Computers can't see each other after installing E3000

I've found several previous posts regarding my issue, but none of them have led me to a solution to my problem. Here is my problem. I have a small home network that I was able to share file and printers on, now I puchased and install a Cisco E3000 and my computers can no longer see each other. My current configurations is as such: I use DSL and have a 2 wire DSL modem with wireless capabilities. This particular modem has a port for the phone line and a port for local ethernet. I've taken the local ethernet and plugged in the internet port of the E3000. All computers can reach the internet but they cannot see each other. I've verified that file and print sharing is enabled on all computers. In fact if I remove the E3000 from the configuration and place them back onto the 2wire wireless connection they see each other. So I'm pretty certain that the firewall software on each PC will allow file and printer sharing. So that leads me to believe that my problem is in the E3000. It is perhaps blocking the network discovery protocol or something. Does anyone have any ideas how I can resolve this problem? Any help is appreciated.
Solved!
Go to Solution.

Thanks Showguy82 that seems to have worked by allowing my computers on the network to appear under network tap in windows explorer. However I'm still not able to access the computers. Something is being blocked by the E3000 because I completely disabled the fire wall on my PCs and still couldn't access them. Do you perhaps know what should be changed in the E3000 to allow access to the computers. Thanks for your help.

Computers can't see each other

I posted this first in the iTunes area, because I was trying to figure out how to make Home Sharing work, but my troubleshooting is leading me to believe I have a networking / Time Capsule issue instead of an iTunes problems. Here's the situation as I was trying to get Home Sharing working between two Macs:
Both computers are running latest Snow Leopard version. (10.6.3)
Both computers have firewall OFF.
Both computers have file sharing ON.
Both computers connected to the same wireless (dual) network managed by Time Capsule (computer 1 is "g" computer 2 is "n")
Using Terminal to ping computer 1 (10.0.1.6) from computer 2 (10.0.1.4) results in timeouts.
Using Terminal to ping computer 2 from computer 1 results in timeouts.
Now engage Computer 3
Using latest version of Leopard (10.5.8)
Firewall OFF.
File Sharing ON
Connected to same Time Capsule, ("n").
Using Terminal, Computer 3 (10.0.1.8) can successfully ping both computer 1 and computer 2.
So, my Leopard machine can talk to both Snow Leopard machines successfully, but neither Snow Leopard machine can talk to each other. HUH???
Anybody got any ideas?

Never got an answer or resolved the problem. I'm calling it "answered" just to clear out my unresolved questions folder.

Computers can't see each other on E3000

I am using a E3000 behind an ATT Uverse router. Every computer can connect to the internet. E3000 is used as DHCP and ATT Uverse is DNS. With this setup, computers can ping each other's IP address but can't use computer names. When names are resolved, ATT Uverse doesn't know IP address assigned by E3000 router so host is unreachable.
This is an issue since I can no longer share or backup files between computers in my home.
I have tried to use another router as a DHCP and DNS but then every computer uses the new router as the default internet gateway instead of the E3000 to the ATT Uverse router. It seems the heart of the matter is that E3000 doesn't have DNS capabilities and can't use a simple router for both the DNS and DHCP functions while retaining default internet gateway function.
ANy suggestions?

I did all that. I can ping all computers as long as I use their IP address. It's definitely a name resolution problem.
My solution is that I disabled DHCP on the E3000 and made it a bridge on the Uverse network. Now, Uverse gives out the IP addresses via DHCP, tracks the name/IP relationship and resolves DNS for the Intranet. DNS for the Internet is solved by the network via the Uverse router. Now, I can ping IP addresses or names and get good responses.
As far as I know, each computer cannot track the Name/IP relationship for other computers on the same private network so I don't understand your comment 'handled by the operating system.'

2 Mac can not see each other via airdrop under the same airport/timecapsule.

I have 2 iMac in my home with a TImeCapsule (gen4).
The wifi is on both 2.4G and 5G with the same SSID.
iMac A is working on 2.4GHz, iMac B is working on 5GHz.
So they can not see each other via airdrop, meanwhile they can see each other in the left panel of Finder.app
Is it a known issue of AirDrop?

Hi Kirby Zhou,
Welcome to the Apple Support Communities!
It sounds like you would like to utilize file sharing between computers, not necessarily AirDrop. Please refer to the attached article for information on the file sharing process. If this is not what you are looking for, please let me know.

