C7-00 wifi subnet mask changes automatically

Hi,
I am facing a problem in my c7 that it wifi subnet mask is changing automatically even if i set it manually.
thanks

no open apps ...
I did a bit of testing today and discovered, that the connection doesn't close, only when I exit OVI Store (this happens with WLAN and also with 3G/UMTS connection).
When I exit any other app (e.g. Browser, Opera, ...) the connection closes automatically after I have closed down the app.
So this must have something to do with the OVI Store, probably with the new version as I cannot remember to have experienced this until some days ago.

Presentationser won't start after subnet-mask change

After changing the subnet mask (in order to be able to connect to the server remotely), the 'Oracle BI Presentation Server' service (sawsvc) will not start anymore.
Eventlog shows: The Oracle BI Presentation Server service terminated with service-specific error 4294967295 (0xFFFFFFFF).
Can anyone help me out, what I have to alter, in order to make things work again?
After updating the host file I am able to connect to the database, so sqlplus and OBIEE administrator work. It is analytics that will not run anymore because of the service that will not start.
thank you for any help you can give,
Jeroen

Thanks for letting the community know.
The behavior described is usually related to issues with the startup files used to boot Windows. However, this could be one of the outliers.
HP units are usually pretty good about detecting incompatible memory and won't get as far as it is getting.
In the mean time, it certainly wouldn't hurt to try the steps listed while waiting for them to arrive.

Wlc 5508 webauth subnet mask change issue

Recenly l changed the network subnet for a particular wlc interface and scope and also an upstream router and for some reason it would only allow me to use a /24 Host mask as my plan was to go to a /22 mask to allow for over 1000 hosts within this scope.
The Upstream Router which is a ( RV042 ) had the following original config :
     192.168.1.1
     255.255.255.0
I have noticed this device will not let me change the mask from a /24 to a /22 as you can only change from a pre-defined list of masks and you cannot manually add any either..
New Config
     10.10.0.10
     255.255.255.0
WLC 5508 Controller Interface
     Original Config
      192.168.1.25
     255.255.255.0
     192.168.1.1
     New Config
     10.10.0.25
     255.255.252.0
     Scope
     Range : 10.10.1.10 - 10.10.3.254
     Mask : 255.255.252.0
     Network : 10.0.0.0
     Router : 10.10.0.10
When l reconfigure to this addressing the wireless clients connect and get the new dhcp scope details but following this the webauth screen doesn't appear not allowing them to connect meaning there is no routing of traffic / internet access.
If l modify the above interface and scope masks back to a /24 - 255.255.255.0 the the wireless clients connect and webauth appears to prompt them to accept the terms and conditions and connect thus giving them internet access.
It looks like an issue with the mask ? The main reason l am trying to change the subnet addressing is because the standard /24 mask is not providing enough dhcp addresses and we have had times were the scope has been exhausted due to the public connecting and disconnecting as the lease perod of 2 hours holds onto the address before expiring meaning there is not enough available addresses for people to connect.
I would of thought that the upstream router ( RV042 ) even though it is only a /24 mask would still route the traffic coming from a WLC Controller interface with a /22 mask ?
Hopefully someone can suggest a solution ?
Thanks Simon

Hey Scott just getting back to this issue..   If for instance l can modify the wlc interface and Scope to have a /22 mask ( 1022 Hosts ) and my upstream Router ( Cisco RV042 ) can only provide a /24 or higher mask then does that mean l am still limited to a range of 254 hosts ( /24 Mask ) ? Would this mean l need to look into replacing my upstream Cisco RV042 VPN Router ?

Ipad is showing connected to wifi but it is saying its not connected to internet. I have reset all settings, tried to change IP address and subnet mask and nothing is working.

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.

Leopard wifi issue: subnet mask?

I have the common Leopard wifi problem:
4 computers, all linked to new Airport Extreme with 10.4
3 of 4 link with Leopard.
Have tried all suggestions to fix the problem with the IMac G5 that won't link.
Always says that the iMac has self-assigned IP and can not connect
Noted that when the problematic machine does rarely link, Subnet Mask is 255.255.255.0
Same with all linking machines.
When doesn't link, subnet mask is 255.255.0.0.
Does this give any hint as to the problem.

This might not be related, but you could try changing the DNS settings in your Router to use OpenDNS instead of the number automatically set by your ISP. You just need to manually enter the 2 numbers:
208.67.222.222
208.67.220.220
There are good instructions on the OpenDNS website. It's worth trying just to see if it solves your problem:

Why would Airport change subnet mask?

Hello all.. kinda new to this stuff and was looking around for an answer, but couldn't find my exact situation. So, forgive me if I ask some stupid questions... Ok, I have MacBook Pro, and recently had to do a reset on my modem/router, and now this particular computer won't connect wirelessly. I also have a macbook air, and connects fine wirelessly. It seems I have narrowed it down to the subnet mask... maybe, but not completely sure. Just to be clear, I don't have the Airport express, I am just simply talking about the airport function built in to connect to a wireless network (not sure if it's called something different, or is the one on the actual computer just called airport?). So, going into the airport utility does nothing for me. It can't find any wireless devices. And everything I have read has been talking about going into that program and changing things. Anyways, I tried connecting automatically (using DHCP) and manually, but nothing helps. My macbook air gets a subnet mask of 255.255.255.0, while it has now started giving my macbook pro a 255.255.0.0. And I'm assuming my router is still configured for 255.255.255.0, but now my computer isn't.. How is that possible? Just wondering if anyone knew why this was happening and/or how I can fix it. Like I said, I'm not a genius with this stuff, but any help would be appreciated. Thanks for your help! And if I have missed any important information, let me know..

