Reset the printer back to factory defaults and try again. Power off printer and router. Power on router and wait 2 mins. Power on printer and try to connect now. If no joy, reset the router back to factory defaults and reconfigure it back to your settings. Try to connect now with your SSID and password.

Hp6700 Printer: can't connect to D-Link DI-514 Wireless Router when Broadcast SSID is set to NO.

HP6700 Printer: can't connect to D-Link DI-514 Wireless Router when Router Broadcast SSID is set to NO. My MAC LapTop and HP LapTop both work with the SSID set to NO. If I change the Wireless Router to Broadcast SSID is YES, then the HP6700 Printer can connect to the Wireless Router. I setup the Printer telling it what the SSID and Password were, the same as both of my LapTops, but it never connects, unless I change the Router to broadcast the SSID. Help!
This question was solved.

Did you try updating the firmware on the DI-514?
You can also try setting a static IP on the printer, then assign the printer to the static DHCP list in the router interface.
To give your printer a static IP address:
- Print a Network Config Page from the front of the printer. Note the printer's IP address.
- Type that IP address into a browser to reveal the printer's internal settings.
- Choose the Networking tab, then Wireless along the left side, then the IPv4 tab.
- On this screen you want to set a Manual IP. You need to set an IP address outside the range that the router automatically sets (called the DHCP range). If you do not know the range, change the last set of numbers (those after the last '.') to 250
- Use 255.255.255.0 for the subnet (unless you know it is different, if so, use that)
- Enter your router's IP (on the Network Config Page) for the gateway.
- Enter 8.8.8.8 for the first DNS and 8.8.4.4 for the second DNS. This is Google DNS. You can choose another external DNS if you wish.
- Click 'Apply'.
Now, shut down the router and printer, start the router, wait, then start the printer.
After this you will have delete and re-add the printer on your Mac.

I can sometimes connect to my Wi-Fi network, but sometimes the name of the network doesn't even appear when i try to find available networks. Is it possible that my software is too new for the network?

Some users with various Wi-Fi connection problems have reported that they were given the following instructions by Apple Support, sometimes with success. I can't vouch for this procedure myself. After completing the procedure, you'll have to recreate all your settings in the Network preference pane. Make sure you know how to do that before you begin. Taking screenshots of the preference pane may be helpful.
Step 1
Back up all data.
Triple-click the line below on this page to select it:
/Library/Preferences/SystemConfiguration
Right-click or control-click the highlighted line and select
Services ▹ Reveal
from the contextual menu.* A folder should open with an item named "SystemConfiguration" selected. Move the selected item to the Trash. You may be prompted for your administrator password.
*If you don't see the contextual menu item, copy the selected text to the Clipboard (command-C). In the Finder, select
Go ▹ Go to Folder...
from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
Step 2
Reset the System Management Controller

I CANNOT PRINT FROM MY IPHONE 4 TO MY BROTHER 8890DW PRINTER WHICH IS CONNECTED TO MY TIME CAPSULE/NETWORK VIA ETHERNET CABLE???

Why can’t I print from my iPhone 4 to my brother 8890dw printer which is connected to my time capsule/network via ethernet cable??? My iPhone does not even locate my printer,even though I have no problem printing from my Mac to the same printer.

Typing in all caps indicates shouting, is considered rude and is difficult to read. Many simply do not read such posts.
You would need an airprint enabled printer or an app that proides printing function.

Can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously

I can't connect Airport Express wirelessly to network so that AirTunes and internet are available simultaneously. My old AE allowed this but can't make the new one work that way.

In your instructions, you say to use the same encryption type as the router has set up. well, I am using the WEP 64 bit encryption and the Airport Utility does not have this...it has 40 bit. Is this a problem, or do I have to be using a the same type of encrytion ?
WEP is available in either 40 or 104-bit, but is usually "advertised" as either 64- or 128-bit respectively. For example, 64-bit WEP uses a 40 bit key (also known as WEP-40), which is concatenated with a 24-bit initialization vector (IV) to form the 64-bit RC4 traffic key. So, WEP 64 on the Linksys & 40-bit is equivalent.
What concerns me more is the loss of bandwidth performance you are experiencing when connecting the AX. When the AX is configured as a wireless client it is acting just like any other wireless devices (computer, laptop, printer, etc.) and not like another router. This should cause little or no bandwidth loss. True the more secure the wireless encryption used WPA2 vs. WEP, the more overhead is required for security, but the differences you are seeing seem excessive.
It is very possible that you may have some form of Wi-Fi interference in the immediate area that is preventing your Linksys from providing a good clean signal.
I suggest you perform a simple site survey, using utilities like the following to determine potential areas of interference, and then, try to either eliminate or significantly reduce them where possible:
For Macs:
o MacStumbler
o iStumbler, or
For PCs:
o NetStumbler

