Blocking a computer in wireless network

I have a wireless network in my restaurant so all the guest can surf the net for free.
I also have my business desktop computer that uses the same internet access with wire.
how can I block the wireless users from this computer, so it's invisible and not accessible to them ?
Thanks,
Yuval

Sorry, but the suggestion posted by Ricewind is not correct. Setting the IP of the second (wired) router to 192.168.1.2 will place it on the same subnet as the wireless router, and will provide no security between the wireless and wired router.
Please connect your system the way I described in my previous post.
The only setting that is required is to set the "Local IP address" of the wired router to 192.168.2.1 . Also, you must make sure that a LAN port on the wireless router is connected to the Internet port of the wired router.
Just as the Internet port of your router protects you from hackers on the Internet, so too will the Internet port of the wired router protect you from wireless hackers at your business. The Internet port is designed to ignore all unrequested data that arrives at the port, making it very hard for any hacker to break in.
Even in the two router setup, it is probably best, in the wireless router, to set "AP isolation" to "enabled". This assumes that you will not be connecting a printer to the wireless router for your customers to use. By setting "AP isolation" to "enabled", it will help protect your customers from hacking into each other's computers.

Trying to reconnect an XP computer to wireless network.

Have an XP computer that was previously using my Time Capsule--wireless network. The XP had to be recovered with recovery discs b/c of virus. Since the recovery I can't use the wireless network on that computer. The network appears in the list but when I try to connect I get a message that tells me Windows is unable to connect to the selected network. Network may no longer be in range (which it is..all bars are green) refresh and try again. Any suggestions?

The TC does not conform to SMB network standards.
Change the name so it has no spaces and is pure alphanumeric..both TC name and wireless name. I also recommend manually setting to N and set channels manually.
If you do not get full ip address and gateway plus dns or the values are wrong, make sure you have downloaded the very latest driver from the wireless card manufacturer.. ie if Intel download the driver direct from Intel.. also you need to be on SP3 with all the updates.

Photosmart C7280 will not print from one computer on wireless network

C7280 will not print from desktop computer via a home wireless network. It has worked in the past, but ceased recently.
It will print from a laptop on the same network.
I have tried to comply with the procedures on the HP Support and Drivers site, such as the HPHNDU.exe routine and others, but have had no success.
I would appreciate some help. My previous post in May has not had any replies.

Connecting to Windows Computer via wireless network (Password issue)

I have a wireless network set up at my house, and we all can see each other's shared computers, and the windows machines can connect to each other without a problem.. but my Mac cannot connect to them, but they can connect to me. When I goto "Connect to Server" it asks me for a username and password for the windows machine.. I don't know what to do from here!!! Please help, thanks a bunch

In your Sharing panel, did you go into "Options" and check the box for sharing via SMB?
Then from XP you should be able to reach the Mac via //(ip# or DNS name)/
and you should see the available shares.

Officejet 7500A Wide Format printer connects intermittently to computer through wireless network

I have a recently purchased Officejet 7500A printer that I would like to use wirelessly. I have an Apple wireless router and am running Windows 7 on my computer. The printer and computers individually connect to the network and there are no issues with the router. The issue is with the connection between the computer and printer. I can print things from my computer by emailing the file to the printer, but only sometimes does it work through directly printing from the software. I have tried to scan from my computer and from the printer, but get the same error message from both that there is no communication between the printer and computer. I suspect it is a firewall issue, but am not sure how to modify the settings to allow this communication to occur. I have the windows firewall and have Advanced System Protector software, but have disabled the windows shield in that software. Help?

So do you have multiple anti-virus systems installed on your PC (even if they are not all active)? If so, this can certainly lead to bizarre behavior.
I would pick one system, uninstall others using their own unistallers (restarting the PC after every uninstall).
With the one you chose to have on your system, make sure it is updated to the latest rev.

Can't connect to computer through wireless network

I recently purchased a Powerbook G4 with OS X Server 10.4.6 installed, and I cannot connect to my iMac G5, which has OS X 10.4.6 installed. I am trying to connect them wirelessly, and it sees the G5, but tells me that it is offline and can't connect when I try. I can connect to the Powerbook through the iMac, but not the other way around. Tried different share settings on G4, but am quite unfamiliar with OS X Server. Any help would be appreciated.
Thanks.

It seems like you may not have the relevant service(s) enabled in Sharing preferences on your iMac, if I understand your problem correctly. The settings on the server, other than firewall, shouldn't matter for outgoing connections.

