Question about Zyxel Prestige 660R Router (91004397002)

1 Answer

EMbarq/Zyxel 660R/eHarmony/Windows Don't Play together well

I run a home network with a Zyxel 660R to a NetGear 8-port Gigabit Switch to 2 wired Macs, a wireless access point and 1 wired PC running Windows XP. Embarq is my DSL provider.
My renter runs the PC and is unable to connect to the eHarmony web site. It does not load.  I can access eHarmony from all of the Macs on the Apple software, but they will not connect using Windows XP in Parallels on the Macs.
Further more, the PC has been removed to a different cable modem network and it accesses fine - so we know it is not the PC.
Embarq support acknowledges the problem, but states they have no solution at this time. 
Any solutions or suggestions?  This is the only website we have ever run into this problem.  I suggested my renter just stay single.

    I have the same problem, eharmony will not load, it is the only website that will not load.

    I have the same issue. It's obviously a promblem generated by Embarq. Why doesn't Embarq fix this?

    Same problem with eharmony and embarq. is there a fix yet? why would this be the only web site I have had a problem with? Everything is good with the Time Warner cable modem when I connected back to it. I thought it was the web site or my PC. But not so! It must be Embarq DSL. Needs a fix from some side.

    I have the same problem, my mac was fine until I upgraded to Leopard and now my eharmony will not load properly and eharmony will not help me fix it.

    does anyone have a fix for this yet? this is ridiculous...

  • Anonymous Apr 03, 2009

    I have the same problem. I was able to access eharmony up until last October. Embarq tech support acknowledges this problem but has no solution.

  • pamcd Apr 04, 2009

    I can't access eharmony, I called Embarq and they had me disconnect their firewall. Then I was able to access eHarmony..............HOWEVER........within a week I picked up a virus that blew my computer away, and I have Norton Antivirus firewall and windows firewall. whatever!! So I reinstalled Embarq firewall, no viruses, no eHarmony.

Upgrade to the latest firmware on the modem, disable the modem firewall, or bridging the modem will resolve this

Can i connect swc-5100wn to zyxel p-660r to make a wifi network

Yes unplug power from both devices then connect the yellow ethernet port on the Zyxel modem to the input on the router, there should be 5 ports on the back 4 together and 1 separated slightly from the other 4, plug into the separated port.
The 4 ports toegther are the output of the switch and go to your hardwired computers if any.
Plug in your modem to power, when it has synced back up then plug in power to the router.
Now all you have to do is hard wire 1 computer to the router while doing the router setup and follow the instructions with the router.

Hi I would like o hook up a netgear prosafe 8port gigabit switch to my pc and run an ethernet cable which is allready hardwired to my sony bluray player so I can enjoy netflix

It would be much easier to use a simpler device, namely any Netgear 10/100 wireless router.

Cable-modem (or DSL-modem) --> Router's WAN port

Router's LAN port #1 --> your desktop computer
Router's LAN port #2 --> your Sony player
Router's wireless adapter --> your iPod Touch's WiFi adapter

Since the cable-modem (or DSL-modem) is only delivering 5 to 25 Mbits/second to your router,
unless you are paying a _lot_ of money per month to your ISP,
there's no need to buy/use expensive "gigabit" equipment.
