Disable ap/client isolation to allow chromecast to work

You need to login to the routers web interface and the settings will be in the advance WiFi section, probably a tick box. A typical web interface can be found at the following address in your browser Username usually admin and password could be password or blank or 1234 or admin. Check with manual.

NAT 3 in PS3 Router Zyxel P-660HW-T1 v2

Yeah I had this problem but she's fixed. No need to upgrade the firmware me thinks.

1) Type in "" into the address bar of your browser. The log in page for your browser appears.
2) Enter your password - by default this is "1234", but you might have changed it. If you have changed it before log in with that new one.

A page should load with a lots of boring information. On the left side there should be a panel of stuff, what you want is "advanced settings". If advanced settings IS there on the left go to step "a" below. If advanced settings (or in fact anything) IS NOT down the left proceed to step "b" below.

a) Happy days. All you have to do is click the "+" beside advanced settings to expand it, then select UPnP. Then just click ALL of the boxes (there's 3 of them I think). That's it.

b) You are logged into some sort of stupid mode where you can't change anything. All you can do is refresh the page or log out. This is probably because you entered "1234" as the password, but in fact this password has previously been changed by you or someone else. So go back to the log in screen ( in the address bar) and put in the one you changed it to, if you can remember it. If you do remember it and log in successfully (successfully being that you can see "advanced settings" on the left), go back to step "a" above. If you still can't get to that page it means you don't know your password. So you're going to have to reset your router. Go to step "c".

c) Resetting your router. Turn the router off. Then hold the reset button for 30 seconds and power on the router at the same time. Now I think you'll have to set up your router again like when you got if first, to connect to the internet, so do it. Then log in to again. This time the password "1234" should bring you to the proper screen with advanced settings. If it does go to step "a". If it doesn't go to step "d".

d) You'll have to default reset your router. Turn it off. Turn it on and hold reset for 15 seconds. Some light will flash. Release button and let it reboot. Now log in to again. If it works and you can select "advanced settings" go to step"a". If you STILL can't see advanced settings you're at the end of the line and I don't know what to do. Contact your provider or something.

If you haven't done this already...on your ps3:
Open up network >> internet connection. Choose wireless/wired - whichever you want. Choose "Address settings" - "custom", "IP address" - choose manual.Enter these:

IP address - ""
Subnet Mask - ""
Default Router - ""
Primary DNS and Secondary DNS same as default router.

Then enter than. Don't know what MTU is (it'll come up next). You're done.

My wireless zyxel router disconnects about every 30 minutes.

There are a few things thatcan cause you to lose wireless connection with your wireless router.1. Weak signal strength,check the signal strength on your wireless card. If it is weak move thewireless router away from brick or concrete walls and if possible locatethe wireless router higher up.2. Have you secured yourwireless router from people near your from unauthorized access? i.e. change thedefault password, setup encryption use WPA2 or WPA, change the default SSID,and turn off SSID broadcast, and for added protection, enable MAC addressfiltering which allows only the MAC address/es of your wireless card/s toconnect to your wireless router.3. You could be gettinginterference from electrical sources such as air conditioners, arc welders,washing machines etc. If so, the power supply to the wireless routers andcomputers etc should be connected to a surge protection power board, betterstill connect your computer equipment to an UPS (Uninterrupted PowerSupply). 4. Check the channels ofthe wireless routers and access points in your area and change the broadcastchannel on your wireless router to an unused channel or one that is currentlyused but has the weakest signal strength. This will minimize interferencewith your wireless router from other wireless routers and accesspoints in your area.

Advent 9315 wifi

How are you connecting to the internet? 1. Wireless 2. Wired This can have an effect on the speed. A wired connection is not subsceptable to any interference and wont slow down from it. A wireless connection can be slow because of the router, other things that broadcast radio signals, other things that broadcast non radio signals (like flourescent lights.) How are you testing the speed? Unless you go to a website that has a speed test program or you are running a speed test application, there is no way to know for certain that your speed is what you believe it is. Your speed can also change due to the amount of people on the internet and other things like equipment failure outside your house.
