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.

I have a Cisco 2504 WLC with 2 AP's attached to it but each time there is a power outage for up to 15 minutes, the WLC resets to Jan 2000 making it impossible for the SSID to be broadcasted on the network. I have to set the date manually to restore normalcy. I tried pointing my domain controllers to act as NTP servers to the WLC but this issue still persist.

Added some public NTP servers, still same error as I am even unable to ping the servers from my WLC.
How do I setup NTP server on Cisco 2504 wireless controller?

How to enable jumbo frames on all the windows based computers using GPO?
I have many windows 7/8/10 machines joined with the domain.
I want to enable jumbo frames on all the computers without going to each location & manually enabling them.
I have windows 2012 R2 domain controller, MS exchange 2013, SQL in virtual environment & iSCSI enabled NAS. Have enabled jumbo frame at CISCO SG300 switch running at L2. No VLAN is configured.
CISCO RV042 doesn't have jumbo settings.
ALL the NIC are gigabit & I assume all support jumbo frames.  One 8 port switch is 100 Mbps & unmanaged.


Please guide.

My cable provider just sent me a new cable modem to keep up with Docsys 3.1 standard.  It is a Samsung GX-MC990CL.  The interface my cable provider gives to configure it is not the one that is built in to it.  It is truly pitiful.

I would like to access the GUI that is built-in to this modem.

Does anyone know how?

We have a client that has a HP Color LaserJet Pro MFP M477fnw that is experiencing intermittent issues with printer.  It is in a workgroup environment with two computers (Windows 10) using Defender.  (We have even turned the firewall completely off on one for s*$(@ and giggles.)  

They are both connected to it over the wired network.  It will work fine for a few hours then will show Printing on the printer screen and just hang (as will the print queue).  A reboot of the computers (as I have been told by the employees) will start it printing again (sometime).  We have done the following to solve it:

* Factory reset the settings on the printer
* Updated the firmware on the printer
* Replaced the network cable
* Completely uninstalled the drivers from the computer, rebooted, downloaded the latest drivers from the HP website, reinstalled the drivers, rebooted the computer again
* Verified all network settings on the printers
* Confirmed static IP on printer outside of the DHCP range

This printer was bought new a couple of years ago and after all this troubleshooting and best practice steps taken to resolve the issue I don't know what to do.

Have the following:

Edgemax with Subnet of 10.0.10.0
USG with subnet of 10.0.1.0
I am trying to create a site to site VPN, but I am not very familiar with Ubiquiti hardware.

Followed the WIllie Howe video online, and I'm sure the addresses are correct, and I also checked the Ubiquiti KB page, and as far as I can tell, I have the correct settings, but no tunnel is made.

See the attached pics for set up.  

For the Edgemax, the local ip is what the external internet address is.  And the Peer is set to the USG external Internet address.
For the USG, the Peer and local WAN IP are reversed from what the Edgemax is set to.

I have also included the Edgemax firewall rules that I have added, but I have not made any rules on the USG yet as I am not sure what to add.

Any help is greatly appreciated.

No matter what router I use, I only get 30 - 50% of the internet speed through it.

If I connect a laptop directly to the Comcast modem, which is in "Bridge mode" so that the connected device gets a public IP address via DHCP, I get about 100mbps.  If I connect a router BETWEEN the modem and the laptop, the speed falls to 30-50.  There is NO OTHER device connected to the router or the modem.  I have confirmed this problem using a SonicWall TZ400, a Cisco RV180, an ASUS RT-N12, and a UTT ER518.  The issue remains for each of those routers.  I also used the same patch cables for each measurement.  Wireless is not involved.  

Why does this happen and how do I change it?

I just purchased a Siemon 10g ip 24 port patch panel and mounted it in my house for a home lab. I punched down my first port last night but something strange is happening. Right now I just have the cable coming directly from a laptop NIC to a punched down port on the Siemon 10g ip. The CAT 6E cable I made myself using the T-568B configuration. While this is my first patch panel punchdown, I have created a lot of cables in the past, using this same exact roll of 6E, so I am fairly sure my wiring is correct. I then have another cable going from the patch panel port to my Cisco SG300 switch. Now the problem is that I have no light on the SG300 switch port. I have 20 other devices working fine on the switch. I thought I wired it wrong but I re-wired the cable 3 times. The strange thing is that the laptop has full connectivity with lights on the laptop NIC. When I plug a cable into the laptop and plug directly into the switch I get lights on the switch port. I have tried multiple cables and multiple ports with the same result. When I unplug the cable coming out of the switch that is coming from the patch panel and insert it into a cable tester I don't get any lights on the cable tester check. Nothing whatsoever. without the patch panel the cable tester works fine. What could be wrong? Why do I have connectivity just no light on the switch? Why is the cable tester not showing me the wire checks? I have asked several network people and they have no idea. Did I purchase the wrong …

I recently purchased an Ubiquiti EdgeRouterX for home use. I would like to have my cable modem (192.168.0.1) plug into Eth0/POE in. I would like Eth1 to plug into my existing router (10.0.0.1) for normal filtered family access and WiFi. Eth2 would be used for a direct link to my SOHO office computer running Win 10 and defender. The Eth4/POE out would go to a POE wireless (Ubiquiti) device for business WiFi computer access and cell phone access, How would I segment these ports so they are not on the same network yet receive the signal from the source cable modem?

