Wireless 802.11n Wireless Lan Card

I want to use the built-in NIC card and hard-wire this computer to the internet, but there are no lights when various cables LAN cables are plugged in.  I have tested the cables and the switch connection and everything seems to be fine.  There are no errors in the Device Manager.

What could be happening?  How can I best hard-wire this computer?

Assistance is greatly appreciated.

I want to buy a 1M FlexStack Cable for my 2960s switches, but I can’t see the part number (CAB-STK-E-1M) for price estimation in CCW.
Any advice why

NETGEAR CM500-1AZNAS (16x4) DOCSIS 3.0 Cable Modem only provides 38Mbps vs. cable modem's 150Mbps. Specs for the Netgear say up to 620Mbps.  The upload speed is 5.7 which equals the cable modem.  There are no adjustments in the modem.

I have a data jack that is terminated; but, not properly labelled.  I am trying to use a tone generator to find the correct patch panel connection that I need to use and cross connect the ethernet correctly to the end point.

https://www.youtube.com/watch?v=JHRIiw3OR6Y

The problem is that this specific data jack is in a machine shop floor and when I activate the toner every patch panel connection is triggered in the room.  If I turn off the toner generator every patch panel is still sounding off in that room.

If I try the toner generator in different locations(other rooms) there is no problem.  The toner generator works as I expect it to.

What could be causing the toner tester to sound off in that 1 specific patch panel?  Could it be that the ethernet cables were not grounded correctly?

Need to block network users from being able to access BitTorrent (BMTORRENT).   I have a Sonicwall TZ-215 along with the premium content filtering.  I can block the URL of the usage, but can not determined the proper ports to target the service to block.  

Goal is to not have to upgrade to the "Application Control" that can detect the signature of the traffic or such.  I am fine with blocking the defaults or making more difficult for the person.  I understand that they could use other methods to avoid detection.

https://www.experts-exchange.com/questions/29118598/VONETS-VAR11N-manual-driver-functionality.html

Just received the Vonets device & tried the above suggestion of setting it to "Bridge + Wifi repeater"
followed by steps in page 7 & 8 below:
https://www.manualslib.com/manual/1044556/Vonets-Var11n-300.html?page=7#manual
https://www.manualslib.com/manual/1044556/Vonets-Var11n-300.html?page=8#manual

Q1:
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.

Q2:
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

Have a client where the building power isn't that stable. Done everything we can to have maintenance clean up the power issue. Meanwhile two UPS went out at the same time which to me means a surge happened. Simple question, what do ya'll recommend for a medium business running a PowerEdge Server, 2012 Server Storage, three switches, phone system, and two workstations. This is the server room and not the entire business - FYI.

I need to provide a summary if there is any risk in the following 'practice'. We have a number of users who leave there desktop PC's running overnight in an office environment. They are always locked, but seem to be too lazy to actually shut the device down for some reason. The high level of management are aware of this but seem of the opinion 'so what'. I am not sure there any real obvious security issues so long as its been locked, except perhaps disclosing the officers logon name., I'm hoping there are some other issues which have perhaps been overlooked that can build our case to issue disciplinary action against staff for doing this kind of sloppy behavior.

We have 2 x Aruba 7030 hardware appliance controllers that we want to use as local controllers for our Aruba Wireless system.  Another administrator setup:

2 x Virtual Master Controllers.
2 x hardware 7030 controllers.
1 x specific VLan IP Subnet where there Hardware local controllers reside on with the Wireless Access Points.

Both Aruba hardware appliances are in 'Standalone' mode. We wish to change the mode from 'standalone' to 'local'.

My question is how can I change the mode of the hardware controllers from 'Standalone' mode to 'Local' mode?  I hope I do not need to reset the controllers to factory default settings.  

I have found a web site ( https://community.arubanetworks.com/t5/Wireless-Access/change-controller-role-from-standalone-to-local/td-p/279521 ) that states

"... You should only have to add it as a local controller to the master via cli
 
>masterip <ipaddr> ipsec <key>  ..."

Since, I have never done this before I just want to make sure that I understand what needs to be done.  Hopefully, I can communicate with someone that has actually done this before.    My understanding from the above web site is:

1.  You can change the mode of a controller without re-setting it to factory default settings.

2.  Login to the hardware local controller and from the C.L.I. >masterip <IPaddress> ipsec <preshared key><enter>

3.   The IP address that must be entered is of the Master Mobility controller; but, what if you have 2 master mobility …

I am using a QNAP TS-859U-RP NAS as the backup destination for my server. This NAS is running firmware version 4.2.6 (which is the most current firmware version for this model).

This NAS is used for about 90 minutes each day during the daily server backups.

I would like to find an automated way of setting this NAS to power on and power off at certain times each day so the backup jobs can be written to it and then when it is no longer needed the NAS will power off.

Is there any way of doing this?

My ISP is Comcast and I am assigned a range of 5 external IP addresses.

How can I determine which external IP address the SonicWALL VPN is using so that when I configure the VPN clients on Windows 10 computers I will put in the right external IP address?

The SonicWALL router is a TZ600.

What are the steps to lookup the SonicWALL VPN domain name?

This "domain name" can be different than the Active Directory domain name and needs to be entered within the SonicWALL NetExtender VPN connector. Where within the SonicWALL configuration settings can I look up the "domain name"?

Hi Experts,

we have to plan a big move to another building.
I have some questions about it.
Our datacenter is using RJ45 patch panels and cabling is done with CAT7

The new building has older technology installed and another patch system , called SYSTIMAX.
This SYSTIMAX patch system is new for all of us and the installed cables are all CAT6.

What kind of patch systems do you use in your datacenter ?
Do I have so many benefits with SYSTIMAX ?

After this there is no more output on the console.
I looked at on of the Brocade SAN Health software reports and it showed a failed power supply fan.
We had a power failure due to which this switch got shutdown and has been in the above stated status since then.
Will it be the failed power supply causing this?
Is there a way to be 100% sure that this power supply is the cause of switch not booting up as then we can buy the power supply.
What else can cause this and what …

Dear Experts，

I have a set of fortigate firewall policies which I need to duplicate on a cisco router.

I have done most of the point A to point B.

The issue I have now is the NAT and there is an IP Pool, is there a guide on how I can translate the rules from firewall to cisco router?

Any help is appreciated.
