Problems of connectivity with R-2621xm, S-2950

Hello, I have a 2621xm router and a Fa 2950 (24 ports) switch. I have a problem for the WAN switch outside, when I run a ping test when you are connected to the cable on the router console, it works fine. DHCP works very well for VLANs and I can ping other Vlans on the switch. I can ping the router via the switch, when it is connected to the console of the switch port, I cannot ping anything. In addition, the router get assigned an IP through my cable modem. Any advice would be much appreciated. It is just a laboratory at home but has been a learning experience!

Below are the files of the running-config:

The default gateway on the switch must be 10.1.5.1.  Make the 2950 transparent vtp in order to see what VLAN is created int e config itself.   Check that all them VLAN on the 2950 are created using show vlan.  Get rid of the address on the vlan 1 just so it is not confused, even if it is stopped.   Maybe this might help.  Check your acl believe the way you have it, it will match only to what in the 10.0.0.0 won't one of your addresses in 10.1. Try to put your inside nat statements on your subinterfaces for each subnet. Add instructions to your acl to include all your subnets not only 10.0.0.0.

  • Can not solve the problems of connection with Wifi (Intel Centrino Advanced - N 6205) card

    The card Wifi on my X 220 (Intel Centrino Advanced - N 6205) gave me so much trouble, I'm about to give up on this and buy another laptop.

    In general, the connection to any hotspot Wifi in any location is quite unreliable. It looks like it is connected for a while.

    And several times a day, sometimes several times per hour, I have to go to the Intel Wifi connection utility and click "Repair" to force the card to renew the IP address. This resets the connection and run for awhile again until I do more.

    In recent weeks, I tried everything I could think of. I uninstalled the drivers, installed the latest drivers from the Lenovo Web site, then tried those on the Intel site. Those who are a little more reliable, but the problem persists.

    If the drivers of card/can't be fixed, is there a chance to get Wifi to work again if I buy another Wifi card and install it? Should which card I try? Can be installed without sending it to Lenovo?

    Any help or ideas is greatly appreciated. Thank you!


  • Power Save Polling (PSP) leads to problems in connection with some access points

    Symptoms:
    The following symptoms may be seen if an access point Wi - Fi (AP) or router Wi - Fi broadband does not properly support the Power Save Polling (PSP) feature:

    These symptoms may be more pronounced when on battery.

    Cause:
    The PSP mode is a feature that provides the long battery life for laptops. It requires coordination between the AP or router and the Wi - Fi adapter. Intel has discovered that some APs or routers may not implement the feature correctly or completely.

    Socorro

    Heard different things people try, depending on their wireless adapter.

    Start, control panel, device, netowrk, their adapter, power management Manager. Clear the checkbox to allow windows to turn off this device to save power

    Start, control panel, device, netowrk, their adapter, advanced management. Looking for antenna diversity. Some cards have it and others don't. Replace the Auto antenna by supply diversity

    Some have disabled Wireless N of their card and achieved good results.

    Some Wireless N adapters operate ONLY on the 2.4 GHz frequency.

    Using these parameters of the recommended wireless router I use channel 11, have GREAT results. I usually recommend creating a new SSID to make the connection easier. Wireless devices also needs to connect to the NEW network.

  • Connection with the Apple ID server problem

    iCloud on my ASUS ZENBOOK can not connect.  It always returns a connection error message: there is A PROBLEM CONNECTING WITH THE APPLE ID SERVER.

    My laptop is an ASUS model UX303L (64-bit) running Windows 10 Home, Version 1511.

    Key points:

    (1) I have connected to my very well through several iPhones iCloud account, multiple iPads, an iMac and another ZBOX PC running the same version of Windows 10.  (Confirms that it is not a problem of "User" with me trying to use the wrong password).

    (2) from my laptop problem, I can connect to the internet fine iCloud - Chrome and Firefox version by.

    (3) I have the latest version of iTunes on the laptop, which starts very well and logs in my iTunes store (.. .in the Australia).  [This is interesting, because I guess that both iTunes and iCloud connect to the same server Apple ID to check the details].

    (4) I made sure that Windows is completely up to date, and that my office 2013 is also entirely up-to-date, with a full stop/restart of the laptop to make sure that nothing is installed in half.

