We've just moved into a office we're renting that has ethernet jacks in the wall and also has WiFi.  So we can connect a CAT5 from a laptop to an Ethernet jack in the wall and get online.  Or, telling the laptop to look for networks, it finds a wireless signal that also gets us onto the Internet.  Now I'm trying to understand what must be in the building to provide this.

I assume there's a cable that comes in from Comcast, or someone like that, that goes into a big router in a closet somewhere and that router creates a hundred or so RJ45 Ethernet ports that get wired out to the offices.  This router must also create a WiFi signal that can be picked up in any office.  

Does this sound about right?  

Within our office, are devices that connect over the WiFi connection on the same network as devices that plug directly into the wall RJ45?

Will each office have it's own network, that other offices can't get onto?  

Thanks for any insight here.

Important Lessons on Recovering from Petya

In their most recent webinar, Skyport Systems explores ways to isolate and protect critical databases to keep the core of your company safe from harm.

I just got a Windows 10 laptop and it saw the WiFi from my AT&T router so it got on the Internet fine.  But I notice that it also sees my desktop computer there, which has a CAT5 cable going into theAT&T router, so I guess that puts the desktop machine on the same network as the WiFi devices connecting to the router.  But if I click the desktop computer icon on the new laptop,  it asks for  a username and password to connect. It's been years since the desktop was set up and I don't know the username and password.  Is there a way I can get this from the desktop machine, itself, which I can log onto from the keyboard as an Admin user?

Thanks

People moving into the new office but the network gear may not be ready yet.  Looking for a quick alternative for WiFi access just so users can go online.  
Saw that thread below from 2015 where a person says they ran office of 30 off this device following hurricane Sandy.
My office would be about 10-12 people day one.

Would that work as a temp solution?  Any suggestions appreciated.  Thanks!!

Hi Experts,

I am trying to change where the Cisco Aironet 2600 gives out IP addresses from. It is setup to give out IP addresses from Windows DHCP server but I am not able to find the option in the UI to point it to the new server. Can someone with this UI advise please?

Thanks

I have a Windows 10 Professional workstation on a mobile cart that uses a WiFi connection to connect to our manufacturing Access Points. We have a mapped drive to a share on our file server for this workstation. The problem I have is that when the computer is rebooted, the WiFi is the last thing to load and work.  When the WiFi finally connects the mapped drive shows the red "X" and I get a notice that not all mapped drives have connected.

My Question is: How do I set the WiFi to connect before it tries to reconnect the mapped drive?

Hi

My client noticed the absence of the usual Wifi SSID in one area of his hotel and asked me to investigate

Apparently the local AP, a Zyxel WAC6502d, is now back to advertising it's default SSID : ZYXEL

From what I gather it was initially setup in AC Discovery mode and the NCX2500 provided it with its running parameters

So I disconnected it and connected my notebook directly to it (using a PoE injector of course)

It didn't provide me with an IP address; strange, I thought that the majority of APs functioned by default in stand alone mode

The manual indicated that by default its IP address is 192.168.1.2 therefore I configured my notebook's LAN interface accordingly
No joy, I can't ping the AP

I checked to see if the ZYXEL SSID was still being advertised and what do you know ? No ZYXEL SSID anymore.

I'm sure that there is a reasonable explanation for this situation

Anyone out there care to share their know how please ?

thanks

Nothing ever in the clear!

This technical paper will help you implement VMware’s VM encryption as well as implement Veeam encryption which together will achieve the nothing ever in the clear goal. If a bad guy steals VMs, backups or traffic they get nothing.

This problem started about a week ago with 1 of my 15 Wireless Lan Controllers.  There are no errors and the controller just reboots itself.  I have monitored it this morning and it has restarted no less than 5 times in an hour.  Does anyone have any ideas why this would randomly start happening.  It comes back with no problems or errors.  Stays up for about 15 minutes and goes back down.  I have checked all the connections, but site is 2.5 hours away so I want to make sure I have a decent idea of a fix before we drive there.  We have had these in for about 4 years without any issues.  Never had an issue with this.  The software version is 7.0.220.0.

Hello,

I was wondering if anyone could offer suggestions on how to improve wireless performance on a Cisco 5508 controller.

I am told right below the AP there is little to no signal.

I understand there could be multiple reasons for this, any suggestions for improvements ?

There are 3702 and 1131 AP's

Hi

Currently the support provides with a very least support.

Request that send from Vendor :

I took over a job at a local company and they have 3 UniFi AP's placed all over the building. All which over last few years have fallen off the network or the people ahead of me didn't care enough to keep them running.

