Networking Hardware-Other





Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

My Surface Pro is connected to the internet through its ethernet adapter.  After that connection sits for a while the ethernet adapter is disabled and a wifi connection is made.  I want to stay connected to the ethernet adapter at all times unless there is not ethernet available.  Where there is no wired connection then the usage of wifi is perfect.

I would appreciate help in stopping the machine from disabling the ethernet adapter and in setting up the configuration I have in mind.

The machine operates on Windows 10 and all updates have been run

In my research, I saw a reference to an adapter troubleshooter.  It yields nothing.  I have also found references to a power adjustment tab for the adapter, in the Device Manager, through the properties selection there, I have no such tab.

We have a conference phone that needs to be moved around constantly where there is no ethernet jack.  Since our conference phone is a "wire only" phone, is it possible to locate a wireless hub that will connect to our router and then plug directly into the conference phone via an ethernet port?

Does such a thing exist and what's it called?
Hi guys,
I found this switch that will be potential candidate for my lab.
can you give me confirmation on the technical details?

24 rj45 Port Giga Ethernet ?
4 SFP (not SFP+) port ?
Possibility to add 2 modules of 2 SFP+ 10GB port each?
Layer 3 routing?

I don't understand what type of pci-e card + sfp module I need for my server or workstation
I am trying to implement TACACS GUI in my network.  First switch is a juniper ex2200.

Here is the juniper config:

tacplus-server { {
            port 49;
            secret "$9$QER439t1IcMLNHqT36/0OxNds4ZJU23DC1"; ## SECRET-DATA
            timeout 5;
    tacplus-options {
        service-name junos-exec;
    accounting {
        events [ login change-log interactive-commands ];
        destination {
            tacplus {
                server {
                        port 49;
                        secret "$9$DfHm5n6AIhr24UHqJ3s13333s"; ## SECRET-D                                                                             ATA
                        timeout 5;

    login {
        class Remote-Admin {
            idle-timeout 5;
            permissions all;
etc.... (for other user groups)

Open in new window

I have added the switch to the TACACSGUI Devices. I added a test user with corresponding service, and user group.  I have opened up all ICMP traffic between server and switch.  So, they can both ping each other.    When I try to login to the switch as the test user, access denied.  Nothing gets logged in the GUI.  Any next troubleshooting steps?
Customer looking for WAN optimization. I’m struggling to find appropriate options, as it appears Cisco is ending their WAAS options. The customer mentioned Riverbed, but indicated it was likely too expensive…

The customer isn’t technical, so wasn’t too helpful on the discovery call, but I gathered the following:

•      They have three Ethernet (L2) circuits into their primary location in CA.
•      They sounded like E-Line/ELAN, but…
•      150M, 100M, 20M (being replaced with a 600M down/35M up) – so, the latter is obviously broadband/DIA
•      They couldn’t identify how the Internet connection is being firewalled
•      They have a Mushroom Networks (never heard of it) consolidating these links, somehow providing an SD-WAN policy for them.
•      Nothing (according to them) is being encrypted.

So, all of that wildness aside, they’re looking for something to front these appliances to accelerate their throughput. I’m open to a solution to optimize over each of three links or something larger, such as an SD-WAN option to bring all of them into a policy, etc.
I need a Wireless Label Printer, with WPS


I am okay using a thermal printer, which requires me to buy rolls of thermal paper.

I need it Wireless and I need a WPS button..

Does this printer connect easily to my WiFi?

Without having a server I have a program with 4 licenses that I want to be able to work on host computer and also on employees computer that is offsite.  I know this should be possibe.  Which is the best way to configure this?
Gloria in Oklahoma, US
I need to set up a site to site VPN, to allow a client to back up his office computers to a NAS in his home, across the Internet.  We haven’t purchased the NAS, nor routers, yet.  I’m looking for a recommendation for the brand, and even the model, of router, or routers (or firewalls) I’d need to accomplish this.  I know that some NAS-es feature a VPN server (QNAP does, anyway,) but I’m not clear that it would be appropriate for a site to site always-on VPN.  Please address this topic, too.  Thanks!
I am new to Ubiquiti. On a previous installation, I used a Windows computer to set up the UniFi Controller.

Can this device replace the need to set up a Windows computer?  It is certainly more compact.

I have a Nexus 6k connecting to UCS Fabric Interconnect. What's puzzling to me is that there are are "jumbo packet" - millions of them counted in the sho interface commands. But the MTU on the Nexus side is 1500. And the same thing is true if I log onto the FI - I see jumbo packet counters highly incremented and yet the interfaces are all set to 1500 MTU. Any thought as to how I could be seeing these big counts of jumbo "packets" (Frames would have been a better term no?) when I don't think I have jumbo framing configured on either side of these links?