Printer no longer working after wireless network reset

OfficeJet Pro 8500A, MacBook Pro, running Mavericks.
Since 3 days ago, when we re-added a password and locked our wireless router (ATT modem, UVerse), our printer is "off-line" Print jobs queue up, but do not print. When I go in and check it says "printer off-line." Or in the print queue, it is something like "looking for printer."
It worked briefly when we found a cord and plugged it in to the laptop, but will not work wirelessly, which it was doing before. No changes except to re-do password for the network.
I have the manual and have turned everything off, then back on in the order recommened (router, then printer, then laptop). Still off-line. Can someone please help? Thank you!

Hello @LindaGrace,
Welcome tot he HP Support Forums!
I understand that since re-adding a password to your wireless router your HP Officejet Pro 8500A e-All-in-One Printer is not communicating wirelessly with your Mac OS X 10.9 computer. I would like to assist you today with resolving this wireless communication issue.
Now, making a change to your network, such as a adding a password or altering a password, results in having to reconfigure your printer on the wireless network. At this point your printer is being 'blocked' access to your wireless network due to the change that you made. To correct this issue you simply rerun the wireless setup for your printer to 'tell' the printer the network name and password. Once the wireless setup is run successfully everything will continue working for you as per normal.
To run the Wireless Setup Wizard on your printer please follow the steps below.
On the printer touch screen, touch the Right Arrow () to display the second navigation screen.
Touch Network () to open the Network Menu screen.
Touch Wireless.
Touch Wireless Setup Wizard, and then touch Continue.
Wait while the printer searches for routers that are within range. The Select Network (SSID) menu displays.
Scroll down the list of network names until you find the name of your network.
Touch the name of your network.
If prompted, enter the WEP or WPA key. This is the password for your wireless. The password is case sensitive.
Wait for the printer to connect to the network
- Source
Once your printer is connected to your network again, please try to print. If printing still fails you may need to re-add the printer to your Mac because of the printers new network connection. Please follow the steps below to add the printer back to the Mac.
1. Click the Apple menu, and then click System Preferences.
2. Click Print & Scan, and then check if the name of your printer displays in the Printers list.
3. If your printer is already listed, remove and re-add the printer to confirm communication with the Mac. Click the name of your printer, click the minus sign (), and then delete the printer
4. Click the plus sign (), click Add Printer or Scanner, click the name of your printer
5. Click Add to add the printer to the list.
Now that the printer is successfully configured on your network and added to the Mac please try wirelessly printing again.
Please respond to this post with the result of your troubleshooting. Good luck!

How to block one of wireless network

Hi there,
I have Airport Extreme with 2 wireless networks, one for my iMac and my wife’s iPad another one is for kids PCs. All of us are connected only wireless.
Question, how shall I block the kids network my configuration, now when I block the Airport (Turn Off Airport) actually it’s only me who cannot use wireless network, all others still can do it. Purpose is to block the kids using the wireless network during the night. Now my solution is to pull out lan cable between Airport and ADSL modem.
I believe there must be smarter way to do it, I just don’t know how. Could you please help,
thanks

Hello!
Your Extreme can set time restrictions on when specific computers can access the network. You can configure them using AirPort Utility:
Open AirPort Utility, select your Extreme in the sidebar, and press "Manual Setup." If you're asked for a password, enter it. Go to the "Access Control" tab and set "MAC Address Access Control" to "Timed Access."
Now you can set up the time restrictions.
To add a computer to the list, press the "+" button. You'll be presented with a dialog that will let you configure the time restrictions. You'll need to enter the device's MAC address. You'll also want to enter a description so that you'll know what device the restriction applies to.
You can double-click the "(default)" entry to set restrictions on computers not on your list. When you're finished, press "Update" and allow your Extreme to restart.

Neighbor's wireless network not secured, anyway to block it?

Hi guys,
I'm using road runner and have parental control so that I can monitor my kids using the internet. The problem I have is that one of my neighbor's Linksys wireless network is not secured and my kids are using it to play on line games, you tube, etc. and stay up late at night and not doing home work. Anyway that I can block his signal? Like to have your opinion about this situation. Thank you and any help will be greatly appreciated.
Message Edited by ono8ono on 10-21-2008 01:32 AM

Well, then either lock down the computers of your children, take them away during night. Even if you convinced the last person to secure his wireless network you would still have to tell everyone to use WPA2 or WPA with a strong passphrase. WEP is easily cracked within a few minutes with tools readily available. Plus, if you see eight wireless networks broadcasting their SSID you probably have a few more not broadcasting the SSID, a couple of them will probably be open or WEP secured, too.
And then, once you have them all convinced to use WPA you must constantly monitor the environment for new wireless routers.
So basically, for most people trying to block their children through the router or even through the computer is futile. Children have far better resources at hand to tackle any problem you may cause them limiting internet. The only really reliable way to do this is the good old way of limiting access to the computer/device. Just like TV. Far more reliable, far more secure, far easier to implement, far easier to understand.
If you thought so far that a high tech computer and a high tech router should be able to do high tech things to keep your children out: computers are still dumb devices and no match to a teenager desperate enough.

