Cannot Access Internet With Some Device Only?
Aug 20, 2012
I am currently experiencing trubles with my WiFi network. I have used it just fine for past two years with laptop and iPod Touch 4G, but I am unable to connect my newly built PC to the Internet.I've used Asus WiFi Go adapter at first because I thought that it's just a hardware problem with it, so I decided to buy TP-LINK TL-WN722N adapter, which has same issues, I can access everything on the local network (LAN), but I can't access the internet, however Windows reports it is connected to the internet. The router I am using is TP-LINK TL-WR340GD.

MGMcc solved my set up problem with my KDL-32ex713 which (i've swapped for a new model - its a long story). I used exactly the same ip addresses for the set up on this KDL-373x524 and got messages "wireless device found, local access failed, internet access failed". As my router and pc are the same as last time why the set up doesn't work this time and what I should do?

My WRT310N linksys wireless router has recently stopped permitting internet access to devices connected to it, both wired and wirelessly. I have connected my broadband modem directly to a single computer (which is how I am posting this) and evidently there is nothing wrong with my internet service. I have tried restarting my modem, the router, and the computers I am trying to access the internet with, and it has not worked. Note that local communications work fine, I was able to ping another device connected to the router, and even establish a TCP connection.It is possible that the settings on the router have been changed without my knowledge, if so, however, I do not know which setting could be causing this.

I just purchased a WAG54G2, setup was simple and easy. After being on for about 16 hours if I login to the device all the settings appear to have been reset to default, although the access point and wireless are still working. After another few hours the internet access stops and device appears to have been reset. No power spikes or reliability problems with power. Contacted Linksys support on three different occasions and they don't have any suggestions that work. Tried a "hard reset" but problem still occurs. No firmware upgrades are available for this device.

I am working with a device that does not have a physical reset button on it, and have mistakenly typed in 127.x.x.127 for it's IP. I was trying to use 172, but mistyped and didn't catch it until after I had rebooted the unit. Is there anyway that I might be able to gain access to the device. My PC is running Windows 7, but I am familiar with linux as well. I have attempted to change the loopback adapter IP to 128 on a ubuntu live disc and set my ethernet port to the subnet the device is on with no avail. (I am also using vlans on the device, but believe I have them set up correctly)the device is set to IP: 127.x.x.127 netmask 255.255.255.128. [code] I know that the last octet of 127 is the broadcast IP for the range, but have been able to address similar blunders before by forcing myself to a /24 subnet to correct that.

I am trying to share a printer on Windows Server 2003 machine so that my other computers can access the print share from my server. originally i was hosting the print server from one of the workstations (running Windows XP SP2). I now want the printer share to be hosted from the server. I set up the printer correctly (to my knowledge). i was able to set it up and print a test page. But when i go into properties and attempt to share the printer, i click on Share this Printer and enter in a name, i designate it to list the printer in the directory. Then i click apply and ok... and nothing happens. the printer is not shared. When i go back into properties, it shows that i am not sharing the printer.

I currently have a BT Home Hub 3 router and an Ubiquiti Power AP N. What I am trying to do is use the Ubiquiti access point as the main device for all connections in my house (ethernet and wireless) so that I can use the QoS settings etc. I basically want the Home Hub router to play as little role as possible in the network except for providing the ADSL internet connection. How would I be able to do this?I know I need to enable DHCP on the access point but everytime I do so the devices connected to the access point lose internet connection.(BTW I have an ethernet cable connected from one of the routers LAN ports into the access point's WAN port)

I have a new audio/video receiver that has Apple Airplay functionality built in. Now the Airplay allows any Iphone/pod/pad/tunes device/computer on the same network to route music to the receiver without plugging in the device directly. Great concept but the execution allows any computer or iphone in my house on the network to take over my receiver with no questions asked and start playing.
So far I have failed to find a way to restrict or shut off Airplay on the device itself (other than disabling it's network). If there is anyway through networking or my DIR-655 router to control/restrict this access? What I would like in a perfect world is to keep all computers and wireless Apple I devices from connecting to the unit unless I allow it for that particular device/computer. In an imperfect world I would accept just blocking wireless devices from it but still allowing them full network connectivity otherwise.Some things I have thought of - Can I use static addressing for the A/V receiver but put it on a different subnet then what my router is set to? Is there some network control in the firewall that may limit access to the A/V receiver?

We are using ACS ver 4.2 and trying to setup users with limited access to our switchs and routers. Here is what we did:
1) Created a user in ACS
2) Create Shell command Autorization Set - ReadOnly
Unmatched Commands - Deny
Commands Added
show
exit
* this should limit the user to the show and exit command only (correct)?
3) Created a group - HelpDesk with the following TACACS+ Settings
Shell (exec) is checked
Priviledge level is check with 15 as the assigned level
Assign a Shell Command Authorization Set for any network device - selected
ReadOnly - shell command autorization set seleted
When the user logs on to the router/switch it appears that he has full access. He can enter the enable command, config terminal command, etc. All we want him to be able to do is to issue the show command.