Hi Guys,
can you recommend a very cheap/refurbished VDSL2 modem ONLY with rj11 (POTS) WAN connection?
I want only modem or bridge feature because I have a dedicate firewall.

For now i have seen Draytek Vigor 130
Hi Guys,
My connection is FTTC VDSL2 and in arrives fisically from the wall with rj11 cable.
I want to set a VM PFsense for firewall and vpn purposes.
I figured that the fisical architecture is follow


-VDSL2 Modem must be set on Bridging mode
-Firewall WAN port must be configure (PPPoE, username and password ecc..)

It's correct?

We recently purchased an EMC ME4024. I have tried several SFP+ transceivers and DAC Twinax SFP+ transceivers to no avail. The device GUI notes they are incompatible when inserted. Can anyone direct me to the correct transceivers to drop in this thing? Maybe something I can go straight to Amazon to purchase. Thank you in advance!!

Btw, I'm connecting it to the switch below for iSCSI config to 2  PE-640 Server 2016 hosts (Qlogic SFP+ network controllers).
MikroTik 5-Port Desktop Switch, 1 Gigabit Ethernet Port, 4 SFP+ 10Gbps Ports (CRS305-1G-4S+IN)
I'm trying to setup a single R610 Zoneflex wireless AP to have 2 networks, one that has internet access only and another that has internet and office resource access.  This is going to be used at a skating rink where our members will be accessing the internet only and our staff both.
I'm new to ruckus devices, but I have setup Unifi and other devices.

Any suggestions on how to configure this properly?
Seeking information from Australian IT Pro's

A stalemate with the Internet provider and their supplied router has me stuck.

We needed to add an additional port fwd rule to the device a Telstra V7610 (we have 4 at present) and when added it fails to fwd the 5th port.  The Internet Provider confirmed it was an issue and has:
  • Downgraded the firmware and it failed to rectify.
  • Sent a Technician to our site to repeat the process and confirm I am seeting it up right, and was able to confirm that it fails.
  • Upgraded the firmware to a yet to be released version which created its own new list of problems, one of which was the loss of access to the management interface as soon as the connection to the NBN was online.

Like many we had to remove a perfectly good apliance (Draytek Vigor Series) and replace it with the Telstra/Netgear V7610.  In two years we've had the V7610 replaced 3 maybe 4 times to address problems with DOT and connection quality.

Do you have a solution to retianing the V7610 for DOT and another device for all other services, even better do you have one that addresses a V7610 with a Draytek Vigor appliance?
I am using the Juniper migration tool but is this the best method when you are changing vendors from Cisco to Juniper as it relates to access switches. I need to be 100% accurate with the configs . Any suggestions much appreciated.

I am setting up a SOHO.
Equipment is as follows.
1)  4 security cameras that record to the cloud through a Northern system
2)  Home wireless system mesh network
3)  Usual computers,  printers, etc
4)  Other "internet of things devices"  such as thermostats, lights.
5)  I have a total of 10 Ethernet jacks in our home, but only 6 in current use.

I will be installing a 19 inch 6U Wall Mount Patch Panel Bracket - 13.75 inch deep (also 24 port Cat 5E patch panel etc)
Gigabit internet.

I have concerns about putting all these things on one switch.  I like the idea of segmenting my network.  
I have heard good things about the Ubiquiti.  I am not an expert on routers, but I not a unfamiliar either.  
I am thinking about a router/switch capable of VLANS and POE for the cameras.  If I am misguided, then new insights are welcome.

With that in mind,  I would appreciate any help in selecting  a router / switch that would be appropriate but not more expensive than I need.

Thank you for your help.
I'm thinking about using Companionlink to sync my Outlook to my Android phone.

Have used it in the past.

Looking at connecting via Bluetooth as it's the simplest option.

Concerned about security.  

Seems like the software sends data via Bluetooth encrypted.  So, checks one box.

Here's my question - after I get the phone and the PC paired I can turn off discoverability.  But...seems like, for my Win10 PC (and lots of others) turning off Bluetooth is not enough.  I've got to run services.msc to get discoverability  ACTUALLY turned off.

So, my question is: am I on the right track here: to ACTUALLY keep my PC undiscoverable I would have to run services.msc and disable it at that level?

Then, to the base of my question: somehow having my Outlook data transferred via Bluetooth is dismaying.  Should I have that concern?  

My other options used to date have been using MS Exchange locally via a program called Akruto.  Or, using Companionlink over Wifi.  Each of these are also locally broadcasting my Outlook data to my phone.  (At one point I was even super secure syncing with Companionlink via USB cable.  Safe, but not efficient.)

