    VPN problem

    Hi Mate, Make sure your Phase 2 security association timers are matching on both ends.

    Should VoIP effect internet bandwith?

    Hi mate rule of thumb. 100kbs up/down for each active phone call. Keep in mind other traffic on this network may effect VOIP call quality if all bandwidth is consumed. (Use QOS to mitigate if possible)

    Random Internet Dropage

    Step 1 isolate the issue. Is the problem your internal LAN or internet related. Open up two instances of command prompt. In one of them add command. ping 8.8.8.8 -t The other ping your router internal ip address. example: ping 192.168.1.254 -t This leave a continuous ping running to an internal address and an external address. When the drop out next occurs alt tab and take a look at the ping results. if 8.8.8.8 stops working, internet is down if gateway is no longer reachable from your PC to your router is down. Start out here and we can isolate problem to your PC or your internet connection.

    DNS Server not responding

    What makes you 100% sure the problem is your DNS server? easiest way to rule out internet connection issue vs DNS issue. If you can ping 8.8.8.8, but you cant ping google.com. This would indicate DNS fault. If you cant ping both your internet is likely down. If the problem is 100% DNS related. Try change the DNS server in your NIC settings to 8.8.8.8 (Google public DNS) Your first step is to isolate the problem. Then we can work out a fix for it.

    Ethernet Cable not working

    Do as Nene says, If the problem is isolated to your PC next try: - Is the windows DHCP service started? In command prompt sc query dhcp You should see the state as running: (See below) SERVICE_NAME: dhcp TYPE : 30 WIN32 STATE : 4 RUNNING (STOPPABLE, NOT_PAUSABLE, ACCEPTS_SHUTDOWN) WIN32_EXIT_CODE : 0 (0x0) SERVICE_EXIT_CODE : 0 (0x0) CHECKPOINT : 0x0 WAIT_HINT : 0x0 - Try reset all your windows networking to default 1. Run CMD as admin 2. execute command: netsh winsock reset

    extreme networks 400-24t MGMT Light blinking???

    From memory, all the ports are disabled by default or can be in the startup wizard. I think it varies depending on Model ahvent worked on Extreme in a few years. Either way. If this is a bone stock no config switch running EXOS the management port should obtain an IP address VIA DHCP. Connect the OOB management port to your LAN and look for the lease. Try telnet to the IP address. If this has already been configured you might be able to get this by inspecting ARP requests using wireshark on your PC. Login creds are: admin / nothing by default. Once in run command enable ports all If you still have trouble, you will need. USB to serial and correct serial cable to diagnose the fault at the CLI. Cheers Shannon

    Ethernet Cable not working

    Run command: ipconfig /all in command prompt and send output. Sounds like DHCP is not working on your network. In ipconfig output. If your IP address is within range 169.254.X.X, DHCP is outright just not working which could be for a number of reasons. If your IP address is within 10.X.X.X or 192.168.X.X. Check the IPv4 gateway field in the ipconfig output. Make sure this is your Routers IP address. If not you could have a rogue DHCP server on your network. Could be new WiFi access point on your network? ping 8.8.8.8 do you get a response? If you do and internet is down your DNS server is broken or not reachable. Try ping google.com. If this fails but pinging direct IP works, set a static DNS server in your NIC IPv4 settings 8.8.8.8 which would confirm if your DNS is failing. ping you default gateway, do you get a response? Command Prompt Example: ping 192.168.1.254 Request time out means its not working. run arp -a output. Make sure the IP address mapped to MAC address is correct. You can perform a MAC lookup on your router or use a 3rd party website to check vendor of the MAC. Let me know how you go and we can move on to next steps.