I have a question reguarding the Cisco Secure ACS 5.2 and network access vs device admin access. We have our switches,routers,and firewall configured to use TACACS+. We also have configured our Wireless LAN Controller to use RADIUS for allowing for 802.1X authentication to the wireless network. We are using Active Directory for the backend user database and have assigned the users to different groups in AD. We have a Network Admins group to access the network devices and a Wireless Users to access the WLAN. The problem that we have is that everyone in the Wireless Users group can access the devices and run full commands on them. We want to limit the Wireless Users group from being able to do this. Is there a policy or config change that we will need to make for this?

My client has a PC that can use a SIM card to gain access to the internet. They have an ASA5540 and are running IPsec VPN.
When accessing the VPN while the PC connects to the internet via use of the SIM card, he connects successfully to the VPN but is unable to access anything on the internal network. If he connects to the internet using wireless or wired, he connects successfully to the VPN and is able to access everything on the internal network.
Is this a limitation of the Cisco VPN Client? Perhaps something missing in the configuration? Or do they still require the mobility license (though I thought that was only for AnyConnect)?

I have a computer running Windows Vista that has been unable to access the internet, either with wireless or cable. It just says that no connections are available.Troubleshoot doesn't detect any problems.I also realized that I cannot access device manager, nor can I add/uninstall anything. When trying to get into device manager, I get " the specified service does not exist as an installed device".

I have 4 DAP-1522's bridging to a WNDR3700v2. Any device plugged into any of the 1522's can access the internet and can access shared drives etc. on any other device plugged into any 1522. I can access the WNDR3700 admin website from a device connected to a 1522.
However, no device plugged into a 1522 can access a device plugged into the 3700's ethernet switch. Likewise, the devices plugged into the 3700 cannot access devices plugged into 1522s.
Devices plugged into the 3700's switch can access the internet and can access each other.
I have changed network cables, power cycled all devices (PCs, bridges, routers, etc) at least once. I am running latest firmware on 1522's and 3700. In short, I've tried just about all the basic stuff.
It almost appears that the 3700's switch is acting as an isolated network. I would say that were true, except that I can access the router admin page from anywhere (any 1522 and directly connected to the 3700).
All devices are within the 10.0.0.x address range with a subnet mask of 255.255.255.0. Again, I have no problems accessing the internet. Just the problem of devices plugged into a 1522 communicating with devices plugged into the 3700 and vice versa.

I have a mail archiver (hardware device) in my network that I need to access to from the Ipad/iphone. There is an app for it but I have to allow the access on the ASA. I created an 'object' for the device and added a Static NAT entry for it, then added an access rule. Its not working so I am guessing I did it wrong. The device uses port 8000 which I also added to the object. correct commands, or using the ASDM works too.

I have been asked to allow our employees to connect their own devices to a open wireless network. I want to control access to preauthorized devices and I am looking for solutions. We do to have access to any other control devices like an ACS and I would like to archive the result using just the 5508 controller.

I am new to ACS 5.1.I need to configure the ACS to act as the 802.1x authentication Server, as well as, act as the Radius Server for the authentication and authorization process when I access the switch.
I had created Two rules (under the Access policy) to cater for the two scenario, it will always "stuck" at the 1st rule. For e.g. Rule-1 is meant for the 802.1x, Rule 2 is meant for the AAA process. When I tested with 802.1x, it worked perfectly. But when I tested to login to the switch, it always failed. Based on the log, Rule1 is not able to fulfill my requirement (of course it can't). I thought the rules check process will proceed with Rule-2, but apparently it did not.

I've got a WAP610N access point and 4 WET610N to connect to it - however, no matter what I do when trying to install the WAP610N the setup tells me it cannot find the device.I've got the WAP610N connected to a homegateway (SAGEM) and my computer connected wired to the HGW. The HGW is setup as a DHCP server, everything beside the WAP610N works. It gets an IP address, and I can login to the web interface of the access point - but is still unable to use the setup and unable to connect any of the WET610N.

Is it possible with the E2500 (or some other device) to rebroadcast a wireless signal?Here's the situation, I live on a boat, I want to connect my laptop to a local wireless signal (which I pay for). I then want to connect my E2500 to the laptop via the "Internet" port on the E2500. This doesn't work? This would allow all my wireless devices to stay connected to a single connection point. When I move the boat and change the wireless connection, I only have to do it once for a single connection. Is there some way to achieve this?