So, my thinking now is this - if I can get Bluetooth discoverability ACTUALLY disabled on my PC and my phone that would reduce the chance when I'm on the road for a malefactor …
Dear Experts
We are evaluating CCTV surveillance system appox 25 to 30 cameras which should store 03 months of recording hence NVR hard disk capacity we have sized 6 TB.  We have connected this location over MPLS link to the Head office hence we are thinking to look for solution but not sure at camera side or NVR side the recording to happen parallel to NVR and also to NAS device and this NAS device will replicate to another identical NAS device over MPLS link at head office
1.Please help is there any specific type of cameras OR NVR we should consider so that at the same time two places the recording is done one at NVR disks this is going to rotate once in month hence at any given time only last 30 days recording is available.
2.Also simultaneous recording in additional to NVR to store to NAS box for example synology NAS box ( one at site and another one in head office every day replication scheduled to head office)
I have ordered 1 GB internet service (BW) hand off from Bell. The firewall will be the gateway for 5 offices with total 200 users. I would like to install CISCO ASA 5500 series as internet gateway. ASA will have VPN to AZZURE as well for AD and SQL sync. Can you suggest the ASA model best fit for us? Current firewall is 5508 X which handles 1 office (40 users) and 200 GB hand off but we are upgrading the circuit to 1 GB and adding 4 more offices (total of 200 users).
Customer is connected to their DC via Internet. Is there a way we can support WAN Acceleration over Internet to their cloud? We are looking for a way to support Acceleration ,if it can be. Riverbed Steelheads can be supported for Both POP and Customer DC.

I have Nec ITX-3370-1W(BK)TEL POE phone and when I attached it to Cisco 3750 POE switch the phone not working while when I attached Nortel 1120E or 1140E they are working.

Any idea to fix the problem?

I'm experiencing a Linux routing problem.

Environment is SLES 12 SP2, running on some HP server machine with 8 physical, used network interfaces, running in a non-internet local network.

Most physical network interfaces (eth0 ... eth3 and eth5 ... eth7) have (local unique) static IP addresses in non-overlapping networks, and the routing table looks ok. The interface eth4 is on DHCP.

The problem is that sometimes packets seem to be sent over the wrong interface - a packet that is expected to fly thru eth6 is spit out on eth0. This happens erratic and causes to application software (managing measurement data) to loose the data stream after max ~15 minutes .

As fa s I can see,

  • the exit interface of the wrong-routed packets is always eth0
  • there are packets of at least 2 interfaces routed wrong
  • the configuration of eth0 (viewed by YaST and by inspection of /etc/sysconfig/network/ifcfg-eth0) shows no IP addresses from the other interfaces networks

If I take down eth0, the application runs smooth (but that's only acceptable for testing matters).

If I record the network traffic of the network addresses for eth2 (tcpdump), I find i.e. suspicious ARP requests originating from address on eth6 with an originating MAC address of eth0.

Any idea what happens here ?
Any idea how to fix it ?

P.S.: Due to some policies demands, I can't do any driver etc. updates on the system. Same appies to ideas like "do DHCP on all interfaces" ... I can't change that.
So we have a bunch of Aruba 215 access points running with a virtual controller.

I have set up a radius server and from the CLI i can successfully authenticate

aaa test-server ISE-01 username password <password> auth-type pap
Radius server ISE-01 test successfully

on the Radius "ISE" server i see

Event	5200 Authentication succeeded
Endpoint Id	A8:BD:27:CF:3B:8E 
Endpoint Profile	HP-Device
Authentication Policy	Default >> Default
Authorization Policy	Default >> Basic_Authenticated_Access

Open in new window

However when i assign these radius server to a SSID and try to authenticate a client it gets

Event	5400 Authentication failed
Endpoint Id	A4:50:46:1F:13:33 
Endpoint Profile	
Authentication Policy	Wireless_POC >> Default
Authorization Policy	Wireless_POC

Open in new window

where did the USername go? This same set up on ISE works fine with the Meraki wireless but Aruba is having issues.

HAs any one else has issues trying to run PEAP and EAP-TLS on Aruba wireless over 802.1x

Our company internet provider set us up with a new modem which would deliver faster speeds and has the IBGP failover ability. In order to use the IBGP failover we would need to designate 1 (or 2?) IP's from our small block of IP's, or get rid of the current ones and use a larger block of IP's.

Does it make sense to just consolidate our current IP's instead of purchasing a larger block of IP's? We currently have 5 public (outside of the broadcast)

Is it best practice/ industry standard to purchase larger amount of public IP's?

Thank you.