Can't connect to my home WiFi network

I'm using a linksys router and using WEP security. The iphone can see my network, but when I enter the password it tells me I can't connect. I can't seem to make the phone forget the network so that I can start over.
Any help would be appreciated

I have the same problem. I can't connect to any password protected networks. I type in the correct password, but I'm unable to login. I don't have the option for the iphone to forget the network, because I've never been able to log in and therefore there is nothing to forget. The option doesn't even come up. Is anyone else having this problem? It is this way for 2 different networks.

Can't connect to any secure WiFi network. Help...!

Hello,
I am unable to connect to any secure wifi network. Using iPhone 5, Model : MD300B/A, Software : 6.1.4 (10B350). Whenever I try to connect to any secure wifi network, it says password incorrect. But it connects fine with unsecured networks. Double checked the same secure networks with my iPad and it works fine. Tried reseting the network settings and all settings. Updated to latest firmware (6.1.4). Still not working.
Please help.
Regards,
Madhavan

Samsung WiFi printer can't connect to new Quantum Gateway router?!

We recently replaced our 3-year-old router with the latest Quantum Gateway router and upgraded fios speed from 25/25 to 50/50.
Every device (PC, phones, tablets, and TV) was able to connect to the new network. BUT, our Samsung Wifi printer (M283x seriers) cannot connect at all. With the older router, we were able to access the printer thru Wifi network from two different PCs..
We did not relocate the router and we did not move the printer, so singal strength was not the issue. We even uninstalled and then re-install printer driver to PC to set up the network again. Tried every connecting option that Samsung had suggested, but everything failed.
We also tried to log in to Router Admin site to add this printer, didn't work. WPS was turned on and we couldn't figure out why this new network doesn't add the printer. This router did not like our printer.
One funny thing was that if we turned OFF all the security settings, the router allowed this device to connect to WiFi.
Can anyone help? Thanks a lot!
Solved!

I have a solution for you. After upgrading to the Quantum Gateway last week, My Samsung 2835 printer had the same problem. It turns out that the printer doesn't play well with the Quantum Gateway when the Samsung "Wi-Fi Direct" function is enabled. All you have to do is log in to the printer web page. Then, under Settings--> Network Settings--> Wi-Fi Direct... Turn Wi-Fi Direct off using the drop down menu. Hit "Apply", then power cycle the printer. After this you can use WPS or manually configure the printer and it will connect right away. Thank the Verizon technical guy J.W. for figuring this one out by capturing the Wi-Fi traffic between the Gateway and printer.

SOAP / WSDL LabView 2010 can't connect to local webservice of network printer

Hi,
we are using a Labelprinter from cab (www.cab.de) that supports a webservice.
IP: http://192.168.1.66/services.wsdl
When i use this link in FireFox i will get a XML file (see attachment). The company "cab"
has an example using NetBeans to write a deskop application using Java. I tried that and
i was able to connect to the webservice.
When i do that with LabView 2009 or 2010 i get an error message:
1. URL doesn't exist or WSDL is wrong
2. authentification failed
3. proxy settings wrong
to 1)
i'm shure the link is ok, i can't connect to it with Netbeans (i used copy & paste to be sure)
to 2)
In Netbeans it is not possible to enter a user and PW. But anyway i have use the standard
soap user the was given by the company.
to 3)
don't use it
The last point is, that there is an error in LabView 2009 and 2010, e.g. error parsing the XML file?
Can someone help me?

My printer can not connect to WiFi if there are two or more APs with same SSID

I tried to connect my printer to WiFi but failed.
My network has more than 2 WiFi APs and all the APs have the same SSID and security settings.
I found that the printer can connect to WiFi only if I left one AP on and turn all other APs off.
Other devices like notebooks, smartphones all works fine with these APs.
Any solution to solve this problem?

No, I gave you a solution to try, you rejected it. BTW using channel 3, it is getting clobbered by all APs on channel 1 and channel 6. If you use channel 1, you only have other APs on channel 1 to contend with. That's why you should only use channels 1, 6 or 11 on the 2.4GHz band.

