When I try to FAX from my PC using the Epson FAX Utility in Windows 10, I hear the phone go busy before the FAX number is finished dialing.

Conversely, I can FAX from the Epson WF-4630 control panel just fine.

This is my home office & the printer is connected via the network. I run the FAX utility "Check FAX Connection" & it shows everything is fine. Unchecking "Dial Tone Detection" doesn't seem to do anything. Epson software update doesn't show any updates other than the unrelated "Epson Connect", "E-Web Print".

The phone line is VOIP (T-Mobile Line Link) & I don't need to dial anything to get out.

I am confused why FAX from the printer would work but not the Windows software. They both use the same settings.

Question on a fiber setup.
Fibre Infrastructure (see attached pictures):
    Approx 200 Meters of 9/125 Singlemode duplex fiber optic cable, running between two building.
      Each end runs to a Planet GT-802(V3) Gigabyte Ethernet bridge.
        The Planet Ethernet bridge is then patched into GByte network switch using a cat5e cable.

        Problem:
        The gigibyte network switch is detecting the fibre connection as 100mbs - not 1Gbs
        I have replaced the cate5e cable. and tried patching the cat5e cable into another 1Gbs switch.

        I don't have much experience with fibre Infrastructure, but I'm looking to understand what next steps should be to troubleshoot this issue.

        I bought a netgear CM 400 cable modem a couple months ago. It has 1.1.13 firmware on it.  It was working fine for a couple months and now I am getting a bunch of errors / internet drops out.

        I see from this page

        https://kb.netgear.com/000036375/What-s-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router

         that the latest firmware is 1.1.17 - 19 depending on the ISP (I am using optimum / cablevision in New york which isn't on the list).

        I called netgear and cablevision >>executive<< office and got the same answers - the firmware has to be updated from the other.  Neither offers updates for this modem.  And yes, I tried the Cablevision tech department then called the executive offices and they supposedly took a day to do checking with the topmost people to get the answer 'you have to go back to the manufacturer - we don't update modems other than the ones we supply).

        I put a cablevision rented modem in place (a different brand - arris) and the errors / lost internet went away. Not sure if the modem has a hardware problem or newer firmware would help.  I really don't want to pay $10 / month to rent a modem.

        Any idea how to get it to the newer firmware?  Anyone know where to get the changelog for the firmware to see if the newer versions might improve the situation?  Or if I buy another CM400, how to tell from the label what firmware is on it?

        Sites hosted on godaddys secureserver.net are inaccessible from our main external ip address.  I called our firewall support at sophos and they said that the sites in question are not responding to our tcp handshake and this is why we cant connect. Sophos says I needed to call godaddy and see why they are blocking our ip address. I called them but they said our ip is not blocked and there is nothing they can do for us.  Im not sure what to do next.  Any ideas?

        Building a new server room.  What are the opinions to go with CAT6 vs CAT6A.
        Heard A its more expensive than regular 6 and more difficult to use in the field due to the jacket thickness.

        Please advice.
        Thanks.

        I tried to google around to get some answers for two cisco switches connected by two stacking modules. some people says each switch should have one uplink, two stacked switches should have total two uplinks,  however, some other people says two switches only need one uplinks. what is the correct answer?

        This question might be very simple for some network engineers,  I am not that professional, but happen to have the need to setup a security camera system.

        Please refer to the attached simple chart. I am trying to setup a small security camera system with 16 POE cameras. I decide to use Cisco 2960x-24PSQ due to its fanless, low heat feature. however, each switch only has 8 POE port though they have total 24 ports each, so I have to use two exact same switches for 16 POE cameras. I assume both switches need to be plugged into the router such that each camera can get their individual ip address?

        My question is: where would the Storage server will be plugged into? the router? or either of the two switches?  as far as I know, the router normally don't have many Ethernet LAN port, maybe I should insert the third small switch between  the router and those two Cisco switches such that two 2960x, storage server can all be plugged into this third switch, this third switch then  turn around to plug into the router? is this third switch necessary ? or any router model can do the job without adding the third switch?

        thanks for any comment.

        In the specs saying :
        APC Smart-UPS SRT 5000VA RM 208V to 120V 2U Step-Down Transformer

        Does that mean it has 208V input and 120V output.  Or I can plug it in either into 120V or 208V?  
        Do I need to have 208V 30Amp plug for this?