I know nothing about fiber and sfp connections.  I have a 10/100 media converters and unifi switches. (previous switches didn't have sfps) I have checked sfp's with known cables and all is good there.  But none of the cables I have tried, all of which Altex has said should work, show any sign of.life.  no indicators flash Nada.  I have tried too spend and wave length cables.  I have tried switching cables. no have gotten an rx failure, but that is it.

any ideas?

I have a HP Proliant N36L running WIndows 2012 R2 currently with an intel proliant pro/1000 NIC, acting as a repository for Veeam Backup copies running at a remote site. Since Xmas as soon as it starts to process our large copies (500mb or more) it BSOD with a memory corruption. Smaller backup copies work absolutely fine.
When it started all investigation was pointing to the onboard Broadcomm NIC which has been disabled & replace with the Intel Pro. Driver are as up to date as I can get them

I bought Windows 7 Professional and Deleted Windows 10 on a new laptop. Now the usb nor the network card will not work. They all give code 28 (the driver can't be found). THE CD/DVD drive works. Do I need to find drivers and burn them to a CD? Any help would be greatly appreciated.

I had this question after viewing accessibility for a client.

I am starting off with a headset with two male connections (one for audio, one for mic) that plugs into a windows 10 laptop. I connect wifi to a residential connection. My family member who has hearing issues can not be present to test often. Right now I am not interested in security so firewall is not important.

Hello,

I have a server with W2k16 running in RDS mode. To this server are connected 9 RDS user.

The main problem is the RDS client map printer from local computer to RDS enviorement, but for some reason, when a user ends session, and start session again, the default printers doen`t work.

It seems the system take an inactive TSport for the printer. i must configure the printers every time the user start session.

Is there any kind of solution here?


Thx.

Hi all,

I've been trying to access our Cisco SG300 via URL and putty and no luck. The switch is fine and running. I've been wanting to go in and bring a port alive.

Earlier, for the first time in weeks the GUI loaded via URL on the browser so I tried to log on and it wasn't doing anything. Also tried HTTPS and nothing (GUI.PNG) also I exit browser and reload it says... Unable to connect, etc on most browsers(cisco_browsers.png)

I also tried console access with PUTTY.
SG300 -> male to male serial cable-> DB9 to USB cable. Device manager shows COM4 so I set that into putty.

Connect to: COM4
Speed: 115200  (have tried 9600)
Data Bits: 8
Stop Bits: 1
Parity: NONE
Flow Control: NONE

SSH and Telnet was also not working.

SSH- file attached (cisco_putty_ssh) ...  "Disconnected: No supported authentication methods available (server sent: public key)

Telnet- file attached (cisco_putty_telnet) ... "Network error: Software caused connection abort"


I've completely rebooted my laptop and the SG300 switch as well.

Hello,

We have a single catalyst 4500 in our datacenter. It's a WS-C4507R+E with an ipbase license. It has
2x48 10/100/1000BaseT Premium POE blades,
2x4 Supervisor 10GE (SFP+), 1000BaseX (SFP) blades in active & standby hot,
1x12 1000BaseX (SFP) blade and
1x12 10GE (SFP+) blade.

In the interest of replacing this EOL switch, I am looking for a replacement which will last 10-15 years which can easily handle this environment with the possibility of growth and scalability to accommodate modern servers coming with 10GE NICs. I'm also interested in having it in HA mode.

We also have 2960S in stacked an unstacked modes connected to this 4500 via fiber. What can be a good replacement for them also?

Thank you.

I have been trying to work with Sonicwall support on this issue and have made no progress.  We have been using the appliance in the past with split tunnel enabled but, due to security requirements, we can no longer allow split tunnel.  If we turn it off,  remote users can access internal resources we have configured, but cannot access anything on the Internet. It seems that we need to create a resource which is "anything" on the Internet but we don't know how to do that. We don't see any kind of wild card options.  We have not given our users access to "Any" resource.  We need to specifically define the resource they have access to.  We need an "Internet" resource and then we can give them access to that.  Is this possible.  Or, is there some other way to approach this?

Sonicwall support had us upgrade the firmware to 11.40-468 with the 708 hotfixes but that did not create an options for resolving this requirement.