I'm running an ISE 1.1.1 and i need to authenticate guest users.The goal is apply different Authorization profile to the same guest user based on the thevice he use to connect to the guest wlan.
I.E.:
if guest user "user1" connect to the guest WLAN using a windows laptop, than apply "Guest" authorization profile
if guest user "user1" connect to the guest WLAN using an Apple iPad, than apply "Mobile" authorization profile
I've tried to deployed the following 2 authorization policy:
1)if "Apple-Device" and "IdentityGroup:Name EQUALS Guest" then "Mobile"
2)if "Guest" then "Guest"
but the first rule never match and even if I use and iPad to access the guest network the "Guest" authorization Profile is matched
I've verified that the iPad is correctly recognized as an Apple-Device changing for test purposes the rule table in
1)if "Apple-Device" then "Mobile"
2)if "Guest" then "Guest"

I have several AP's of 1131 AG used in autonomous mode. Recently one of them stops responding: i was not able to access web management or ping its NIC. I've tried with reseting device to default but no success, even more when i plug ethernet cable to AP port nothing happens even NIC led's are not blinking at all.
On CLI console i am seeing repeated constantly such entries:
*Mar 1 05:19:04.086: %LINK-3-UPDOWN: Interface BVI1, changed state to up
*Mar 1 05:19:05.086: %LINEPROTO-5-UPDOWN: Line protocol on Interface BVI1, changed state to up
[Code].....
( i have new firmware but how to upload it without this interface running ? )

I have a WAP54g set up as a repeater. It even shows in the WRT54g device list (Tomato firmware) as a WDS interface but nothing can connect to it. I have the repeater's MAC address in the AP and it's set to "Access Point + WDS" mode. I don't know what I could be doing wrong. Is it a conflict of DHCP on the AP vs static on the repeater?

Within the Internet Access Policy section of the browser based utility, is it possible to limit access for a specific device (PC) to LAN only (not allow any traffic to external internet)? I see that you can block internet access for a specific machine, however I didn't know if this was inclusive of LAN as well.If not, is there another way to achieve this via the E3000 or should I be looking for a solution on the specific PC itself?

I am having trouble connecting my device to certain WiFi networks. We work with hotels and we have a handful of devices that are just not able to connect to their network. Te device works fine in my office. When I get to the Setup page and do a site survey, it'll get to 100% and then display a "page can't be found" as oppose to showing me that it has been connected. We had the MAC address cleared in their network and still no luck. Firmware has also been updated.

Internet: Comcast
Modem: D-Link DCM202
Router: D-Link DIR-655
Scenario: An alternative router was temporarily swapped into my network. After reconnecting the old equipment only network device is able to connect to the internet. My computer, the only device with access to the internet, seems to automatically resolve a Comcast IP, but all other devices obtain an address in the 192 range. Setting the IP address statically to the 192 range kills connectivity. The router continuously tries to obtain the IP information from the modem, but never does.

I'm configuring a console server for configuring remote devices. This is working well except for the fact that if a target device is in ROMMON mode, the console server refuses to displays the target device console. It does open the connection but the ROMMON prompt is not shown on the console server . This is essential for this device as we will need to use it to reset passwords remotely and thus need to be able to access ROMMON mode from the console server.
Parts used are a 2951 router and a HWIC-8A serial card. Posted my config below:

Current configuration : 4389 bytes

My BEFSR81 is my primary router and has DHCP turned on. The router's DHCP range is set to accommodate 12 devices. I have three computers wired to it and their Host names (as specified in the set-up of each computer) show up in the router's DHCP device table. I also have two printers (one old Brother HL5250DN laser printer and one new HP Photosmart Premier C410a inkjet printer) connected and there are blanks where the Host name should go. I would like to be able to tell which printer is which when I am looking at the DHCP device table. How can I get a names associated with each printer's IP address in the router's DHCP device table? (The real problem is that the router seems to have both printers at the same IP address (192.168.1.100) and if I can get one of them to change I'd like to know which one it was!)

We are using LMS 3.2.1 with SP1 and Campus Manager 5.2.2.Server runs Windows 2003 R2.Everything runs fine except for User Tracking on two Catalyst 6500 switches running CatOS. These devices are discovered, reachable, SNMP works fine, neighbors seen. But when we try to launch acquisition, the UT utility complains with this error message:"Failed to start acquisition: Device unreachable. Please enter a valid device."When we wanted to add ports via Device Trap Configuration, LMS has fired a different error message: "There are no ports to configure for the selected device(s).Check whether you have selected any router(s)." I have checked the portsData.xml file, which doesn't have any ports included for the two devices: [code] We have tried to exclude / include the switches in the data collection, but that didn't work.