Can't see each other on network after installed OS 10.9.3

After i installed OS 10.9.3 on all of my Mac stations, they can't see any of the Mac anymore. The network router works fine, but they just won't see each other. I found these problem after install OS 10.9.3 to 2 of my Mac Pro. They can't connect to the Macbook Pro runing lower version of OS 10.9.2. Please help.

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, by a peripheral device, by a font conflict, or by corruption of the file system or of certain system caches.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards, if applicable. Start up in safe mode and log in to the account with the problem. You must hold down the shift key twice: once when you turn on the computer, and again when you log in.
Note: If FileVault is enabled, or if a firmware password is set, or if the startup volume is a Fusion Drive or a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to start up and run than normal, with limited graphics performance, and some things won’t work at all, including sound output and Wi-Fi on certain models. The next normal startup may also be somewhat slow.
The login screen appears even if you usually login automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin.
Test while in safe mode. Same problem?
After testing, restart as usual (not in safe mode) and verify that you still have the problem. Post the results of the test.

Computers on network can't see each other and can't communicate

I have a Linksys router, WRT54G, which calls itself wireless but has only wired connections.   I have my computer and my phone (for Vonage service) plugged into it.    My router is then connected to the household router by a CAT 5 cable.   The household router is also a Linksys; wireless and with plugs for a half dozen computers.
I get teh Internet fine with no problem, but we want to share my printer on the household network.   My housemate cannot see me on the household network and can't see my router either, and can't communicate with my computer with the \\Name command.   I can't see the household network and can't communicate with my housemate's computer with the \\Name command.
I am running Windows Firewall.   I am sure that so is my housemate.
Is there something special we have to do to set up our routers for the household network to work properly?
It looks like I'm supposed to configure my router to communicate with another router instead of connect directly to the Internet, but when I tried htat and enabled interactive adjusting or whatever I suddenly couldn't access the Intenet and my phone couldn't get a dial tone, until I changed it back.
Tehre isn't any explanation of how to do it anywhere.   There aer technical descriptions of what each thing does but I don't see where it says how to set it up or how to troubleshoot.
I don't know if we were supposed to set up networks and manually add each other's computers. Apparently my housemate did not have to do that with his wife's computer or his notebook.    They just show up in the network.
Yours,
Dora

Thanks for your help.   Unfortunately between when I last looked at your name and when I managed to reply I forgot your name.
1. For the option that the parts of the network can see each other, you plug the cable into the OUTGOING port of the SECONDARY router?    That doesn't make a whole lot of sense; how cuold that possibly work? The way I understand it, the signal can come in only through the incoming plug, which you call the "internet" plug, if I'm understanding you.
2. If you choose the setup that makes any sense - the cable is plugged into the incoming plug - the "internet" plug - on the secondary router, and the ethernet connection on the primary router, can all the computers see each other and their resources, ie, printers they want to share?
3. If not, why on earth?
4. for the second option, it looks like some steps are missing.   Why don't you need to disable DHCP and set the router to be a secondary router?
PM me for my contact details.
Thanks!
Yours,
Dora Smith

Can get onto Internet but Computers don't see each other

I've got my Linksys connected via ethernet to a desktop - using DSL. Security enabled. Had my network set up fine - a wireless laptop sees the intenet connection and the computers saw each other fine (shared disks, etc.)... Today, my DSL went down for a bit - I jumped onto my neighbor's open wireless. My DSL came back up. THe desktop and laptop both see the internet. But they don't see each other any more. I've run those stupid wizards ten times. I've tried creating a new workgroup. They can ping each other. I don't get it. HELP!

When changing settings for file/printer sharing on Windows it is always necessary to be patient. The whole workgroup browsing concept of windows requires some time to be up to date. I suggest you run the sharing wizard ones and follow the instructions there exactly.
Also try to ping the other computers to see if anything goes through.
As you have "jumped" to your neighbor's network for a moment also make sure you connect to the correct network. Better remove the neighbor's network from your list of preferred networks. Else you end up there accidentally.
Therefore, you should better setup the sharing while all computers are wired to the router.
Another possible cause could be the firewall on the computer. Make sure to turn it off to see if it is the problem. Most software firewalls (except the windows firewall) react very sensitive when you just 'jump' to another network and tend to block all traffic by default.Message Edited by gv on 02-09-200701:58 PM

Computers can't find each other with home sharing

My home sharing has worked before but now I can't get my two computers to "see" each other. I have tried just about everything. Any helpful hints?

