I have no Broadband Internet Service in a building of mine, so I use a TMobile Hotspot device for WiFi (an Alcatel Model MW41TM-2ATBUS1-2) which uses my Cell Service for Internet.
I need a Plug-able Ethernet port somehow, and this device has no ports.
How can I get to where I can plug in an Ethernet Cable that has Internet access?
I was thinking like ... setup a Router in Bridge mode and/or use a Router to extend the network. But so far I an unable to get that to work ... wondering if I need a different device or maybe those Hotspots are unable to be bridged/extended.
Any ideas?
Thx all in advance.

I have an office with a very basic network, maybe 8 people max.

Unmanaged Switch---CloudTrax AP

We are having issues with intermittent wireless issues. Maybe once or twice a week, wireless will completely lose internet access. They will still be connected to wireless, but cannot reach certain internet locations, such as Pinging fails, but something like will work fine. I run a tracert to, and the connection seems to drop about 8 jumps out of our Firewall at some random Comcast hop. At this time, wired devices work fine, no issues. And they take the same path as wireless. The only resolution we have found is to reboot the AP.

I have checked the Firewall, no issues I can find there. I've checked the packet makeup of both wired and wireless devices leaving the Firewall, and they are exactly the same except source MAC.
We have replaced the AP, brought the troublesome AP to our office and it works fine, the new AP has the same issues.
Comcast has replaced the modem, this didn't do anything.
I played around with the CloudTrax's settings, they are pretty basic but it hasn't fixed anything.
I've looked for loops, there is about 8 PCs in this office so it wasn't hard, nothing there.
The issue exists on phones and laptops, running anything from Win7 to Win10 and iOS/Android.
We replaced the Firewall(it was due to be replaced anyways)

It's worth noting, that while a …
Maybe I'm overthinking this, but how can I mirror a PC screen (or extend) to a TV across the room without using an HDMI cable or similar and without using WiFi? The PC is a regular wired desktop PC. I believe I've seen products in the past that could do this without wifi, but everything I find now requires wifi. While I could perhaps purchase a wifi USB dongle for the PC, I've seen this cause network issues when a wired and wireless network are both active on a single PC, so I'd prefer to avoid that.

We had a power outage over the weekend and the server room did not switch over to the generator so we lost power to everything.
One of the things that didn't come back right was the wireless controller.

We have two Cisco 5508 in HA configuration.
The Primary did not come back so everything is running off the secondary, which is working fine and everyone has wifi.

When I connect to the Primary with a console cable I can see that it's asking me to give the system a name, making me think the WLC is wiped.

What is the best way to add a "blank" WLC to the existing WLC so they work in HA again?

Thank you
We have an HP 2530-24G-PoE+ (J9773A) where our port 11 keeps going on-line and then off-line. The device that we have connected to it is a wireless AP that uses POE. When I go into the logs of the switch all it says is that Port 11 is now on-line and then the next line is that it has gone offline. With no other information. What can I do to find out what's wrong with that port? I'm still very new to programming on a switch.

Have the following Scenario and need your advice for the best technical solution to be used.

- We have customer who is working with Oil Shale
- Mine Dimension : 3 KM x 1.8 KM x 80 Meter Depth  
- Around 15 machines working in the mine
- Machines need to be connected to the internet to send data either WIFI or GSM.
- The Customer Offices has Internet connection (Microwave)
- Distance Between Offices and Mine is around 3 - 4 KM
- One the Mine Surface - There is GSM Data Coverage (Still weak) but as the machines go down it looses connection

Our Issue we need a internet coverage for the machines, what do you recommend ?

Thank You

What is the replacement of Cisco Small Business High Power Gigabit Power over Ethernet Injector (SB-PWR-INJ2-UK)? I want to buy Power Gigabit Power over Ethernet Injector.

I have a customer who is a General Contractor.  He wants me to add cameras with spotlights to a job site.  He said he could give me a pole with electricity.  I know Ring has a camera with spotlights but I dont think they have built in LTE which is my first thought.  I did some research and found Reolink Go and Arlo Go.  Does anyone have any experience with this cameras or have another solution that we can consider?

Any info would be greatly appreciated.
Hello all,

I have this really decent USB wireless digital mic device:
Samson XPD1 Lavalier USB Digital Wireless System https://www.amazon.com/dp/B014803CMK/ref=cm_sw_r_cp_api_i_QzIvCbSJBBCRN

It works great with my computer, but I’d love to adopt this to also work with my DSLR camera.

