29.09.2021 Jan R. (Hammoor, Germany) Networking between 2 buildings. Forwarding of a fibre optic connection (600/300 Mbit/s) via telephone cable.

Good morning, I had read the reviews on Amazon, but I still didn't think it would work sooo well! Thank you very much, everything problem-free! Great product and great service!!!

12.09.2021 Dr. Thomas S. (Aachen, Germany) Networking in the house and between 2 buildings

Perfect network connection via COAX cable.
When we renovated our listed house a good 25 years ago, we installed a well-equipped COAX and telephone network, but did not consider LAN. In addition to a COAX cable for the later (never implemented) cascaded SAT connection, we laid a "replacement" COAX, Phone and NYM 5x2.5 cable for later use as an underground cable to the similarly equipped outbuilding about 50 m away as an island solution. Now a solar system installed on the roof of the outbuilding required a LAN connection to the main building. I remembered the unused NYM cable and installed dLan. Despite high-quality DINrail equipment, I only achieved rates of 50 / 20 MHz with an inconstant connection. Asked Google for alternatives -> found GIGACopper.
Of course I was not very optimistic about COAX / Tel data transmission. But it was worth a try, especially as the costs were manageable. I was most confident about the physically "thick" KOAX cable, the Tel cable less so. Two COAX G4204C adapters, configured as master and client, arrived super-fast when I ordered them from GIGA's HP. Self-explanatory, the connection was made in a few minutes and I immediately had a data rate of approx. 1500/1500 MHZ in the neighbouring building via my "reserve" ground COAX cable. I did not want to believe it at first. I then disconnected the dLan slave in the neighbouring building (Wlan adapter 1200+) from its weak DINrail and connected it via Lan to the GIGA client and - lo and behold - I can continue to use the adapter as a WlanPoint as before (the product does offer some advantages such as guest network and 2.4 / 5.0 supply), but now with a full data rate.
But people want more! So, after extensive consultation with the managing director of GIGA, Mr. Gipke, I connected the COAX cable from the GIGA Master to my EMP Centauri SAT Multiswitch ProfiLine 5/16 to a (freely selectable) OUTPUT and also connected my "replacement" ground COAX cable to a (freely selectable) OUTPUT of the MS. I now have a data rate of approx. 1500 / 1300 MHz at all F-terminal sockets of the star network incl. my "replacement" COAX cable in the adjacent building. The SAT TV reception / switch distribution is not affected in any way. Amazing! I am convinced that a solution via Tel cable would also succeed.
From my side -> clear purchase recommendation!

06.09.2021 Peter L. (Heraklion, Greece) Networking in the house via coax cable

Just coming back to inform you that everything is working flawlessly! Your device actually saved me a ton of cabling money! :D Previous PoE speed was 6mbps out of my max 50mbps! Once again, thank you very much!

05.09.2021 Jürgen Barth (Kraichtal, Germany): Distribution of 1Gbit Internet in the house via coaxial cable

I recently purchased and installed your equipment.
I was (and still am!) so excited that I posted a video on YouTube describing my journey from dlan to your products.

If you like the video, please feel free to share the link.
Many greetings from a happy customer.

20.08.2021 Darren T. (Zorneding, Germany): Home networking via coax cable

All setup, works perfectly. It's so fast it shows some issues in my network setup that I need to look into. Installing cat6/7 throughout the house would have been crazy (should have been installed when the house was built) but using the coax they put in for satellite instead is alot cheaper and arguably faster.
The full incoming internet provider bandwidth is available throughout the building now, my kids and wife are happy and we are setup for the on-demand streaming world expected by the kids.
You have a really nice product here!

01.08.2021 Felix Fechner (Tübingen, Germany): Connection of outbuildings via telephone cable (Google review )

I wanted to connect an outbuilding to the existing internet connection.
I failed with WiFi and Powerline because of the distance. It didn't even work to establish a connection. But: Both buildings have an old telephone system. I now use it to transmit the data via I simply feed the signal into the telephone system in the main building, connect both networks in the basement and I have Internet in the outbuilding. So it wasn't even necessary to lay any cable for this. At first I was quite sceptical because the telephone systems in both buildings are widely branched and certainly anything but interference-free. The distance itself is not without problems and the cables are not twisted (no twisted pair). But the system does not seem to have the slightest problem with this. I currently use only two cables (1 wire pair) and actually have the full bandwidth of 1.5 Gbit/s (sum of upload and download). You have to let that roll off your tongue! This is actually quite a bit of overkill for any normal application. I couldn't have wished for better support from GIGA Copper. Extremely friendly and just as fast and competent. I even got detailed answers to difficult technical background questions about encryption.
I have been using the system for almost three months now and can only warmly recommend it to anyone who wants to expand their home network over long distances.

Engelbert B. (Limburg, Germany): Networking between 2 buildings via telephone cable (simple "electrician" cable), 200m (Google review)

We have an old 2 or 4-wire telephone line connecting two infrastructures over a cable length of almost 200m. In the last few years, a master/slave modem from a well-known network supplier on a VDSL2 basis was used for this connection, but instead of 100Mbit/s it only delivered 15Mbit/s and this only with interruptions and small data throughputs.

It was only by chance that we became aware of the company from Düsseldorf. At first we were sceptical because of the above-mentioned points, but right away the company was there to help us in word and deed - for this, a big praise. With the two devices we purchased and the detailed explanations and ideas, we were able to eliminate faults and ultimately improve the line considerably. What can we say: A performance increase of 2800% (to approx. 435Mbit/s in both directions) and the whole thing without any disconnections.

