I have a remote office that is a steel building with alot of copper piping and wires.  It is for an aggregate batch plant.  Cell phone coverage inside this building is almost zero.  I need internet in the buliding and of course a Verizon MIFI (which is what I wanted to use and have tried) does not work.  Is there a way I can attach something to the mifi and run it to the top of the building and to a wireless router or something and get better coverage or does EE have some other ideas on how I could have an internet device outside of the building and bring it into a router or possibly right into the desktop computer that needs the interent connection?

Hi Experts,

I was wondering if someone could guide me on configuring Cisco WLC 5508 as High Availability? My client has an existing 5508 WLC, and now purchased another 5508 as HA SKU and would like to set up the new 5508 as HA. Both WLCs are in the same location (same rack even). I read some guides online but maybe someone has done it recently or has concise instructions on the best way of doing this.

All tips and comments are appreciated!

Thank You!

I'm running Windows 10 Pro version 1803 on a Dell Latitude 6330.  WiFi is disabled.  The WiFi switch in Settings is set to "Off".  Turn WiFi back on is set to "Manually".  I cannot get the switch to stay set on "On".  The Network Connection icon in the system tray says WiFi Turned off.  I have tried rebooting, turning the PC off and on, removing the battery.  So far I can't find a fix.  Ethernet is the only way I can connect to the internet.  Can someone recommend a fix?

We have a job office that is in an area that can’t get Internet service directly into the office. We have provided them with a MiFi hotspot and they say the service is not acceptable. They also say that the cell phone coverage in the area is pretty good so I am curious on why the Internet service is not. The question I have is :  Is there anything that can be done to strengthen the signal of the MiFi or are there any other ways that I could get a better signal strength in this situation?

Hello Experts,

I want to add a WIFI access point to a clients network.

These are the four results I am after:

1. Limit bandwidth  to WIfi AP- Can do this with my firewall.

2. Time access control - can do this with a LYNKSYS WIFI access point device

3. Limit or strip off Webmail attachments.

4. Monitor Data Usage on the access point and limit it.

1. And 2. Above are no problem but I don’t know how to a achieve 3. Or 4.

Does anyone know how to make 3. And 4. Work?

Thanks!

I have an office with Cisco 3702i AP's.  I am getting a lot of messages in my logs showing that some of my AP's are being contained.  I have got a wireshark capture of the deauth packets.  Can someone please help me identify anything I can about the source?  I captured the traffic by putting one of my AP's in sniffer mode and dump it to wireshark.

The MAC address of the sniffer AP is f4:4e:05:12:c0:28


Thanks!

Hi

I recently setup 802.1x authentication for our WIFI network.

Windows 10 and Mac clients can connect to the network with no issues. Windows 7 laptops however are not getting prompted to enter a username or password. It just says "Unable to connect to the network"

Please advise

Thanks

My boss has a wireless network that shows up on his computer as being connected to 2 connections at the same time.  At least that is what it looks like.  It shows the wireless network of "Bison2" as currently connected to but underneath where it shows all of the connecetions in range, it shows "Bison" as connected.  He says it interferes with things which he could not explain to me what he meant by that.  When I right click the adapter in network and sharing (which shows it as connected to "Bison 2")   the SSID shows up as "Bison"

 See screenshots and let me know what is going on if you can.

How do you  define "Power Constraint element"?

Context:"Basic operation of transmit power controlTransmit power control(TPC) is an 802.11 service that attempts to hold          transmit power to the lowest possible productive level. It takes          into account the maximum power allowed by regulators, as well as          further constraints. Although designed to satisfy regulatory          requirements, transmit power control may have additional          benefits.The absolute cap on any radio transmission is set by          regulatory authorities, and is found in the relevant documents and          rules published by the authority. Regulatory maximum power may be          configured into an AP or station, or it may be learned from Beacon          frames containing Country elements. Radio transmissions may be          subject to additional constraints that further reduce the maximum          power. European regulations specify a further mitigation          requirement of at least 3 dB to reduce interference with          satellite services.Maximum transmission power is specified using the Country          element in Beacon frames, and is available to any station wishing to          associate to a network. The Country element specifies the regulatory          maximum power, and the Power Constraint element can be used to          specify a lower maximum transmission power specific to the          network."