Mac or PC...?
My first suggestion would be to check that the firewall on your router has the correct port/s open.
Then i would switch off home sharing on both machines, reboot both and set up again.

IMac and Macbook can't see each other via Airp

Except sometimes.
Using Leopard on both new machines, I can share Internet connections and printers fine. The problem is in trying to mount volumes or share files.
I create a network on the iMac, connect to it on the Macbook, and use the appropriate password on both machines. I've set file sharing preferences perfectly and confirmed that at the store.
Sometimes, from the Go menu I can find one machine from the other. Sometimes I can't. When I find them, file sharing and accessing work fine--although for some reason, the volumes do not mount on my desktop! I have to use the Go Network menu item.
But other times they just don't see each other. I only get this to work by REPEATEDLY logging out of networks, turning Airport on and off, creating new network names, and so forth.
The worst results come from creating a familiar network with a name and password I've used before. The best results come from creating a brand new network, new name and pswd. And creating the using 128-bit WEP is the worst, but I think that sometimes that works, too.
My question is, am I doing something wrong, or is this another Leopard/Airport bug?
Also, if I can access the other computer in Go Network, how come the volume doesn't mount on my desktop??
Thanks.

Don't know if this will help - but if you're using an Extreme base station go to the Airport Utility and look at the list of DHCP Clients. I had the same problem only I had an iMac and a Macbook running OS 10.4.11. Turns out that my printer and my iMac were sharing the same IP address. When I assigned a permanent address to the printer (out of the normal distribution range used for the other computers) the problems all went away. So, for instance, if the router was assigning IP addresses ending in 10.0.1.199, 198, 197, etc., and the primary computer ended witih 200, I named the printer 10.0.1.201
Hope that helps.

Computers don't see each other on home network.

Recently set-up a wireless network. Using a linksys wrt54gs. A DSL modem is tied into this and desktop is hard wired into router. I also have two other laptops using the router wirelessly. The problem: All computers see the router and connect to the internet, but I can't seem to get them to see each other for file sharing and printer sharing from desktop. My wireless network has a name, and the workgroup for each computer a different name from the wireless network, but all the same.
Desktop is XP, (1) laptop is NT, and the other is Vista.
I not a PC guru and probably a liitle over my head so any help would be greatly appreciated.

I went home that night and done the same with AVG antivirus. Can't believe it was as simple as that.
configure your antivirus software like AVG or Norton to allow file and printer sharing as well as allowing your windows firewall to do the same.
Mine was in AVG firewall > settings (or Configure) > system > file and printer sharing......................just click on the dropdown box to allow.
As soon as I done this I went to my network places and the network files were visable.
other settings in there also solved my remote desktop problems.
Why couldn't I have thought of this 6 months ago.

My iMac and MacBook can't see each other on the same wifi network

I've got a 2010 MacBook running Snow Leopard and a late 2009 iMac running Lion. They are connected wirelessly to a Belkin N+ router and can ping one another by IP. They can also share a mouse using Synergy by IP. They can't resolve one another's hostnames (<compname>.local).
Unfortunately, they don't show up in each other's local network in Finder. They have recognized each other twice in the few days I've had this set up but those times were directly after a reboot of both machines and even then, only one machine could see the other. One time it was iMac -> MacBook, the other it was MacBook -> iMac.

More information: After restarting my router and upgrading the firmware, the my MacBook was able to see my iMac (ping it directly immediately) and it showed up in the list of Shared devices.
My iMac was able to ping the MacBook eventually (after 22 timeouts, it eventually got a few high round-trip pings that lowered shortly thereafter), but it is still unable to see the MacBook in the Shared devices list.
I was, however, able to mount it with Finder > Connect to Server > afp://192.168.2.3. This is useful progress, but it's not ideal because I use some software like "teleport" that still doesn't recognize my MacBook is a shared Mac. The teleport software on my MacBook does recognize the iMac as a shared Mac.
Here's the output for my attempted ping from the iMac to the MacBook:

2 Macs sharing an external hard drive, but can't see each other's music

We bought a 300GB Lacie external hard drive, and pointed each Mac's iTunes to the same folder on that drive. Then the computer asked to "consolidate," which means copying all the music on each to that shared folder--which is great so far. But then in iTunes one Mac can only see the music it copied to that folder, and the other can only see the music it copied over. If I go into Finder, I can see both of our music, but in iTunes, no. There is some purchased iTunes music, but mostly just our own CDs.
What happened, and what can I do? Thanks!