My questions are a little more about setup. The AP's themselves are older and no QR codes. The M/N: UniFiAP.

I have a power supply with 2 ports POE and the other is LAN that are in the server room. There is one Ethernet wire running to the AP in the ceiling.  I was able to trace the Ethernet wire to the patch panel and I have it plugged into the proper port. I also have LAN plugged into the switch.

The AP is in the ceiling with a solid green light now. I downloaded the software from unifi website but think i'm doing something wrong. I'm running UniFi Controller 5.5.20 and when I try to scan for the AP it wont show me it recognizes it. I also have the unifi app on my iphone and unable to enter the MAC ID Manually because my mac has no hyphens.

I'm pretty sure these AP's are at least 3-4 years old, I'm assuming that's why my iphone isn't working properly with them.

Do I have to use the unifi controller? Also how else can i access the AP? on my router or switch would they be labeled Unifi or Ubiquiti. Any help or direction is appreciated.

Hi,
 I got a Dlink router(192.168.10.1) in which i disbaled wifi.
then I got a TP-link Access point where wifi and ssid enabled.
I have connected Access point to router. setup dhcp in both access point and router. everything works fine. wifi works fine from AP getting ip in 192.168.10.1 range.

But i want to setup access point(192.168.20.1) in a different subnet to the router network(192.168.10.1).   how should i set it up to make it work ???

Hope my question is clear.

Thank you guys.

Everytime i read about rfid data transmission i read about inductive/magnetic coupling with load modulation in the near-field of an RFID-reader and backscatter coupling for the far-field, but I´m not sure if these are for passive RFID-only.

Do active tags have a completely different way of transmitting data or do they presumably use backscatter coupling aswell?

Thanks in advance.

my home has 3 wired imacs. I would like to set up wifi internet sharing on all 3 devices.
Are there any issues with using the same ssid and and password for all three devices?

Some of the locations we are thinking about putting security cameras are close to existing power, but NOT close to existing Internet, threfore we were thinking about doing POE on the ones close to existing Internet and WIFI for the ones close to existing power, but NOT close to existing Internet

 1. Do you think wireless cameras are good for BUSINESS use or should I stay with WIRED cameras ?

 2. If wireless cameras are good, what brand do you recommend for a 3 story building ?

Hi,
If i have  a multiple access points with same SSID and password. how do i figure out to which access point wifi my laptop is connected ?
is there any way to figure out rather than going into each AP and see what are the attached devices ?

thanks guys

Hi

We have 90 Laptops using the Wi-Fi network and 200 PC connected to wired network and 3 domain controller the DHCP server is installed on the DC-1.

We have a delayed login problems only with the laptop connected to the wireless network. When I log in it takes 5-6 minutes to log in and load the desktop. And after it logs in if I do gpupdate / force it takes 5-6minutes to complete and comes with this error as attached.
From the time I logged into the laptop till it loaded the desktop icons I made the note of the timings and have saved the events generated on the event viewer on 2 different logon attempts. I am not able to attache the events file . so i have taken the snapshot.

At the same time if I disable the laptop Wi-Fi network connection and connect the laptop through a LAN cable to a wired
network. It log in within 40 seconds and also if I do gpupdate /force completes in 10 seconds.

The wireless is on separate subnet compared to wired network. We have three SSIDS and for each of them separate DHCP scope is created on the DHCP server. I tried logging in connecting the laptop to other 2 SSID and still the problem remains the same with delayed login.No sure where the underlying problem is, this is happening only with the wireless network.

Please guys any help to find the fault and resolve would be really great. Let me know if you need any further information.
Thanks in advance.

Need to change WIFI properties to metered, on a group of laptops. Hoping for a batch file, or small script, an assistant can run on each. Hard drives are too small for Win 10 auto updates, attempting to stop auto download of them, so we can do them in a controlled, scheduled fashion, instead of when students are trying to use.

I have a wireless modem/router which manages the main part of my network.  Its LAN IP is 192.168.1.1 and it is a DHCP server.

I have also connected a TP-Link C60 Wireless router via cable to the modem/router.

I am wanting to configure the TP-Link wireless router to give wireless access but then have the DHCP managed by the modem/router.

At the moment I have the TP-Link router getting a WAN IP of 192.168.1.200 from the modem, but then the TP-Link is issuing IPs to wireless clients in the 192.168.0.1 scope.

Does anyone know if I can get it to simply act as a wireless repeater for the modem rather than have its own DHCP scope?