I figured that I could build an interface to provide 5vdc to the USB based transmitter and extract analog audio with an D/A converter. But I’m currently um... lazy er... too busy at this time. LOL  

Can anyone suggest a ready to purchase adapter that can do this?

Thank you,
Airwave appears to have stopped graphing clients and usage about a month ago. Is these a process that needs to be re-hupped to get it going again? Please advise on what's likely the issue.

hi folks

i got an interesting issue and haven't figured out any clue to fix it.

a Toshiba laptop (Satellite C855D-S5950) running Windows 10 shuts down its WiFi on its own.

the issue was initially noticed as the user could not press F12 key to switch wireless on or off, then i noticed that actually WiFi and Aeroplane Mode both not worked. WiFi adapter looks fine under Device Manager, and the adapter's Properties look fine as well. no WiFi adapter settings in BIOS.

in Windows 10 Settings > Wireless, WiFi is shown off. if you switch it on, then it will switch off after a short while.

do you have any clue about what's going on there?

How can I find the up address of the DSL modem behind a router?  
Attaching the DSL modem directly to a computer did not help:
The ipconfig showed a 169 up address.

I have a TP-Link 3150 v2 wireless ac router.

Does it support access point and repeater mode?

If not, please suggest some wireless ac routers that act/support in Repeater and access point mode.

Reach out to me for any questions.

Thanks for your support.

Just received the Vonets device & tried the above suggestion of setting it to "Bridge + Wifi repeater"
followed by steps in page 7 & 8 below:

I'm able to use it as Wifi repeater ie by placing it say 12 ft away from my Wifi broadband
router & with my laptop is a 'blind spot' of my bedroom, my laptop could connect to that
device "wifi hotspot" & get to Internet (which previously my laptop cant get to Internet).

Now, the other requirement as per the original enquiry in the EE link is to connect it to
a LAN port & serve as Wifi hotspot: can't get this working: when laptop tried connecting
to this device's SSID, it prompted for password which when I enter, it simply gave the
message "password not right" though without connecting this device to a LAN port, the
very same password works.   I've tested connecting the built-in LAN cable to LAN port
OR (ie one at a time) using a LAN cable to wire the WAN port of device to wall's LAN port.

If this works, the next thing I'll need is to connect this device to my laptop (while my
laptop is connected to a LAN port on wall & serve Wifi hotspot to others
I have this Bluetooth headset (Wireless Model ST-006) and i tried to pair it to the windows laptop so i set the headset to pairing mode. i waited for quite a while so it thought something was going on. i tried in other devices like an iPad and a mac book and they worked perfectly. i then went to device manager in the windows laptop and show hidden devices and found my Bluetooth headset named 'ST' so i just simply uninstalled it. after i did that i tried pairing it again and still didn't work. after i restart the laptop i realized that the 'ST' was reinstalled. so i tried disabling it instead and still didn't work. i then went to the events tab of the device and saw it saw that is was reinstalled by this thing called "bth.inf" . does anyone have a solution for this?

We are looking for a security camera that can alert the user if motion is detected and does not take up much bandwidth.

We have Nest cameras which are on 24/7 but the problem is that they take up a lot of bandwidth.

Here is my criteria for the camera we are looking for:

- Less than €100
- Does not constantly take up bandwidth 24/7; only uses bandwidth for tasks such as notification sending, if user wishes to access pictures taken by the camera,etc.
- Does not need a subscription
- Can send a message to a person's phone when motion detected or when the camera sees someone
- Released in the past 2 years or more recently

What would be recommended as the best security camera with the above criteria?

Trying to connect WGPS606 Netgear print server on a network but the setup fails when detecting the print server to a windows 10 machine .  I have checked the ethernet connection from the print server port to the ethernet in the back of the computer . I understand that the printserver does not have dhcp so how will it detect the print server using the ethernet port ?
I have a HP laptop which every 3-5 days loses the WIFI device. It looks like is controlled by the HP Support Assistant, and when it disappears in HP Assistant it shows "Disabled by Device Manager", so what I have to do every time is reinstall Wireless driver from HP web site and after that it reappears back under Network Adapters. Has anyone seen this happened before?
Is there a solution to it? Thanks.
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