Context: Once the new channel is selected, the AP informs nearby clients to clear the channel and move to a different frequency by including the Channel Switch Announcement IE in the beacon frame.

What does IE mean the above sentence?

I am trying to determine the meaning of the word quiet, when referring the to ability of dynamic frequency selection service providers.

"An AP can quiet a channel to test for the presence of radar." Does this means the access point prevents a channel from being used while it is testing for radar?

How does transmit power control enable the client and the access point to communicate with less power? It is because it reduces the cell sizes?

Since last year, we have been using Ubiquiti radios to connect for internet connectivity from one point of our new office to the other.

However, now we are considering to use point to point, directional antenna WiFi transmitters. Kindly recommend the radio to use for video feed of 4k of up to 16 camera https://www.amazon.com/dp/B01N0B6KSA/ref=cm_sw_r_wa_api_ysh-BbDAEKWAS   from same distance.

I recently got the recommendation for Cambium Force 300. Is this advisable or something else ?

On my work network, when on wifi, I get good results on a speed test

30/33/ 3ms

but when playing games on the phone people complain about lag and even losing wifi connection.

I am not sure why they are getting lag or disconnection when there is a strong signal.

Any ideas?

I have several schools we run an after school program with some are hard wired the others have Hotspots with VOIP phones. Anyhow the end user is using tablets or laptops. I need to setup the Hotspot and router but was looking for any ideas on spreading the signal? I was also considering some sort of Antennas?

 I'm unable to run wires, everything goes in our office and then from there. I need a stronger signal that can go 40-60 feet. I thought about using the hotspot and then using powerline to where the router will go? If that makes any sense. Hook the Hotspot to router, that will need a wire to get the router into the other room.

I have disabled the wireless on the hotspots so I can use my equipment. I have 2 schools I need to set this up at. I'm not sure what to buy or get yet? I'm going for a powerful router but to get from point A to B and then out to tablets. The kids could have 2-3 rooms to use.

Any ideas or anyone with experience that can suggest. I'll get Netgear 3200 unless someone has a better option. I wanted to get Ubiquiti's but I cant run a POE setup on the power adapters....

Any suggestions are greatly appreciated. I need to order equiptment soon... Thank You All...

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.

SonicWall TZ300

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 8.8.8.8. Pinging 8.8.8.8 fails, but something like 75.75.75.75 will work fine. I run a tracert to 8.8.8.8, 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 …

So I've got a wifi access point here that I am able to connect to with my Huawei Mate 20 Pro. But it seems like the phone is not always actually using the wifi to access the Internet!? I noticed this when I was unable to start Youtube (I've restricted its use to wifi). But if I'm in flight mode and then only enable wifi, it DOES use the access point to access the Internet ( > Youtube works). So why doesn't the phone do this with 4G enabled? Especially since I'm standing right new to the access point.

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.

Thanks.

Hi.

We want to use Radius for our iOs/Wifi BYOD wifi network, with AD username/password auth (not TLS device certificates).

I've got Server 2012 R2 installed with NPS up and running, but as iOS doesn't trust the builtin (server.domain.internal) certificate, it prompts the user to trust it. I'm trying to get it working without any cert prompt.

I've installed and generated our CA domain certificate and pushed that to the iPads via MDM, and I can see that appearing on the iPad. Because it's gone via MDM, it's already set to "Enable full trust for root certs" by default.

I've then generated a CA-signed cert for the NPS server and selected it within NPS > Network Policies > Constraints > Microsoft PEAP.

When you connect an iPad to the SSID, it prompts for credentials correctly then prompts to trust the NPS Cert - but it is signed by our CA which the iPad already
trusts.  Should it not just trust the NPS cert??  I've also added the NPS cert to the iPad, seen that it is "Trusted" as it has the root installed and trusted, but still it prompts when authenticating onto the SSID.

If I trust the cert, the iPad is authorised and both UniFi and Smoothwall see the iPad with username so Radius itself is working - it's just the iPad is always prompting to trust a cert?

I've also read that generating a CA-signed cert via IIS request doesn't work, so used OpenSSL to generate a CA and CA-signed cert but that combination throws an error in NPS log "The client could not be …

Hello
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
/Mats