    (5) I uninstalled iCloudand reinstalled from a new download.  Did not help.

    (6) before the iCloud upgrade to the latest version there is + 2 weeks (I'm now on the 5.2.1.69 Version), iCloud worked perfectly, including the good synchronization of Outlook calendar and favorite contacts on different browsers.  I want to try and reinstall the old version - see if that restores me to my nirvana earlier, but I couldn't find anyway to do.

    Suggestions as to best 'next steps', I can take would be highly appreciated...

  • Connectivity with AT & T-Motorola 3360 and Airport Extreme problems

    Bought a new extreme-Airport (7.7.3) to replace my old AE after 9 years of service.  The installation procedure, but could not get the airport to connect with my modem (Motorola 3360).  Called at & T and they crossed put me the modem in Bridge mode and which seemed to work.  But only temporarily (about 5 hours).  Restart the modem and the airport was not working.  Troubleshooting I tried to plug my MacBook directly into the modem, but even the computer couldn't get an internet connection.  Another call to AT & T and they reconfigure the modem to their end.  After 90 minutes and try everything they could, they have finally admitted defeat and told me that they could not solve the problem.

    However, after a fairly exhaustive search of this forum, seems to be two issues that many people is with Airport extreme.  One is that the modem (in this case a Motorola 3360) is perhaps not fully compatible with the airport.  The AT & T support person was not aware of this until I asked about it, so she did a quick search and was rather surprised to see that there is a lot of people having problems with the Motorola Modem.  She told me that they use no more Motorola modems but ship the 6200 of Netgear.  "All know issues?", I asked.  She sought and, to his surprise, even once, there was.

    So, first question.  Does anyone know a modem that is compatible with the airport or use one that they had to limit problems with?

    The second question prevailing seems to be with the IPv6 protocol.  Anyone know if there are problems with the AT & T IPv6 protocol and the most extreme airport?  I did not disable IPv6 yet to see if that helps.  I thought I'd ask here first.  Couldn't find anything on the AT & T site.

    When I return from the road (great place to go to get away from technology) I will make a new round of full power of all the components and try Setup again from scratch.

    Any ideas or suggestions would be greatly appreciated.  Miss all know profanity.

    Thank you.

    Any other relevant information: 6.3.1 the utility Airport, Airport Extreme 7.7.3, MacBook Pro running 10.8.4, modem Motorola 3360, AT & T high speed DSL, shoe size 11-1/2 wide.

    When you have configured the 3360 as a 'bridge', this would mean that the AirPort Extreme should then be put in place to provide the PPPoE connection service. The airports are not known for their reliability in this type of installation... no matter the type of modem that you can select, so I drop this method as a connection option.

    If you want to keep the 3360... and you have time to experiment... then you can set the 3360 to its original default settings and configure the router from the airport most convenient to connect using DHCP in router Mode of DHCP and NAT.  That will produce what is called a message Double NAT, but maybe it's not of concern on a simple home network, and Apple provides you with the option 'Ignore' the Double NAT, so the airport will display a green light instead a light orange blinking slow.

    You need to try this configuration for a few days to see if the Double NAT will be a problem or not, because it is not possible to predict the effect of a Double NAT on a network... you have to test a few days see how things behave.  If this configuration works well, for you, then you can leave it as what.

    Please note that I do not recommend this type of installation, just suggesting it as an option this work could , if you want to keep the 3360.

    How Double NAT affect IPv6, I can't tell, since I did not use att for several years, and I'm not familiar with their implementation. On wired, IPv6 works fine on the airport with Comcast and Time Warner.  We can provide these parameters for you if want, but have no idea how well... (or if)... they will work with ATT.

    If the installation of Double NAT does not work, your best option would be to go there and get a modem/router or gateway to ATT device and then set up the most convenient airport in Bridge Mode works correctly with the modem/router ATT.  You will turn on the routing of ATT function in this type of installation, but the airport can also produce a signal from the wireless network that you can use.  The modem/router ATT will also provide a wireless signal that you could use for guests, or disable the feature, if you do not need two wireless networks.

    This may also be the best option if you want to configure IPv6 as IPv6 of ATT service must be compatible with the modems/routers and gateways.

