Vectra Subscriber: Cisco EPG3925 Modem, Public IP, Home Network Connectivity & HP C6280 Printer

Hi
Sorry for a stupid question, but no one has reported a similar problem here, but rather the other way around (no internet in a similar configuration - and I have internet)

I have been a subscriber of Vectra for several hours. I have a Cisco EPG3925 cable modem connected to a switch and my two computers and an HP C6280 network printer are connected to this switch (all wired). And I have public IP (because Vectra gives them to everyone).

Modem configured by the installer (in Vectra the user has no rights to change the modem configuration). TCP / IP properties on both computers set to automatically download settings, as instructed by Vectra. And on both computers the internet works OK, fast and completely flawless. However, they cannot see each other on the local network. Everyone in the network environment or workgroup sees only themselves. They also do not see the network printer.

The computers are of course in the same workgroup, and anyway, the home network previously worked properly under the previous provider (TPSA), with the same configuration (except that instead of a Cisco cable modem there was a Livebox dial-up modem; and I had no public IP in TPSA).

Can I ask for a hint what I am doing wrong and what needs to be done to make the local network work?

In tpsa, I had a public IP only that you were behind the router. And so you were on your own private subnet.
Probably you got (bought) 2 ip addresses from vectra (possibility of direct connection, without a router, 2 computers, each with its own external ip).

You need a router with an ethernet port. If you already have a connected switch, the router itself is plugged in between the modem and the switch. Since you have everything on the car and it works, there is a good chance that everything will start 'on the spot' on the default settings.
You just have to remember that you will be on your own subnet again, with an internal ip address. If you want to start any services (servers) that are to be visible outside - you have to remember to redirect the appropriate ports.

Hi

Thanks for the quick reply! And also:

About port forwarding on this router which will I buy? Because as I wrote, there is no possibility of redirecting ports by the user himself on the Vectra modem.

I think I can handle it, I used to redirect Livebox ports in order to use the p2p network. I think that it is done similarly in each such device?

Yes, on the router. The modem has nothing to do with it.

What is your computer operating system? Check if you can set up two IP addresses for your network adapter. Windows PRO version have this option. I do not know about the Home versions, because I am not dealing with them.
It's about something like this:
http://banita.pl/konf/siecwinvista.html
The computer card then has double IP addresses. One for Vectra (address, gateway, DNS), the other for LAN (no gateway, but shared address pool with the second computer and printer).
This is how you can settle the matter without investment.

I have Windows 8 in my and my brother's Windows XP and it's probably Professional, I think. So it looks like it would be possible! Thanks for the hint, it's actually very interesting, if you could, it would be great. The only thing is that these original Vectra settings, recommended by the operator, are based on the "Obtain this-and-this address automatically" principle. And it is allocated such a bizarre on the basis of 31.140.xxx.xxx, and on the second computer 178.232.xxx.xxx. Will it work properly in this case if I manually add a second address from the local pool 192.168.xxx.xxx.? Will they not "bite" with each other?

They won't bite. One address can be assigned automatically by DHCP, the rest can be added manually. There can only be one gateway to the Internet, but this is also automatically granted.
I am administering a network where some devices are in a different logical network, even though they are connected to the same switches. It makes our work easier because it is more logical. This way I have four IP addresses on my PC.

Okay. Although the problem has not been fully resolved yet, these tips helped me a lot. However, the situation is a bit different for me than you write:

Well, no, at least not for me, not for Win 8 and not for Win XP Pro (maybe Win Server does?). If "Obtain an IP address automatically" is selected for the connection in the first window of TCP / IP protocol properties settings, then after selecting the "Advanced" button, the option to add a new IP in the first tab is inactive ("gray"). But that's okay, I went around it as described in the link you gave me http://banita.pl/konf/siecwinvista.html. Ie.

- when set to "Obtain an IP address automatically" I noted this automatic address, subnet mask, default gateway (interestingly, there is a different gateway on both computers ) and DNS

- I switched to manual input of the IP address and entered the previously noted addresses, masks, etc. At this point, in the tab, the option to add a new IP has become active

- I added new IPs from the local pool on both computers, the same as they had in the past (192.168.1.10 and ... 12)

- according to the advice in the link from banity, I set "Enable NetBIOS over TCP / IP"

Well, like I said, partial success: computers can see the network printer, which was quite important. However, they still cannot see each other in the network environment or workgroup. Interestingly, they can successfully ping each other using local addresses. But they can't see each other.

What else am I doing wrong?

EDIT: It worked! I found such a tip somewhere on the network and typed something like this in the Run window: \\ 192.168.1.12 (this is the local address of my brother's computer). Well, all the resources previously shared on it appeared to my eyes It is true that some of them could not be opened, but the most important one was. I added a toto as a network place and did the same backwards on my brother's computer, adding my shared resources as network places.

Now I am tormented by such a doubt: Is all this available only in our local network and not in the public? can i check it somehow?

