT410N0 (3).   They face random disconnects. Whats weird is sometimes a scanner will be conneced to wireless , it disconnects and is unable to connect back to the SSID at all and will error out saying out of range.  It seems like the issues get worse when all of the scanners, handheld units are in use which leads me to believe that this might be client device issue. What can I do on the WLC side or recommend to the site for RF unit device configuration or otherwise to address this?

I have a hacker who has compromised my network, devices and my life for over a year. I have found various devices connected to my lab top via blue tooth, unknown devices on my wifi network and have collected a bunch of networking logs and see things on there that shouldn't be there, I believe. It's a lot of information that I really don't know how to read and I don't know what information is important. So I'm looking to hire somebody to review the logs and information that I found and tell me what information should be looked at more closely, what information needs to be investigated further, etc.

Definitely willing to pay.. Contact me privately if you have history in this area.

Simple, centralized multimedia control

Watch and learn to see how ATEN provided an easy and effective way for three jointly-owned pubs to control the 60 televisions located across their three venues utilizing the ATEN Control System, Modular Matrix Switch and HDBaseT extenders.

I have cisco 5508 lan controller and 2702i WAPs with static IP address. I want to remove static ip address and assign through cisco ios dhcp server. I'll do the following:

On cisco switch:
ip dhcp pool <pool name>
network <ip network> <netmask>
default-router <default-router IP address>
dns-server <dns server IP address>
option 43 hex <hexadecimal string>

Then go to WLC GUI and go to each AP and click "Clear all config"

On switch the ports are configured as:
switchport access vlan 111
switchport mode trunk
switchport trunk native vlan 111
switchport trunk allowed vlan 9-11, 111
spanning-tree portfast

All WAPs are in flexconnect mode.

Are these steps correct? If not, please list detailed steps. Thanks.

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

I have been trying to figure this out for a while. We are using Mikrotic for public wireless. We currently have separate hardware. One for users who have accounts in our radius server to login with and a second where others can connect to and pay for Wifi.

We are trying to combine this down into one.  So when they connect, they are on the login page for with the pay wall.  Trying to make a button that says subscribers click here to login. That link should go to the radius login page.

Currently the paid one is in hotspot and the radius is in hotspot2, but I can't figure out how to get the link to point to the hotspot2/login.html

The documenting hints on how this can be done, but it is very incomplete.

Any help on how this could be accomplished?

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 :(

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 went in to swap out a Vodafone ADSL router in an office with one server running SBS2008, 4 desktops running Windows 7 Pro & 4 laptops, 3 running Windows 7 Pro &1 running Windows 8.1 Pro. They are all connected to an unmanaged switch which connects to the ADSL router they also have 6 iPhones which connect wirelessly.
I had to disable the wireless on the router as anytime an iPhone connected the internet would freeze & both the phone & all the pc's/laptops would lose internet until i turned off the WIFI on the phone.
Someone had already done a factory reset on the old ADSL router so i couldn't copy the settings & i'm wondering have i set it up wrong?
I've disabled DHCP on the router as the Server manages it & all the desktops & laptops have static ip addresses.
I did try & leave DHCP enabled with a scope of addresses that weren't being used but that resulted in the same connection issues.
Is there a way to set up the router so that the iPhones can connect without DHCP being enabled?

Free Tool: ZipGrep

Free Tool: ZipGrep

ZipGrep is a utility that can list and search zip (.war, .ear, .jar, etc) archives for text patterns, without the need to extract the archive's contents.

One of a set of tools we're offering as a way to say thank you for being a part of the community.

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.

Hi Experts,

One of my clients asked me to generate a report of the availability of each device in cisco Prime Infrastructure 3.0, using the Device Health report I managed to generate an availability report for the wired network, however the AP availability isn´t generated on this report and I didn´t find another one that shows me the availability for my access points, can someone please tell me how can I generate the mentioned report.

Thanks in advance.

My client has 3 physical locations, all just switched over to Charter Spectrum Business running on an Engenius ESR600 wireless router.  2 locations have no problems ever.  The third location has 6 computers, of which 5 will lockup using the AMS360 website.  The computers have never frozen except during AMS360.  The computers never once froze before switching to Charter Spectrum.  The 6th computer is the only laptop in the office and doesn't use AMS360 much if ever.  So I began testing power to computer stations, but no power issues could be found at the two highest occurrence PCs.  To make things worse, the problem never effects two computers at the same time.  The software can run in IE or Chrome, and the problem are the same on both browsers.  Most of the time, the browser is not responding and never recovers, but you can open another instance of the browser and work just fine.  On a slightly more rare occasion, the user will report one of the AMS360 tabs will go gray (Not responding), and when the go to another tab and work there for a short time it may lock up (No mouse, keyboard or any input).  They have waited an hour to see if anything will change, which it doesn't.  I don't really know the actual frozen vs not responding broswer %.  I have seen first hand an unresponsive PC at this client and the browser not responding.  All computers are Windows 7 SP1 64-bit.  They are a mix of Lenovo ThinkCentre and Dell Optiplex computers.  I have installed all updates and drivers …

Hello Experts

We have a client with cisco aps and controller, when trying to add 2 more aps they cant seem to connect those extra 2, just wondered if this is something you could advise with. We believe the controller is licensed for active count of 25 Aps, and there are currently approx. 10 onsite, with the 2 we can’t seem to connect. Is that possibly where they have added , changed, or moved around aps?

I have the DCS-932L-B1 camera and I downloaded the mydlink lite app on my cell phone. I did all the steps to connect to my wifi, including pushing the WPS button as well as plugging the ethernet cord into the wifi adaptor and it keeps telling me it cannot connect. Also, I have a chromebook for a computer and I cannot download the setup wizard that i keep getting referred to do. What else could I try to do to connect to my wifi?
Thanks!
