WPA2 is an option under the WPA Personal or Enterprise Wireless Security Mode section.
You should select WPA Personal then can you try the following?
Set the WiFi mode on the 657 from Mixed all mode to Single mode G, 20Mhz Only, WPA and TPIK only.
You'll need to reconnect the printers WiFi and the iphone to the routers WiFi SSID again.

Then test with Mixed G and N only, 20Mhz, WPA2 and AES Only.

Any other WiFi routers in the area? Link> Use InSSIDer to find out. How many?

Keep channel 1 for now.

Keep us posted.

There are about 12 other routers in the area and 3 of them are also on channel 1. But they are the same 12 that are there when I use the Linksys router so I can't see that being an issue. I honestly don't think this is a router "setting" that I can change. I have also been on Apple forums trying to see if the problem lies there and found this thread to be very interesting: https://discussions.apple.com/thread/4936567?start=15&tstart=0

Since I don't have an issue using a different router, I'd say the problem is with the D-Link router blocking port 5353. What do you think?

[FurryNutz]

So this was working before updating iOS as you stated in that Apple thread?

If you have several other WiFi routers near by, this can be an issue. Especially with newer generation routers that have the "Good Neighbor Policy" thats in all newer Mfr WiFi as a standard:
http://www.wi-fi.org/knowledge-center/faq/i-heard-wi-fi-certified-n-products-can-cause-interference-problems-other-wi-fi

Older generation routers did not have this and thus are brutes on the block an can be a cause of interferences or if your Linksys is an older generation router, you might just not see this. It seems that your iphone is making the connection via the router to the printer, however after a while, it fails. It tells me that the router maybe having problems with some interferences in your area.

Try setting Medium or Low power output settings and test again Under Advanced/Advanced Wireless.

I thought it was the iOS update at first, but I wasn't certain since I don't print from my phone all the time. It was also about the same time that I got this router.

Setting the power to low or medium had no effect. Well, that's not entirely true. When I set it to low and then rebooted, I was able to find the printer for the standard 2 minutes that it will connect when I make certain changes in the router, meaning that I am not able to find the printer for 2 minutes every time I make a change and then reboot the router.

I understand that other routers and Wi-Fi devices in the area may cause interference, but why would it only affect my iPhone's ability to see the printer? I have no other issues at all. Never a problem with dropped connections even with all my devices on the network connected at the same time.

I have also downloaded and installed Bonjour Printer Wizard here: http://support.apple.com/kb/DL999

I can not find the printer using that tool either which is leading me back to port 5353 being blocked by the router.

Any chance you have a different DIR series router around? Could you by chance go to a local computer store like best buy or fry's, they have refund policies. I would give a different DIR series router a try and see if the problem still appears.

I don't have a wireless native printer, however I do have a wireless print server that I connected yesterday. I might give this set up a try and see if I can at least print from my iPhone to my LaserJet connected to this wireless print server. Are there any apps or configurations needed to print on the iPhone. I've never printed in this fashion before so just need to know the setup process.

I've sent a email to D-Link asking for review of this and see if I can get some information on this.

[pnl321]

I really don't want to buy another router right now since money's a little tight.

There are no apps and configuration should be automatic. Just pick a picture or note that you want to print, click the "action" button in the bottom left corner, select print and it will automatically attempt to find an AirPrint enabled printer. Once it does, you should be able to click the print button to start printing.

[FurryNutz]

Understand man...

Let me try this after work today and see if I can reproduce it with what I have and connected to the 657.

[FurryNutz]

Well I fiddled with my Wireless Print Server connected to the 657 and my LaserJet. I wasn't able to see any AirPrint available printers on my 4S. I presume that this is probably due to the fact that I don't actually have any AirPrint printers that support this Apple feature. Just putting a wired USB printer on a Wireless print server doesn't seem to work for me and I don't have access to a printer that does.

My Mac book was able to connect to the Wireless print server and print to it. I presume this was via IP or maybe Bonjour protocol however my print server is several years old and may not support AirPrint either or Bonjour.

Only thing I can think of is that something is interfering with the connections for Airprint since you can get a connection for a short duration then it stops. Or something in FW is possibly not working right with Airprint.

Not sure about port 5353 even thats mDNS thus Bonjour protocols.
It's worth a try maybe if you use Application Rule and set up a rule for your iPhone using it's IP address, reserved, and input the 5353 port number for both Trigger and Firewall, UDP for both Traffic Type and see if this does anything. since you are on a LAN to LAN side connection with the iPhone and the printer, not sure if doing this will help since using Application rules is for WAN to LAN connections.

Tried and failed. Good suggestion, though and I do appreciate your help. D-Link's "customer service" is useless via e-mail and I was on hold for 42 minutes Monday before I hung up and got on with my life.

[FurryNutz]

If you got time, try doing the same thing under QoS. Remove the Applications rules and set up the similar rules in QoS. Not sure if this will help either.

Email support can't handle this level of support, so phone and level 2 or higher is needed here.

I'll forward this on to D-Link and see if I can get any help on this. Can't guarantee anything. Please be patient.

[FurryNutz]

Also had another idea for you as a suggestion and it could work, and should. Connect your Linksys router wired up to the 657 in AP mode. SSID and PW can be the same however make sure the channels are different. You could possibly use different SSIDs or make sure the Linksys router is closest to the wireless printer and make sure it connects to the Linksys router running in AP mode. I'm curious if your iPhone connected to the wireless on the 657, will it print thru the 657, via the Linksys in AP mode to the printer then?

I presume if you connected the iPhone to the Linksys in AP mode it should print there too.

[FurryNutz]

Also, on your 657 under Advanced/Firewall do you have optional NAT settings for UDP and TCP by chance?

Can you review this and give feed back?
http://forums.dlink.com/index.php?topic=45869.0

I'm curious if changing the NAT settings and disabling Multi-cast could help here.

Let us know...

[pnl321]

The one time I was able to talk to someone at D-Link, they also asked about NAT settings. Maybe that's the problem, but there is no way to change those with the DIR-657. Also, I have tried enabling and disabling multicasting and it doesn't matter.

It also bothers me that they want to charge me to get a higher level of support than just the basic customer service person you get when you call. The router is only 4 months old now and I will not pay to fix a problem that shouldn't be there in the first place.

[FurryNutz]

I have passed this along to D-Link for review. There could be a protocol thats not being passes or being properly used on the 657.

Please let us know if you can try out suggestions in post #25 and see if this helps any.

I am very reluctant to try that suggestion for 3 reasons.
 
#1) I will have to reconfigure my network and reset the Linksys to factory settings due to the current configuration and security settings. I have MAC address filtering enabled on that one and I had problems with connecting to the router the last time I disabled that.

#2) I don't plan to use that setup ever so it is a moot point whether it works or not.

#3) Communicating to my wireless printer that is on the current network should not be this difficult. If I can establish a connection after changing settings in the DIR-657, but then lose it a couple of minutes later, there is a problem with the router or the firmware and nothing else.

I do appreciate your help, but I am not going to jury rig my network to enable a function that should work under normal circumstances. This is a D-Link problem that needs to be fixed by them. Unfortunately, I also don't have all day to wait on hold hoping someone picks up the phone when I try to call for in warranty support.
