iphone cannot access my wifi at home

Sounds like you do have a password on your router and you at one time told the laptop and forgot that you did.

Go access your router and check the settings.

If you have a friend with a laptop, have him come over and see if he can access your network. That should tell you definitely if there is a password access. I assume we're talking about either WEP or WPA. On your IP, if you go into WIFi setup, you will see your home network. If it has a paddle lock symbol, you have a password.

Who set up your router?

When it was done, did who ever do it write the password down in the manual for the router as recommended?

Find the manual. It will either have the password, or you can use it to reset the router correctly and write down the password in the manual.

If its asking for a password, you can rest assured it has one.

If you don't have your wifi protected with a password then you should set up some security right now!

No password means next door neighbours, passers-by can log into your router, change settings, access the internet via your ISP account. At best, "outsiders" eat up your download ISP allocation. There is a worst!

You only need to enter your password once - your phone will remember it for next time.

You might have 2 things going here. The first is the router which may have a restriction that only allows WiFi devices that have registered MAC number access. The second possibility is either WEP or WPA protection. With either of these, all you have to do is enter the "string" once and you IP will remember it.

Either way (unless you find the "string") you're going to have to go into your router software. Of course, to do that, you're going to have to have a "string". The default router User name is usually "admin" and the Password is "password" (I think). If neither of these work, you're out of business unless you can reset the router password. If you get the name and model number of the router, you can probably access the manual online for information about reseting the router back to factory defaults.

Or you can just buy another router and start all over. I've seen them for around $50 and probably less than that on eBay.

I'm confused now! lol.

Why are you replying to my comment? I wasn't asking anything - just trying to help the OP.

WEP
WPA
"string"???
Fancy stuff for the OP, considering their self-confessed lack of IT jargon/knowledge.

... it took me quite a while to work out your "IP" means iPhone!! I was trying to work out how "Internet Protocol" worked in that sentence. Considering the subject here, perhaps its best to use "iPhone"! lol

It seems a bit drastic to buy a new router "to start all over". Thats what the router's reset button is for isn't it?!

and "string"??
sheesh

Excuse me Tom.

I was doing a quick reply and didn't mean to be replying to your comment at all. As to whether the originator of this thread could understand my reply or not, I'm not sure.

As to your quote appearing, I didn't mean for that to happen. You raised some great points and I was using them as a guide in my post. I must have had a brain fart because I didn't go back and "clear the slate" for my "crutch" use of your post.

As to buying a new router, that was a throw away line in case the whole procedure was too much for the original poster to follow. And of course, I'm no expert are "zeroing" out routers. I think my present one has a reset feature, but I have to hold the button in for "so many seconds" for it to work. Also, for someone not familiar with setting up a router AND they don't have the setup disk or the manual, it might be easier just buying a new one.

Before going to that method, I would certainly recommend once again getting on the internet and seeing if there is any help on the manufacturers website.

Once again. sorry for replying to your post (especially the quote). However, I see people replying here to the next post above while they're really replying to the originator of the post.

Ok, now I have a different question: My IP would not connect to any WiFi router that has an encryption WPA2 or higher.
Also, if the said encryption is WEP - it would not stay on the WiFi mode, it would immediately jump on the 3G network.
I looked around and I couldn't find any restrictions as far as the encryption algorithms IP accepts, and at this time, although I turned off the SSID and the I put the MAC filter on, I would feel much better if I knew the limitations.

So, any suggestions?

Thank you, and I hope I didn't thread jack here...

I'm using WPA without any problems. FWIW, I read somewhere that MAC filters can cause problems with reliable connections. Also, I think the recommendation is to turn SSID on. I think these suggestions assume you either use WEP or WPA.

For what it is worth I would suggest that you make sure that the router is running the latest version of the firmware for that model. At first my 802.11/n router would only allow iPhone connectivity when it was running WPA security until I upgraded the router software now it will run WPA-2 without any problems.
