Hi!

Recently, my ISP has brought us 2 gbps home internet., and there is some thing to do. They said that, their provided ONT's ports can only produce 1 gigabit at one port, so if I want to use 2 gbit I have to plug 2 Cat 6a or higher cable to my computer. But my motherboard is an Asus Z270-F and it has one 1 gigabit port, so I have to buy a NIC. I asked them if will it be good if I buy a dual port 1 gigabit NIC, and they said yes, but card has to be capable of adding 2 speed at once. (1gbit+1gbit=2gbit)
Can someone recommend me a NIC that is affordable and can make this "adding"?

Port aggregation does not work all that well...at least the industry standard one. If they are using proprietary bonding then you would special software.

If you have the option it will work much better if you can use a 10gig add in card rather than trying to bond 2 ports.

802.3ad link aggregation can not actually increase the speed for a single file tranfer above the speed of one link. It does not load balance the traffic by packet which many times is called round robin. Unix has supported round robin forever but few network devices support it.

The best you can hope for is that it will run different sessions on different links. It is really stupid and uses math xor to pick the link with no consideration of utilization. It could put all your sessions on a single link and leave the other unused.

If it does not use 10g ports it may not be worth the effort. In real life usage most servers limit you to far under 1gbit. They don't want people with high speed connections to use up all their bandwidth blocking other customers. You could end up working hard to get this to work and then have no site available to really utilize it.

Do you need 1 or more devices with >1Gbs? fyi, none of the below will be easy to configure. Anything on wifi won't get >300Mbs. If you try and do bonded access points you will need a switch with bonding for sure. This isn't really needed if you don't have 20+ clients on one AP. The clients are usually the bottleneck, not the APs bandwidth.

#1 Many clients with 10Gbs NICs+10Gbs router load balancing+10Gbs switch. $2-3k+ investment

#2 1 or 2 clients with 10Gbs links, homebuilt router, 10Gbs NICs, 1Gbs switch $700-1k (purpose built switches latency are unmatched by any homebuilt router, it's not really a noticeable amount, homebuilt routers give you lots of options+ you can run other services from it)

#3 Clients with 1Gbs link on a switch with 2Gbs bonding to load balancing router $400-600 (can be added to above one for extra $500 to add shared 2Gbs to switch clients) each client would be limited to 1Gbs

#4 You can have different devices use different gateways so that a group of clients use 1 link and another with the other one. You would need a router with VLANs for this. This is the much less expensive option. $150-250 VLAN/load balancing router + 2 1Gbs switches. each switch would be limited to 1Gbs of internet.

1# and 2# will cost $100/yr in power or more.
spf+ is only viable in patch cables and they aren't long
cat6a 10Gbs needs to be installed by a professional to hit 10Gbs and you have to buy premade patch cables

What Failboat said. I have a client that gets 2gb+ from ISP and he spent 5k on his 10GB NIC for a vmbox.

Its not cheap to go over the 1gb range as it is not standard yet in the industry, so any solution to go above 1gb will start getting costly.

Unless you are running from enterprise situation or servers. I highly doubt you even need more then 1GB speeds to the NIC. I run 3 virtual servers from my house, one of which is a web server and another is a game server. On LAN I do not get close to using 1GB speeds...

Here is a how to on pfsense multiwan load balancing/failover using a gui to give you an idea of what you will have to do.
I'm not sure if load balancing adds to your latency or not.
Using two subnets with no load balancing will be the easiest to setup. This can be done with #4.

Thanks for the answers, but I dont want to make a whole network with 10 gbit. I contacted my ISP and they said that the Sagemcom ONT can not produce higher than 1 gbit on a single port so that's why I need to have that "2 cable" thing. I just want to go upper than 1 gbit on only one computer. I don't have to buy expensive switches because the other stuff (TVs, Other computers don't need that speed. They said that a nic with two 1gbit port will be good, but it has to made 2 gbit from that two ports.

That might make your desktop be able to accept a bond, but unless you plug both modems into the pc you still will need a business grade switch or router. You could try putting a cheap router on both modems and plugging them into your bond. This only gets 1 pc 2 connections.

Bonds are good for replacing a single link. the load balancing will do a better job of maintaining connections to various places.

This is the Optical Network Terminal that the Hungarian Telekom provides: Sagemcom F@st 5655v2 dtag
Also they can include a free gigabit switch if I don't have enough ports for the extra TVs and computers

And other than bragging rights, I can't see a consumer use for a single PC being able to utilize 2gbps. The servers you are connecting to almost certainly can't give you a feed at that level.
Now...if you were trying to spread that 2gbps over a dozen systems...then sure.

Yea... You are true but why they are providing "Home Internet 2000"?

Yes, but paying is not a problem the fee is only about $30/month

And what's the price for 1gbps? Less than that?

I'm just saying...going into a single PC, you will not see any difference between a 1gbps line and a 2gbps line.
Or even a 500mbps line.
5 years from now, maybe.

Like if they are selling 2 cars. The only difference is that one has a top speed of 200mph, and the other a top speed of 100mph. Everything else is identical.
Makes no difference if the road you drive on has a 75mph speed limit (all the servers you connect to).

I run multiple servers at once but not that company level where I need that ultra high speeds. They have a guaranteed speed, and luckily where I live not many users are using the "line" so I have nearly the fastest that is possible. Anyway the 1 gbps is $3 cheaper than the 2 gbps and all that fee comes with tv service.

Are they bonding it on their side? If so you don't need load balancing. You will need a router than can accept the bond and more ports available to bond anything you want to have 2Gbs. I don't see how their gigabit switch will do all this. You will still need a NAT somewhere. the isp could be running that for you.