How do I use a wired computer on the wireless network?

I want to hardwire my desktop to my wireless router. I have a wireless adapter and my computers work fine on the wireless network. If I try to plug in the ethernet cable to the router and disable the wireless adapter, it doesn't work. The light lights up on the front of the router saying that the ethernet cable is plugged in and the 1394 network connection is enabled in the "network connections." However, I cannot ping the router when using the ethernet. On the desktop computer, I look in "view workgroup computers" and there are no computers listed there. On the back of the computer, there is a light that lights up when I insert the cable, so I know the computer has detected there is a cable plugged in there.
They way I set up my wireless network is by using XP's tool under network tasks called "set up a wireless network for a home or small office" (which is found in "My Network Places." I don't know how to combine a wireless network with a wired network. Please help me.
I am using WRT54G. We don't have broadband installed yet.

Correct…I would not mess w/ the bios. Do you have an extra cat5 cable long enough to plug into the back of your router to the back of your PC? Hopefully, it was not taken out when the wireless NIC was installed. Do you see a place to plug in the cable on the back of your PC? It looks like a phone connection jack/ modem, only bigger. If not, what kind of machine, OS (Win 2K, Win XP, etc).

Need help here! I'm out of options. Computer can't see the wireless network

Sorry for the novel, but I have to tell you what is going on with my computer. I also need to vent because I’m extremely frustrated. I want to make sure I give as much info as I can we can get this fixed. I’m done with trying to figure this out on my own!!!
I’m having a major issue with the wireless network connection on my desktop. I’ve tried everything and I can’t figure out what it’s doing.
First of all, my wireless router is set up correctly (according to the Sticky), has active security, and works fine. It has nothing to do with the router. I’m sure of it.
Here’s a quick history:
When I was at my first residence in Chicago and bought a Linksys wireless N router in May 2008. My computer was about 30 feet away from the router and everything worked fine. Always found the router and never lost connection.
I moved to a new place in September 2008 and used the same router, computer, etc. at my new place. The computer was only about 7 feet away from the router this time, but I used the wireless connection instead so I wouldn’t have a network cable lying across the floor. At first everything worked fine. No issues. Then, one day out of the blue, my desktop lost connection with the router. My router didn’t even appear as an Available Wireless Network. I rebooted everything and that seemed to fix it. OK, issue fixed, right? Wrong. It did it again the next day. I rebooted everything, but it still couldn’t find my router. It did see lots of other wireless routers in the area though so I know the wireless card was working. It just didn’t see my router.
This went on for a while. Sometimes it would see my router and connect then it would lose it again. I thought maybe it was the router going bad. Well, I have a notebook computer too so I tried it. It has found my router every time and has never lost connection. I had it sitting on top of my desktop even to see if there was some sort of dead spot in my condo, but the notebook found my router just fine.
Sometimes my desktop would see my router, but it wouldn’t be my network name. It would call it “Home” or something. I know it was my network because it was the only network with maximum (Excellent) signal strength. I’m thinking it must be some sort of association issue. For some reason it doesn’t associate my router as an available network. I don’t understand that.
I tried everything: Ad Aware, Live OneCare, registry cleaners, driver updates, restore points, pretty much anything I found in the forums. Nothing worked for long if at all. It’s like my desktop only finds my router when it wants to. Note: The only thing that would work sometimes was if I clicked “Repair.” Sometimes that would work. I finally gave up and connected my desktop via network cable and unhooked my wireless card. I never lost connection as long as it was hard-wired.
The drama continues. I recently moved to Iowa and set up my network here. I’m using the same router, same desktop and wireless card, same notebook computer, etc. I went ahead and tried the wireless card on my desktop again. It worked just fine! No connection issues at all. It connected and stayed connected. I thought, “Well, that’s strange. It must have been something with the condo in Chicago. Oh well!” It worked fine from February 5 until March 10. Now it’s doing it again!!!! The notebook is about 3 feet away and sees the router just fine.
Here are the facts:
I’m using a Linksys WRT300N Wireless-N router.
I’m using a Linksys Wireless-N PCI WMP300N Adapter (about 18 months old).
I’m running Windows XP on the custom built desktop and Windows Vista on the HP notebook.
I built this computer about 5 years ago and have not done any major upgrades for 2-3 years. The only thing I added was the wireless card. I also changed out the HD in January 2009 and did a data migration right before I moved to Iowa in February. All of the networking issues were going on well before I did the data migration though so it has nothing to do with that. In fact, I had my computer hard-wired into my router at the time of the data migration and the wireless worked fine (for a little while) after I moved to Iowa. So if anything, the data migration seemed to help with my wireless connection.
All drivers are up to date.
Using Windows Live OneCare and have run complete scan: nothing found.
Using Ad Aware and have run complete scan: only found cookies and deleted them but didn’t fix issue.
Ran WinsockxpFix but that didn’t help.
Ran TweakNow RegCleaner Standard but that didn’t help.
Right-clicking the wireless icon, I try to view Available Wireless Networks. The window comes up and shows me other wireless networks in the area (2 available right now), but doesn’t show my network at all. I click “Refresh network list” and 1 or 2 of the other networks will come up, but mine is still not shown.
I’ve clicked “Repair” and get this message: “Windows could not finish repairing the problem because the following action cannot be completed: Connecting to the wireless network.”
If I go to Control Panel, there is a Wireless Configuration Utility program from Broadcom. When I open that here is what I find:
It is not managing my wireless networks.
Under the “Wireless Networks” tab I see my Network with an “X” over the router icon to the left of it and a locked security icon to the right of it.
No information under the “Link Status” or “Statistics” tabs.
The “Site Monitor” tab shows my wireless network and the other 2 networks in the area (although they drop in and out because of signal strength). My network is always present even though the signal strength bounces up and down. This tab shows that my network is secure, 802.11 is g and n, speed is 270 mbps, Channel is 9, and Signal bounces from orange/red to green. Data encryption is (m)TKIP, TKIP, WPA-PSK.
I was going to use my notebook to post this message since it has been connected for 2 days without ever losing connection. It shows Very Good signal strength and is about 3 feet away from my desktop.
Update: My desktop just connected to my network after sitting there for 2 hours. Good to Very Good signal. Broadcom tool shows the connection and now has information in the Link Status and Statistics tabs.
Cancel that. It just lost connection again. It was only connected for about 5 minutes. There is no change in signal strength according to Broadcom though. In fact, Broadcom shows better signal now that I lost connection.
Now, it just connected again (on its own) after sitting there for 10 minutes! I’ve been surfing the web on my desktop for 45 minutes now and I’m using my desktop to post this message. What the heck?!!! This is what it’s like. Aggravating huh?
Well, that’s all I can think to write. What else do you need? Can anybody help me with this?
I’m confused. Please help!
Thanks a lot!!!