Can't connect AE to existing wireless network

I can't get my AE to connect to my existing wireless network. I saw the other thread on this and followed those steps, but it didn't work. Here's what I did:
1. Connected the AE to my D-Link DIR-655 wireless router via ethernet cable.
2. Opened Airport Utility and established a connection to the AE.
3. Renamed the AE and entered a password.
4. In the "wireless" tab, I selected "join existing network", chose my wireless network, selected the security type (WPA Personal) and entered the password.
5. In the "music" tab, I named the speakers and entered a password.
So far so good. I clicked "update" and the AE restarted. After a while I received an error message informing me that the base station could no longer be detected. According to the directions posted in the other thread, this is actually supposed to be a sign that the AE is now in client mode and all is well.
I unplugged the ethernet cable from the AE and router and then went to the other room. I plugged the AE into the speakers and then plugged the AE into the wall.
However, instead of a green light all I have is a flashing amber light, even after several minutes. No connection.
I reset the AE and repeated the steps above, to no avail. Still a flashing amber light.
Any ideas?

I'm having a similar issue. My AE is connected directly to a Netgear WGR614v4 router, and I run through all the steps you mentioned. When I choose to update the settings to the AE, I get the same "error" you mentioned about the AE not being found, and I also took that as a sign that I'm in client mode. I moved the AE to the other room, connected my mini cable to the stereo, then plugged the AE back into the wall. The AE runs through its setup and eventually gets a solid green light, so I'm thinking all is well.
The problem is that I then log back into the AirPort Utility on my laptop and the AE is not shown in the top left like it should be. After doing a bit of reading, I've figured out that I can manually find it by going to File>Configure Other and entering the AE's IP address and password. Then I get a window showing the details of the AE, its name, network, encryption, etc. However, if I close this window, it still doesn't show up in the main AirPort Utility screen and I'm not sure how to configure it for AirTunes.
Hoping that's just a bug with the AirPort Utility software, I open up iTunes to see if I can locate it there. I know I should see a pulldown menu at the bottom of iTunes that gives me an option for AE as my audio output method, but the menu is not there. Now I'm completely stuck.
At this point I decide to start from scratch, so I do a Factory Default reset by pressing down the reset button on the AE as I plug it into the wall. Now it is supposedly reset, so I plug it back into my router, then it runs through a setup sequence and lights up solid green before I've even done anything. It shows up in AirPort Utility with a default base station ID, but my computer won't connect to it at all. I'm hoping I can try to reset it again this evening and at least get back to the normal setup screen, but I'm really not sure what I could do differently at this point.
This is frustrating and I'm on the verge of giving up, but I REALLY want this to work out.

Can't connect to MacBook via shared Network

Hi there! I was wondering if someone could help me with this. I just recently installed Tiger OS X 10.4 on my old iMac G4 Flat Panel, and would like to move some files over. I know I can do it with Target Disc Mode using the firewire, but it takes too long, and I would rather do it with the Network.
However, my iMac will not connect to my MacBook (MacBook has Leopard 10.5.8), either with the IP address or with Go-->Network. Whenever I try I get an error message that says "Connection failed. The server may not exist or it is not operational at this time. Check the server name or IP address and try again."
Now, what get's me, is the MacBook will connect to the iMac, but not vice versa.

Oh, I thought you had to have the computer you're transferring files from in target mode. Oh well. If this doesn't work, then I'll try that, I guess.
Yes, I have File Sharing enabled on both computers. When I try it using AFP, it doesn't ask for a password, just says it can't connect. (AFP is what I used when the MB connected to the iMac, but the iMac won't connect to the MB through AFP).
Just now I chose SMB sharing on the MB and used my MB password and it accepted it. BUT, when I went to the iMac and tried to connect via SMB, first it said that this computer's (meaning the iMac) Internet connection is offline. Of course it is - I don't have an airport card yet for the iMac and there's only one Ethernet port, which I'm using to connect the two computers. I tried it again, and this time it said "The Finder cannot complete the operation because some data in "smb://[ip address]" could not be read or written. (Error code -36)." I tried one more time and got the same message.

Can't connect to my wi-fi network

I cannot connect to my wi-fi network. The phone finds it but when I choose it, it simply tells me that it is unable to join the network. I am thinking it is a password issue but the phone never asks me for my password. The wi-fi is locked so it needs a password. I do not have this problem with my laptop or my Ipad so I know the wi-fi network is working correctly. I just can't figure out how to get the phone to ask me for my password. It should do it without any prompting, but for whatever reason it does not. Any suggestions?

I figured it out! I had to go to Settings>General>Reset> and there select Reset Network Settings. Once I did that, the problem resolved itself.