  • Internet connectivity with iOS 9.3 problems

    I have an iPhone handset 6

    Since the update the handset does not connect to the internet.

    Indeed, despite a complete network redefined and, when the connection through wifi to my router at home and tries to access the internet - no luck!

    IPhone 6 combined - still on the old version - disorder web access my wife.

    I can only put it down to the upgrade and the information circulating on the net about similar issues.

    The iTunes doesn't seem to recognize that there is a more recent patch for the 9.3 iOS version 13E233. Some sites there indicate iTunes should detect a fix updated since this original version. I saw the reference to 13E234.

    Help, please. Frustrating that *!

    iOS updates regularly change of variables operating system which, from time to time, will affect negatively other parameters and the features of the component on the device (including WiFi).  In addition, this can be a problem with your carrier and the specifics of your plan data or of the SIM card in your device settings that need to be addressed or refreshed.  To update the carrier settings, place a call to your carrier and place them on your device.

    This particular issue on the side of the Apple of street connectivity has been surfacing regarding the update and its been mainly a question of the environment such as WiFi access or your router (s) your help, I've had this as well and here are the most effective steps, I can give you to solve.

    WiFi/Internet environment

    1 restart your router

    2. check the latest version of the firmware on the router (router manufacturer and manual will have instructions on this one)

    Apple IDevice

    3. remove the WiFi access point of your iDevice which is the blue tick, if its power to establish at least a connection with your internet facing router it is a very practical and viable step to achieve. Settings > WiFi > * WiFi Access Point name * > forget this network (another option is to simply renew the lease, which will be used in blue at the bottom of this screen) my recommendation is to forget this network and let your iDevice and the router to build a new pile of access point.

    4. (optional if nothing above has solved the problem on this point) reset network setting on your iDevice, you will probably need to provide credentials for your router here.  Settings > general > reset > reset network settings > restart

    5. last resort to restore your device using iTunes, using iTunes on your Mac or PC to restore the iPhone, iPad or iPod to factory - Apple Support

    It is a fairly complete set of instructions to identify it's a software or a configuration issue with your device.  If after that you had accomplished each of these steps, the problem is not resolved, move to consider a repair like the WiFi hardware physically in the device may be damaged.

  • HP Pavilion Notebook-15-p108tx: problem connecting with specific programs

    Hi, I had problems connecting with specific programs recently. I'm still able to communicate online through web browsers. Mozilla Firefox works fine, but Google Chrome still has some problems loading of specific pages or they don't load at all. The main programs I am having difficulties with are mainly games platform programs like Steam, Battle.net, and League of Legends, and I'm unable to go online or to connect to their servers.

    I never had no problem connecting like these last two years that I've owned my laptop, until recently. I think it was the 6th or 7th of may these problems started.

    I updated my drivers and was constantly check to download the most recent. I don't know if it's my internet provider, but I was also constantly check the State of the network to ensure that the services are very good.

    If anyone else has this problem and if there are any suggestions that you think could help solve this problem, it would be appreciated.

    Thank you

    Hi Jasper,.

    Thank you for the update. I think that your computer have a rootkit infection. Most of them were inside of the Chrome Extensions.

    Here's what you need to do.

    Open chrome

    Click on the Menu bar in the upper right

    Click more tools

    Click Extensions

    Please search for suspicious extensions that does not belong to the computer, especially ads. Once you identified, simply click the trash can icon then Chrome close then reopen it again to see if you can connect to your desired game. If this isn't the case, then proceed as follows.

    Manual removal of suspicious files (if you are uncomfortable with it. If this is not the case, then run System Restore from safe mode with command prompt)

    Manual removal (I miss the old days of MS virus removal )

    Go to RUN type %temp% , and then delete all folders by pressing SHIFT + DELETE

    Go to Control Panel and then locate all the apps that you think a form of ads

    Go to safe mode with network. Run Malwarebytes in that State

    Then run Tweaking tool to fix everything that has changed since your computer

    http://www.Tweaking.com/files/setups/Tweaking.com_windows_repair_aio_setup.exe

    If your not comfortable with the troubleshooting steps may perform the system restore on the day, it was working fine.