It is available in every network to which the computer is connected (it can be turned off for a specific network card, but not for the IP address) - if vectra does not cut network traffic, you can also see it from the outside.

Statically set addresses are a mean idea - if the DHCP lease expires and gives you a new address, your Internet will be dead (and you will have to do everything all over again). Unfortunately, it cannot be resolved otherwise.

Indeed, I was wrong - I did not fully check. When DHCP (automatic address retrieval) is on, addresses cannot be added manually. I set it manually, so I didn't come across it. Sorry.
You can leave it like you did. The problem may arise when DHCP Vectra tries to force these addresses to change periodically. I hope not.
Availability or not of individual resources (folders, files) is a matter of Windows permissions, not of the network.
The resources can theoretically be seen from the Internet, if only because you have public addresses. Here, adding private addresses does not change anything for you, because from the outside, public addresses are important). Computers have system firewalls or software firewalls (Zone Alarm, Norton or others), in which you can insert rules allowing from the LAN network (trusted zone) and blocking access from the Internet. But that's a bigger fairy tale. These firewalls are usually already properly configured in the company, but it's worth checking. The weakest one is the firewall in Windows XP. There is basically nothing to configure there.

Unfortunately, Vectra gives floating IPs and they just changed me. I set everything up again and it works again, but still ... every 24-48 hours I repeat such an activity, it gets a bit tedious in the long run. You can buy a permanent IP from them, or for a small fee. But I guess I will ultimately decide to buy a router due to the aforementioned doubts about sharing resources.
In the store on the estate, for PLN 72, there are the following: 8LEVEL WRT-150 and TP-LINK TL-WR340G, with the former they even write that it is recommended for Vectra (although it probably does not matter). Is there anything that I should pay special attention to when buying?

It is important that it has a WAN - Ethernet port. Not with the adsl modem (these are the most popular).

Hmm, that is, from the built-in router in the EP C. 3925 not possible to use?

Now that your modem works, don't touch it! Buy TP-LINK TL-WR340G (without modem), set the WAN to automatic address retrieval, and connect computers to the LAN.

Before making any purchases, call BOK (or what he assumed you were), present the problem and ask what's going on ...

The gateway has four Ethernet ports (your switch is not needed) and the first offer is where max. number of computers that can be connected by the customer = 4 is:

(I don't know if this agrees with your package)

what's going on with these addresses almost from space, I'm also curious:

This lack of permission to change the modem configuration is in order to block WiFi, which is additionally payable?

I did more or less. Only on the occasion of the star I bought a better one for the Christmas tree Cisco Linksys E2000. On the forums, I noticed that a lot of people wrote about problems with TP-Link in Vectra, I thought that maybe it's better another. And I wasn't sure if the 10/100 Mb router would not slow me down since the local network is 1 Gb; supposedly it only lets traffic outside, but on the other hand it assigns addresses locally. Well, I already took one with 10/100/1000 Mbps inputs in stock. I gave automatic settings download and everything works fine.

So I did; in general, the conclusion is that I can connect whatever I want, but I do not have the right to interfere with the modem (gate).

The switch would indeed be formally redundant; however, due to the layout of the apartment - the gate is in one room where the cable ends and computers in the other - it is most convenient not to change anything. In the days of TPSA, it was the most comfortable way: Livebox also supported their TV, so it was comfortable to stand close to the TV; and the LAN port basically had one. So I then ran the network cable from the computer room to it (the wireless connection went through two walls and was often broken). And of course I had to give the switch back then. Now going to Vectra I just took it out
this cable from Livebox and plugged into their gate.

Honestly, I do not know for what purpose, generally that subscribers do not fumble them (in my package WiFi is included in the price). In any case, the regulations clearly state that the modem remains the property of Vectra and the subscriber has no right to make any changes to the hardware or software configuration or anything in this sense. TPSA should be honored here, which does not make any difficulties with it, in Livebox the subscriber can mix at will, although with them the modem also formally remains the property of the operator.

I have a huge problem. Until recently, I had this: a modem from Vectra, a D-link router attached to it, a desktop computer to the router with a cable and a laptop via WiFi. I had a fixed IP assigned to the mac address of the router, I had a nice internal network and both computers on the net had a fixed IP.

Now I suck: a WiFi modem from Vectra, a desktop computer attached to it with a cable and a laptop via WiFi. The stationary has fixed IPs and the laptop has variables, and I can't create a network help, something can be done in the current hardware configuration so that both computers have a fixed IP and that they can be networked? ufff

Hello,
hooking up to the topic.
From today I am the owner of the vectra net and already the first surprise. The wi-fi modem they gave me only allows two places on the WIFI network ?! I have two landlines plus a laptop on the way and one is short of space. Hence the question whether I can buy any WIFI router and connect it to the LAN to Vectrowski and everything will be ok?
Thanks

Hi

For the sake of order, and because I was encouraged by the forum bot, I would like to add that I managed then, two years ago, not so much to solve but to work around the problem I wrote about. By adding my own router to the Vectra modem, I was able to freely configure my home network so that the computers could see each other.