Thanks but it's just my desktop that doesn't see it though. My notebook sees it everytime, even at the same exact time that my desktop doesn't see it. For example yesterday when I was typing up this post, I was typing up the post on my notebook because my desktop didn't see the router. I don't think it has anything to do with the router actually, but I wanted to see if anyone on here has encountered this issue before. Other forums have similar issues but I've tried all of the fixes I found elsewhere and they didn't work.
Any other ideas?
Thanks!

I have a canon scanner MP560 wireless. Needed to create new wireless network and now my computer can't find the scanner/fax..

My iMac doesnt' see my Canon MP560 wi fi scanner ever since I created a wireless network in my house. Can't find a way to change whatever settings i need to to connect the scanner. help.

Well let's see if we can help you get set up. Have you got any 2.4 GHz cordless phones in the house and if so try unplugging them and do a hard reset of the express.
1. unplug the express
2. press the reset button
3. while pressing the reset button plug in the base station
4. keep holding the rest button till you see 4 green lights flash
you may have to hold it for 30 seconds or so
if this doesn't work try plugging the express in right beside the computer and then going through the airport setup assistant
Good luck

Hello there @Rico6952 , welcome back!
I read about how your printer is not finding your wireless network and I wanted to stop in to see if I could help you. I have some suggestions that I would recommend for you to hopefully help. Check the links out below. They are all related to network connection problems.

Maybe. What kind of other computer are you talking about? What operating system is it running? What kind of wireless router are you using?
Your best bet may be to just reset the router and set it up again.
Just so you know, WEP is a very old security system for wireless and is considered insecure. If you have it available, use WPA2.

My Epson XP - 400 will not print wirelessly or via USB. The documents just sits in the print queue while the computer is "searching for the printer". I set up the printer on the computer and it is connected to the wireless network.

I'm unable to print wirelessly or connected via USB with my Epson XP-400. The computer continues to say it's searching for the printer even though the printer is set up on the computer, the printer is connected to the wireless network and the USB is plugged into the computer.
