I am trying to set up my new iPad. it asks for a WiFi connection.. I have one..then the next page asks for these things:DHCP,BootP,Ststic then IP address, Subnet Mask, Router, DNS, Search Domain, Client ID then HTTP Proxy I have no idea what any of this means...can someone please help me???
Thank you sooo much. I was so disappointed...I couldn't wait to get started with the new iPad..then ran into the problem. So simple. You made my day. Thank you for your expertise!!

My network has not been working today. When I click on it it says "unable to access nhe network". My guest network will work. When I hit the blue arrow on the right hand side of my network there is no information in the IP address, subnet mask, router, etc. There is information in my guest section when I checked. I have unplugged and replugged my router and turned my Wifi button of and off, started and restarted my Ipod as per internet suggestions. Would anyone know how to get my network reactivated. I am nervous to hit reset network settings in case I lose all my music and icons, etc. added since I got my Ipod. Thank you for any assistance
Do other devices now connect?
Did the iPod connect before?
What encryption/security is the router using?
Try:
- Reset the iOS device. Nothing will be lost
Reset iOS device: Hold down the On/Off button and the Home button at the same time for at
least ten seconds, until the Apple logo appears.
- Power off and then back on the router

Assigning non-standard subnet mask to local IP address on WRT54GX
I need to configure my WRT54GX V1 as an access point. I know how to accomplish this, but our corporate network uses a subnet mask of 255.255.252.0 How can I assign this net mask? The only options are contained in a drop-down menu and what I need is not there. Is there a different way to assign the subnet mask rather than using the menues?
It is a known limitation of Linksys wireless routers that they only support LAN subnets up to 255.255.255.0. I guess the assumption was that the router only runs LANs for up to 253 LAN devices. The plain access point setup (i.e. uplink through LAN-LAN connection) was never properly considered an option although it is documented in the Linksys easy answers.
Anyway, to set up the WRT as access point the LAN IP address of the WRT and the subnet mask is not important for the wireless connectivity into the LAN. The LAN IP address and subnet mask is only relevant to access the web interface of the WRT to make configuration changes. You have to make sure that the DHCP server on the WRT is turned off and that a LAN port of the WRT is wired to your existing LAN.
For the LAN IP address setup you have three options:
1. Use an available IP address inside your LAN and use subnet mask 255.255.255.0, e.g. if your LAN uses 10.0.0.0/255.255.252.0, assign the WRT an IP address of 10.0.3.200 with subnet mask 255.255.255.0. Of course, in that case you are only able to access the web interface of the WRT http://10.0.3.200/ from a computer in 10.0.3.* because that's the IP subnet which the WRT thinks is connected to its LAN ports. You cannot use a computer with IP address 10.0.{0,1,2}.* because the WRT does not know how to route these IP addresses. If your computer has an IP address outside the configured WRT LAN subnet you must temporarily change the IP address of the computer.
2. If you assign a LAN IP address and subnet mask to your WRT which includes a network router you may be able to get full connectivity by setting up static routes in the WRT. For instance, if you assign 10.0.3.200/255.255.255.0 to your WRT and your main LAN router sits at 10.0.3.254/255.255.252.0 you may be able to set up static routes for destinations 10.0.0.0/255.255.254.0 and 10.0.2.0/255.255.255.0 (or if it works even simply destination 10.0.0.0/255.255.252.0) to gateway IP address 10.0.3.254 on the LAN interface. Traffic from the computer to the router should go directly while the responses from the router to the computer go through the main router. I think this should work although I am not 100% sure.
3. Use any IP address outside your LAN, e.g. the default 192.168.1.1/255.255.255.0. Again, you must temporarily set up a static IP address on your computer to gain access to the web interface. But even with a LAN IP address outside your LAN the WRT will still bridge wireless clients into the LAN as it is supposed to do. -
I have recently encountered a problem with my system and the assigned IP Address and was not sure why. I have a wireless connection on the iMac with it setup to get the IP address automatically but the system gets the wrong subnet mask every time. It gets (255.255.0.0) the correct subnext mask in the other mac's is (255.255.255.0). Where is it getting the inappropriate address and why does it didn't assign the correct one!!
Are you sure that both these macs are getting IP addresses from the same place? (1 wired, 1 wireless...might mean that mac2 is getting neighbor's wifi)
Are you certain that this trouble mac is configured to be fully Automatic in the NetworkSystemPreferences?
"Conigure IPv4...Using DHCP" ( not manually, not dhcp with manual address, not bootP...)
Have you done a cold start to all your network devices (macs, router, modem, network printers?)
Power-cycle them off. Count 2 minutes. Start up modem, pause. Start up router/BaseStation, pause. Start up mac(s).
You haven't said what kind of router/baseStation you've got. 'Twould help, maybe.
added: Do you have a wireless modem/router AND a wireless airportBS/router/something)?