If you have an old telephone line and want to use it as network infrastructure (colloquially network cable), stop searching and forget what you may have seen on the internet - you are more than right here! We can recommend the company Giga Cooper Networks from Düsseldorf without any reservations.

07.06.2021 Christian C. (Nürnberg, Germany): Networking via telephone cable between 2 flats (3rd and 4th floor) in an apartment building via the basement.

The package arrived today. Unpacked, plugged in and so far running like a charm. Great thing. Connection is up and running at 1855/1855 Mbps.

31.05.2021 Klaus W. (Elsdorf, Germany): Networking in the house via telephone cable

If everything were so simple: I discussed the task with Mr Goldberg on Thursday and was able to install the two devices without any problems on Saturday. Today's acid test in my home office confirms the efficiency with a 1a performance.
Thank you very much for the very good technical advice and your extremely fast and completely problem-free handling.
I will gladly recommend you to others.

20.05.2021 Jörg H. (Düsseldorf, Germany): Internet distribution in the house via telephone cable

Thank you very much for the great support. The modems were really the solution to our problem.
Using Powerline, the connection between the main house and the back house was a shaky 40 - 50 Mbps. Measured with iperf3. With the modems, the value is currently around 400 MBit.
The igmp EntertainTV stream runs stably without any further settings.

16.03.2021 Andreas C. (Salzgitter, Germany): Networking in the house via telephone cable

I would like to share positive results here once again.
I was sceptical all along, but the product works and I am thrilled.
House connection: Vodafone 200MBit DL / 25MBit UL Previously from the attic down to the basement via Zyxel Powerline Adapter, measured max. 66 Mbit DL.
With the installed GiGa Copper modem, measured 200Mbit DL. Top alternative if only one telephone cable is available. Many thanks

07.03.2021 Nico N.(Riederau, Germany): Networking between two buildings, 100m

I have just commissioned the line to my father's house. 1581/1470 on an estimated 100m line with two strands and 5 sleeves in between - adventurous:

I use a bell wire that was laid to our outdoor unit from the heat pump and had strands left over, go from there via an underground cable through a ditch, across the property, into my father's outdoor heat pump unit, from there into his heating system and from there to the network distributor.

Technology that inspires!

28.02.2021 Lars U. (Gößnitz, Germany): Distribution of fibre optics in a 3-party house from the basement to the 2nd floor

Yesterday I finally got around to trying it out and was very happy that everything worked without any problems during my short test. The maximum data rate of 1.5Gbit/s is achieved.

08.02.2012 Jürgen B. (Buchholz, Germany): Connection between residential house and horse stable via 60m underground cable, 2 access points and 3 IP cameras.

So I did find your advice "sketchy".

Otherwise you would have told me to bet in any case. Electrician with network knowledge and installer with electrical knowledge both swore that it wouldn't work with your boxes. Original comment: Why didn't you run a network cable up to the house (dig 60m!)?

And I didn't bet!!! In the first and second stall we have a download >600 Mbit/s! Just awesome!

Thanks a lot for the consultation!

01.02.2021 Tobias K. (Münsingen, Germany): Networking in the house via telephone cable

As already discussed with your colleague today, once again my very positive feedback - the devices helped me a lot and saved a lot of manual work!

14.01.2021 Jens Fischer (Glinde, Germany): Networking in the house via telephone cable, conversion from Powerline to (Google review) (Google Review)

I just wanted to give you the feedback that I am completely thrilled with the GigaCopper modems! The set-up was child's play (even though I couldn't restrain my curiosity and connected directly to the management interface of the devices ;-). After a few minutes of cabling, I literally got the green light on the line port. My bandwidth measurement was then also impeccable: I was able to achieve a whopping 780Mbps in both directions constantly over a 2 minute measurement period with iperf. This made my Powerline jealous, which had been dilly-dallying at around 35-50Mbps.

The first day of HomeOffice including HomeSchooling also produced a very good picture with several parallel video conferences, and I was also able to enjoy HD video streaming in the living room via yesterday as a test.

I am far from wanting to send the modems back. Rather, I am now squinting at the next two modems to bring my two ring wire lines into the next decade. However, that doesn't fit into the monthly budget anymore, so I'll have to let some suffering build up in the family for now. The new 4K UHD TV is coming next week, and if Disney+ only jerks or looks pixelated then I'll be forced to dig into my pocket again for the next two modems 😊

Top eBayer, happy to do it again! Oh no, it wasn't via eBay. I will definitely recommend GigaCopper and plan to publish a short blog post about my positive experience.

09.01.2021 Detlef Bühler (Frankfurt am Main): Networking in the home via telephone cables (Google review)

After struggling with other solutions for so long, I couldn't believe that the solution was so simple. I had the time and was able to install it as soon as it came (it wasn't difficult) and I now have a fantastically fast connection at my disposal when I would have been happy with a safe, simple speed. So of course I'm happy :-) I'm beginning to believe that my struggle for connection is over, because so far there have been no failures. In short, I'm very happy with the solution and I'm surprised that it doesn't seem to be very widespread, at least that's how it seemed to me. I have also rated it - positively, of course.

14.12.2020 Danny H. (Munich, Germany): Networking in the house via telephone cable

I am happy to report success.

For the first time in the years we've been living here, I'm watching TV upstairs. It's fantastic! Almost unbelievable! It's a dream come true. I can't tear myself away from the television. I'm now putting everything back together again so that I can set everything up neatly at the weekend.

Thank you very much for your help! It was and is sensational!

I am already looking forward to implementing more projects with you in the coming year.

Thank you from the bottom of my heart.
