Wifi Antenna Question

I have purchased a new ac router and a new ac pci-e network card (Asus).

My setup before this purchase was this, pci-e 802.11n with two antenna connectors. Each connector has a 30 ft Wifi extension cable leading to two simple yagi antennas mounted outside. This has been working just fine for several years.

My new ac network card has 3 connectors.

Do you think that I could just buy another 30 ft extension cable and another antenna like the ones I already have. Should it work?

The reason I am inquiring is the antennas are advertised as 2.4 ghz. AC standard will be in the 5 ghz band.

Shouldn't the cable and antennas use whatever ghz I am working with?

Thanks

Hi there

IMO the best way would be to either reflash an old router with DD-WRT or or use a second router as a WIFI - Ethernet bridge. Saves loads of cables and if you just want wifi you don't need the Ethernet bit.

The advantage of using a second router is that you can use the 5GHZ wide broadband bit on your INTERNAL network even if your main Router is fixed by the ISP / Cable company so you can't tinker around with some of those settings. You set the second router up to where you need it and plug in Ethernet cables between computer / device to the Ethernet ports. Otherwise simply use the second router as a Wireless repeater -- more flexible and better quality than the cheap standard Wifi extenders often seen in the stores.

Decent Router / Wifi bridge should give you up to 433Mb/s on Wifi these days --plenty fast enough for your Ethernet (or even wifi) connections. You won't yet get theoretical maximum of > 800 Mb/s yet with this system but at current speeds I wouldn't complain.

Ensure second router's wifi is set to use a channel well away from your primary router's wifi.

BTW when setting up / taking out ISP / Broadband contracts there's an increasing trend for the cable/box / modem to be so "dumbed down" that it's almost impossible to make any changes like switching channels. Check that there's some user adjustment allowed on any router you get from ISP when signing up for the deal.

Even in my SHED a long way from the main house and using "G" I'm still getting decent throughput using Ethernet / Wifi bridge (the router I hobbled was an old one and can only do B/G but it's good enough for "The Shed"). Flashed with DD-WRT for Ethernet Bridge.