Unless you have an Apple-brand Wi-Fi base station, AirPort Utility is of no use to you.
It might help to reset the connection settings on your MacBook Pro using these steps one at a time until the problem is resolved, recognizing that, depending on your problem, not all of these steps will make sense:
1) Use the AirPort menu bar item to turn AirPort off, then on again.
2) Try to select your Wi-Fi network from the AirPort menu.
3) In the Network panel of System Preferences delete the AirPort item from the left column, then add it back.
4) In the same panel as (3), define a new location and see if you can make that work.
5) In the same panel, select the AirPort connection item, click the "Advanced" button, select the "TCP/IP" tab, then click "Renew DHCP Lease". Note that the fix this step implements may be temporary.
6) In the folder /Library/Preferences ( _not_ <yourhomefolder>/Library/Preferences), move the folder SystemConfiguration onto the Desktop, then restart your computer. See if you can now make your AirPort connection work.
These steps may not help, but they'll only take a couple of minutes to try. Before you try these, if you have any special network settings on your Mac for things like DSL credentials, note all your network settings, because the latter steps will destroy them. If you got all the way to the last step, if things don't work any worse than before, you can trash the saved SystemConfiguration folder.

Change IP-number and Subnet-mask with LabView?

To upgrade the software on a CRio-System, the user needs to change some settings in the TCP/IP-configuration.
To simplify this task I think on a possiblity to do (and at the end redo) the changes in the TCP/IP-Configuration of the Windows PC.
What I need is:
- Change the IP-Adress (from "Obtain IP adress automatic" to IP xyz...)
- Change subnet-mask
- Redo this settings by saving an existing config or set to "Obtain IP adress automatic"
Who knows if and how it's possible to do that in LabVIEW?
Perhaps I have to call a script /.bat-file?
LabVIEW 6,7 and 8 available :-)

I have used this for a program that needs to have a host IP address for High sped cameras. I have it change the IP address to the required address and change it back when I am done. Here is a very simple Labview version of this code with out the switch back.

HT1218 I'm trying to set up a new iPad..it asks for my WiFi network.. I find the network..then it asks for information that I have no idea about: IP address, Subnet Mask, Routet, DNS, Search Domains, Client ID..also the headings are: DHCP,BootP, Static..c

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 wifi network connection is not working, will read "unable to join". Am able to access as a guest. When I hit the blue arrow on the right hand side of my network there is no information e.g ip address, subnet mask, etc. This info is in my guest area.

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
- Reset network settings: Settings>General>Reset>Reset Network Settings
- iOS: Troubleshooting Wi-Fi networks and connections
- iOS: Recommended settings for Wi-Fi routers and access points
- Restore from backup. See:
iOS: How to back up
- Restore to factory settings/new iOS device.
- Make an appointment at the Genius Bar of an Apple store.

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.

Ip address & subnet mask !

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)?

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.

Linksys WRT54GL - illegal subnet mask message

Hello everybody,
I just changed the ISP and the new one is on optic fiber, and they arrived with theirs equipment, wich is a Huawey EchoLife HG856 and I connected it to my Linksys WRT54GL.
When I tried to configure the router with the settings gived by the provider i received the following message:
"illegal subnet mask".
The setting given to me by the provider are: (i replaced some numbers with *, for privacy)
Where is the problem?
adresa de IP: 1**.27.1*4.6
netmask: 255.255.255.128
gateway: 1**.27.1*4.1
DNS1: 1**.2*1.2*2.1
DNS2: 2**.1*4.1*4.1

Try to hard-reset the router for 1 minute,power cycle the router and check again.

Defining VPN Subnet Mask?

Howdy,
Ok this problem occurs on Windows Vista, and is, to my knowledge classed as a bug, as it never occured on XP. So when I migrated over to OS X I assumed it would not be there... I was wrong, cos it is!
I connect to several VPNs to access MySQL DB's, and I use these everyday and are very important. Now a few of the VPN's use a subnet mask of 255.255.255.0, like most connections. Now the other VPNs use a subnet mask of 255.255.240.0, and when connecting to these VPN's OS X just assumes the subnet is 255.255.255.0 and therefore, even though it connects fine, I cannot access anything on this server cos of this problem!
Now the only way, to my knowledge, around this is to run the ifconfig command to get my assigned IP Address, then run the command:
sudo route add -net 192.168.16.0 192.168.16.* 255.255.240.0
Where * represents the last 1/2 digits of my assigned IP address. This does work, but is quite frustrating, just as it was running the "route" command on Vista.
Does anyone know of a way around this? So I can tell OS X to add me a subnet mask of 255.255.240.0? Or even a way in OS X to automatically run the above command via terminal when I connect?
Any help will be appreciated!

Steve M

Do you know how I can join my office domain via the PPTP connection? I've triend both the QuickVPN client as well as, Windows built-in VPN connection. I've only been able to successfully connect using Windows VPN connection. I could not get QuickVPN client to work.