"IP and router address not consistent with subnet mask"
Hi all,
i have one of the old Powermac G5's running os x 10.3.5 "Panther" with a dual 2.5ghz processor, 512mb or ram, 160 gig hd, and no wireless card. I've been trying to hook the computer up to my network via an Ethernet cable (I have a Linksys WRT54G series router).
the problem is this: When I go through the Network utilities using the "assist me" option, select the LAN option, put in the necessary information (IP address, subnet mask, router address, and the dns host), and select continue, this message pops up:"IP and router address not consistent with subnet mask".
What I've found is that no matter if the computer is plugged in with a cable to the Ethernet port the message comes up which is very unusual.
Thanks in advance.Have you verified that you indeed have the proper subnet entered?
Why don't you just let the Mac obtain its ip address from the router via DHCP? -
Manipulating ip address and subnet mask with plsql
Hi,
I'm looking for a plsql package in order to perform basic operations with ip adresses and subnet masks like:
- validating an ip address (dot format)
- converting masks (16 -->> 255.255.0.0)
- splitting an ip range with a higher subnet mask (10.3.0.0/16 -->> 10.3.0.0/17, 10.3.128.0/17)
It's very difficult to find any information about this on google so if you know or had written such a package or function....As using BITAND function
with two arguments IP_ADDRESS (transfer 32bits-integer) and
POWER(2,32)-POWER(2,32-MASKS),
you must be able to get ip range (32-bits-integer)
and a higher subnet mask by IP_RANGE+TRUNC(POWER(2,31-MASKS)).
And then you can transfer it to dot format (decimal,octal etc.) easily. -
My ipad mini 3 is not showing that it is connected to the wifi, but it is saying it is not connected to the internet. I have reset network settings and then reset all settings and it has not worked. I have tried to change it to static and change the IP address and the subnet mask and that is not working either. I have also tried to use the wifi in different places and that doesn't work either. Please help!!!! iPad is useless without the internet.
1. Set router back to Auto DHCP.
2. Turn off router for 30 seconds and on again.
3. Re-boot iPad. -

On my home wireless network, the iphone 5 won't let me enter the IP address, subnet mask and router info. I was able to enter the DNS and Search Domains. How do I open up those fields?
Apparently the router is not sending the info to the iphone. How can I make that happen?

How to change IP address and subnet mask without using the sys-unconfig ?
I have Solaris 10 x86. I've ran into problems using the sys-unconfig command
to change hostname and IP address.
How to I manually change the IP address and subnet mask values on Solaris 10 manually?
Thanks.We just switched over a DNS server by using ifconfig, (same subnet), and killing named. seems to be working fine, anything I should look out for ?
steps:
Prep -
- change name in /etc/hostname.e1000g0
- change name and IP in /etc/hosts and /etc/nodename
- # uname -S dnsint02
Activate
- unplug old dnsint02
# ifconfig e1000g0 192.168.2.80
# kill -9 [PID of named]
Cleanup
- Remove old key on clients I SSH from.
- reconfigure backup software for new name/server combo.

