There are a few things you can do to help reliability
You should first make sure that the modem and router are individually
set up correctly.
I do have a guide for that.
Once that is done you should consider giving out proper IP addresses
Big business does this for security and reliability and it is no different for home users except maybe easier
Read the guide for router and modem first and if any of it may apply to you then try and do it.
The second part deals with IP addresses and this may well help you
I have a selection of computers laptops servers at home on a small network
It is quite some time since I last had to do any sort of system wide shutdown
Try the following procedure and write down anything you change so that if you need to go back you know what was changed.
Connect ONLY the MODEM to a pc and nothing else
Go to the start menu and select RUN
In the box type "cmd"
Now in the black screen that has come up type "ipconfig /all"
Take note of the numbers that are in 4 groups e.g.
Also take note of the name in front of those numbers !
Take note of the DEFAULT GATEWAY
Now do the same thing with your ROUTER
If that too has the same IP as your modem in "default gateway" then you need to fix that issue as that is probably a part of your problems.
The fix for router modem conflict is to set the router to use a different IP range.
To do this only have the router connected (by wire) and open an internet explorer page (it will fail but that's ok)
In the address bar type the number you got for default gateway above for the router e.g. and press ENTER
When it asks for the user name, give it the one you gave it when you set the router up or the default one from your manual
Also give it the password you gave it when you set it up or once again the default one from the manual.
You now need to look for a box that has the number you just used to get into the router.
It may just say IP address or Starting IP or something similar
That is the number you should change. I usually change the third block e.g. as opposed to
You should also have some DNS numbers from the checks further up with the MODEM
You should find the DNS boxes and place those numbers in there. This will allow your computer quicker access to finding things on the internet
Now look for the save settings button and do so.
Reconnect the modem and router. The cable from the modem should go to the YELLOW socket on the router.
Power up the modem and WAIT until all the correct lights are on.
Then do the same with the router.
Now power up a pc and check that you can surf without problems
If not then the problem may lay elsewhere. Go back and re-check.
Now to issuing IP addresses and why.
The computer has to knock-on the routers door and ask for directions home as its address changes everytime it leaves home (switched off)
You are going to give it a permanent key to its own door. Write down all that you do once again.
The same applies to both wireless and wired connections.
You may get an occasional error regarding the IP address already being assigned tell it to ignore and go ahead.
Call up your control panel and select Network Connections
If you have more than one don’t worry
Right click the first one and select properties
Scroll down to Internet Protocol (TCP/IP) highlight it then click properties
There are boxes here where you are going to type numbers.
Click the "Use the following IP address"
If you changed your router to lets say Then I would use as the first number
The second box is
The third box would be (same as your router address)
The two DNS numbers at the bottom can be got from the numbers you wrote down early on when you just had the modem connected
Now click OK
If you have more than one connection available then go to the next one and do the same EXCEPT the first IP
I would use 192,168,2.11. The rest would be the same as before.
Now move on to the next computer and do the same again but this time in the first box I would jump by ten so the IP would be
Again if it has more than one connection then do the same as above and advance the number by one in the top box
Next machine same deal advance by ten. Once you have all your computers done then shut EVERYTHING down
Power up the modem and WAIT until all the correct lights are on.
Then do the same with the router.
Now power up a pc and check that you can surf without problems
If your problems are mainly wireless related the next part might be of use.
It is more than possible that the location of your router or co channel interference is causing disruption.
If its channel interference try setting your router to auto for channel selection.
If you are not getting any more than a 10mb connection to the router consider moving the router
It may be a problem with the windows wireless config
To turn of wireless zero config open control panel, click administrative tools, now services, then scroll down to wireless zero config.
Double click on it then click stop. Then set the service to manual. Make sure you click the APPLY button before hitting OK. You can now close the rest of the windows.
I would suggest at this point you also do a shut down and restart.
What you have just done is tell windows to stop messing about looking at other peoples wifi to see if it fancies something better (sound familiar ?)
You told it that it only has eyes for you ;-)
If you have any problems use the information you wrote down to back step to a working point and then double check from there
I know this looks like a lot to do but for most of us with more than a couple of computers at home it is usually worthwhile

    Then it has to be an issue with your itouch.

    A lot of portable/mobile devices may need specific funtions such as NAT or DHCP settings.

    These can usually be found on your router.

    Best bet is to find what it needs exactly and go from there.

Cable Network Routing with Zyxel 600

You have to set different ip address. To clear this up this how I got my setup. I have verizon internet. I use a westell 6100g modem, I have the local ip address set for and I got a linksys wireless router and the ip address set for Then I plug my modem into the wan port and it works. What am I doing is setting a static ip address from my modem to the router and using the router to distribute my address through the network. If you have any printers on the network you need to change that numter to 192.168.9.x number. If you don't have two different numbers set the router will take over.

Cannot connect wireless to internet

sounds like either you aren't really connected to your router, or there could be a software error. One other thing is wireless interfernce. Check the IP address of your laptop after you connect wirelessly. If it not somthing like 192.168.x.x or whatever your router assigns, if there is a differnt one from that, it is most likely interference wrong connection or bad router. Messege me on aim @ copter64.