Each computer (actually, each user account on each computer) has its own iTunes Library, which is a directory file. Moving computer A's music files to the new hard drive resulted in the Library file being updated to show the new location of the music that already was part of the Library. Moving computer B's files to that same location didn't affect computer A's iTunes Library file.
On each computer, you'll need to use the Add to Library command (or do the equivalent by dragging music folders from the Finder onto the Library icon in the Source panel of iTunes) to get all the music into your Libraries.
If the Copy files to iTunes Music Folder when adding to Library preference is ON (under Advanced\General of iTunes Preferences), then when you add music to your library, those files will be copied to the location in iTunes Music Folder location, if they're not already there. You may want to check these settings to make sure you won't end up with extra copies of music files in locations you hadn't intended.

My computers don't see each other on the network

my Imac (early'06) and a machine running Ubuntu (apparently a linux platform OS) and a windows machine are connected to the same network thru a router. All machines access the internet fine. However i want to file share with the other computers but they dont show up in my network window.
also when i type their IP addresses into Connect to Server dialogue, I cant connect to them or even see them on a network.
Anybody familiar with setting up cross platform networks?

Has Ubuntu and Windows ever seen each other?
You say "Ubuntu is apparently a linux platform...". not apparently - it IS a linux platform (are these your computers?)
The first thing is to get them all into the same logical Workgroup.
On PC: ControlPanel>System>ComputerName..jot down workgroupName.
On ubuntu, the file/etc/samba/smb.conf is edited (might not need this yet).
On Mac: Utilities> DirectoryAccess, Configure SMB/CFS...enter WorkgroupName in appropriate box.
(then look into SystemPreferences>Sharing, and turn on File Sharing.
In network utilities on the mac, have you been able to you ping these computers by their IP address? Have you been able to ping mac by number from Windows or Linux?
This site might help, too along with the Apple link that the other user posted:

Two Macs can't see each other on same network

We have an iMac and a Mac Book Pro on the same apple network at home. The iMac can see and connect to the Pro and exchange files but the Pro can't see the iMac in Go > Network. All sharing settings are the same. Any thoughts welcomed.

How many machines are on your network? If you have over 7, then here should be an entry called "All..." in Shared in the Sidebar. Click on that. It will show you all the servers that are available on your network. You can also get to this list via Computer (Command-Shift-C) and click on Network.
Shared in the sidebar shows a max of 7 servers, with Back To My Mac's at the top (if any), then servers you have mounted share points on (if any), then the top 7 (in alphabetical order) servers in Network (a.k.a. "All...").
Hope that helps.

Mac Mini and MacBook can't 'see' each other on the network

I have an 'old' Mac Mini set up to the Airport Extreme base station via ethernet cable and can happily connect to the internet. I also have a MacBook that connects wirelessly to the AEBS. A couple of things frustrate me..
Although I can connect to the internet from the Mini the Airport Utility can rarely find the base station so any diagnostics are impossible.
Also, the two macs are unable to find each other over the network. Both have personal file sharing turned on in the prefs. Occasionally the MacBook identifies my Mini on the network but when I try and connect (clicking on the alias) i get the "the alias XXX's computer could not be opened, because the original item cannot be found".
This is frustrating as I would like to share/copy files over the network.
Is there something simple I am missing?

A couple of things to check.
The Mini will need to have file sharing turned on.
And the appropriate holes in its firewall set.
It should be assigned its IP number by DHCP.
It should not be plugged into the WAN port on the
AEBSn.
Using Terminal (on the mini)
You should be able to PING the other computer,
And you should be able PING a computer on the
internet.
ie. apple.com
Hi
File sharing is on and firewall is off. As I mentioned I have connection to the internet and can ping apple.com. It is not plugged into the WAN port on the AEBSn - the modem is plugged in there. The IP is assigned by DHCP
I can ping the macbook (when the alias is in Finder) but I get a "connection failed...server may not exist or it is not operational at this time. Check the server name or IP address and try again" when I try to connect.