How to configure the eth1 port of NIcRIO 9024 to another IP address and subnet mask
Hi ,
I am using cRIO 9024 and am planning to configure it to be an MMS server that interacts with a client which is in another network with different IP and subnetmask. I want to run the server VIs from the host computer via the eth0 port and want to communicate the MMS messages through the eth1 port. the eth0 port is configured as a static IP as shown in the screenshot attached and would like to assign a separate IP and subnet mask to the other port . But when I try to save the configuration I get the error "Could not save your changes tot he target.The subnet mask for eth1 is invalid" .
I have already directly cross connected the Crio and have disabled the firewalls and still am not able to configure it.
1) is it possible to configure the ethernet ports to have separate IPs corresponding to different networks and thus the subnet masks?
2) If its possible then what is the mistake i am doing while configuring it ?
I would be extremaly grateful to have a reply on this as its pretty desperate to spend a lot of time just to set up the IP configurations..!!!!!
Regards
AbhinavDear Abhinav,
I'm sorry but what you are tryining to do is not suported by the Second Ethrnet Port on any cRIO and so you getting this error meeage.
Here a abstract out ouf the KnowledgeBase How do I Configure the Dual Ethernet Ports on Real-Time Controllers?:
Ethernet port 2 is currently not supported to communicate outside its own subnet. There is no capability of configuring the Default Gateway for Ethernet port 2 and therefore cannot connect to a large isolated intranet. However, there appears to be a common misconception that this port can only be used for communication between NI products: this is not the case, though any communication through the secondary port must be within the same subnet.

Weird IP address & subnet mask
Just got a new 24" Intel imac -
Copied settings during set-up from old imac - but in network settings a different subnet & IP address which are not my Lan settings keeps coming up and I can't connect.
I tried manually configuring the settings - still doesn't see the router - I have entered the router address correctly and even reserved a static ip for new machine but no joy.
Anyone else encountered this? Any suggestions?FYI this is the discussion area for the much older iMac G4.
You should post your question in the Intel-based iMac discussion area. -
Subnet mask 255.255.255.255 assigned to VPN client - can't ping LAN
Hi,
I configured PIX 501 with PPTP VPN to connect to the small office (PIX FW, Win 2000 Server, several Win clients, LAN IP 10.0.0.X/24):
ip local pool mypool 10.0.0.101-10.0.0.105
vpdn group mygroup accept dialin pptp
vpdn group mygroup ppp authentication mschap
vpdn group mygroup ppp encryption mppe 128 required
vpdn group mygroup client configuration address local mypool
vpdn group mygroup client configuration dns 10.0.0.15
vpdn group mygroup pptp echo 60
vpdn group mygroup client authentication local
vpdn username xxxx password *********
vpdn enable outside
I can connect to the office using Win VPN client, but I can't ping any hosts in the office network. I suspect that the reason for that is subnet mask assigned to the VPN client: 255.255.255.255. ipconfig of the VPN client:
PPP adapter Office:
Connection-specific DNS Suffix . :
IP Address. . . . . . . . . . . . : 10.0.0.101
Subnet Mask . . . . . . . . . . . : 255.255.255.255
Default Gateway . . . . . . . . . :
Default GW is missing too, but I think this is not the main problem.
Any way, what is wrong with my config? How to fix subnet mask assigned to clients? Or may be my assumption is wrong and this mask is ok? What is wrong then?
Any input will be greatly appreciated!
GeorgeThanks for the prompt reply.

There are remnants of old config, I just recently took over this network, some lines look odd to me, but I did not touch what works. VPN config is all mine.
PIX internal 10.0.0.23 - is a gateway for the network. DNS server in LAN - 10.0.0.15.
I've been reading about the problem and came across several posts that this subnet mask is normal, but it puzzles me - how can this host communicate with anyone else if there is no room for other hosts in this network (according to the mask)?!
Thanks again!