        Please provide me with the part number for a regular SonicwALL TZ600 firewall.

        While looking at ads for a lower priced "SonicWALL | 01-SSC-0220 | SonicWALL TZ600 High Availability Unit 01-SSC-0220 TZ-600" it is noted that this product "Must be paired with a regular SonicwALL TZ600 firewall."

        What about the Junipers?  
        Any good opinions?

        I am new to using Verizon FIOS. It is not available in my area, but a client of mine built a new house where it is available, and advised that they had the network wiring under control with a local installer.

        Now the house has about 15 STB wall ports -  each with an IP address on the Verizon router.

        My question is: Can these be used as the ethernet cabling (when not used for a set top box)... or are they strictly for set top boxes?

        Thanks for any info. Not having seen FIOS before I am confused.

        Hi

        2x 2920 Core switches with 2x HP Edge switches connecting

        If you have a stacked pair of switches (so 2x HP Procurve 2920 connected in a ring configuration with stacking cables) - then how should trunks be configured (etherchannels for the non HP switch aware) to access switches?

        If I go to the Menu CLI and it lists the ports of both switches, I assume that if I setup a trunk on ports 23 and 24 on switch 1 then I need to setup the same on switch 2.  

        - Do I set these up as two trunks with 2 ports from each switch contributing?  (ie - Trunk 1 with ports from Switch 1 ports 21,22 and Switch 2 ports 21,22, Trunk 2 with ports from Switch 1 ports 23,24 and Trunk 2 with ports from Switch 2 ports 23,24
        - Or do I set them up as four trunks? (Ie Trunk 1 with ports from Switch 1 ports 21,22, Trunk 2 with ports from Switch 1 ports 23,24, Trunk 3 with ports from Switch 2 ports 21,22, Trunk 4 with ports from Switch 2 ports 23,24)

        Hopefully makes sense  - I have tested it with option 1 above and fails over without issue but just wanted to confirm the best practice

        Thanks

        if you replicate data between your primary SAN to a DR SAN, what assurances and checks need to be performed to verify the health/reliability of the link between the sites and the replication process? What risks are there with such a setup, and what best practices/monitoring need to be in place to minimise those risks? what evidence could be requested to verify these risks are well managed with best practices?

        I am running sql server 2008 R2. Everything seems to be running just fine.  The server is running on Scale hyperconverged servers.
        When I try to run the report from my own desktop using studio management, or even when I RDP into the server, it does not work.
        The report is called  "all blocking transactions".
        Here is the error message.
        sql error
        When I log into the server directly via the console, the report works fine.   All other reports work just fine from my own desktop or even via RDP, it's just the one called "all blocking transactions" that does not work.

        Any idea's if this is a sql issue or some kind of network problem, but I doubt it's a network issue, as all other reports are running just fine.

        My 10yr old Netgear WNR3500 seems too old and only giving up to 10Mb with our new equipment.  
        Its RangeMax wireless-N Gigabit router.  Been good for us but.. for the last few years with newest devices seems compatibility issues there.

        Should we stay with Netgear and get the latest model or some other good options around there?
        Thanks.

        I was experiencing significant interference and resulting wifi issues connecting a Lenovo Yoga 910 (which has limited USB ports) to my wifi network at 2.4 mhz.  I was using an USB 7 port hub which was adding to the problem.  I switched renamed the default network SSIDs which were the same at 2.4 and 5, then connected via the 5 mhz band and everything starting working very well with one exception.  My HP 8610 officejet printer operates solely at 2.4 mhz and I cannot figure out how to print (transmit the signals) from my laptop operating at 5 mhz to the printer wirelessly.

        Can this be done and how?

        Thank you for your assistance.

        Have a environment where I want to restrict internet to all computers except of 2.
        Looking for a router that instead of blocking the once I want to restrict I should be able to block all and allow the the few I want to allow (a ip range)
        Not a big network no fancy router simple
        it's about 25 devices all have a static ip configured on the device

        I'm trying to add routing port (fa) but it only allows me to add switching port.  When I add switching port it does not allow me to configure it with an IP.  I'm trying to add it on router 1841.  Thanks in advance.
