  1. Internet disconnect under heavy load.

    Try downloading a torrent file that has a lot of seeds. Note down the peak download speed. Then leave it for a sustained amount of time. If it does not disconnect abruptly, then your ISP has nothing to do with the problem, in my opinion.

  2. Router considerations when traveling

    Hi, I think you should check if the router supports VPN features first. Then connect all your devices to the router. That's easier in my opinion.

  3. IP Cam connectivity

    Hi, Can you change the IP address of the faulty camera to one that is working? Just to see if it's IP related or else.

  4. Is there way to change the amount of bandwidth that each user gets?

    You can do that if you had some Cisco switches. In fact, Cisco switches allow to control the amount of bandwidth per switch port. It's done with a set of IOS commands.

  5. Relocating a network to another office

    Check if the Internet link is working. You can check with the provider for that. As for the LAN network, do the computers connect directly to the switch or through wall jackets and patch panels? If it's a fresh install then nothing to worry about. Otherwise, sometimes you may encounter a faulty...

  6. Cisco AIR-LAP1142N-A-K9 Autonomous mode

    I suggest you contact your seller and negotiate returning the device as soon as possible. It costs a lot -in term of time and money- to get a Cisco support. Besides, once you manipulate the firmware, you immediately lose the device warranty. Let us know how it goes.

  7. High ping after switching routers

    Could you post more details, such as : - what is the new Internet bandwidth? - what is the type of the link (ADSL, fiber,...)? - Is it persistent or intermittent? - The router configuration? etc.

  8. Multi hub/AP network question

    It's been almost a decade since I've not seen a hub around. Like Boomhover said, get rid of hubs and replace them with switches.

  9. computer connects to network but no internet

    I think there's something messed up with the encryption schemes you are using. Can you apply the same settings as used on Win 7 laptop?

  10. Filter OSPF routes between routers in same area

    Gryz, thanks a lot for the detailed explanation! You understood the situation very well :thumbsup: To answer your questions: Unfortunately not. Yes. Router C advertises it as a directly connected route. I'll get back to the service provider and find a way to convince them :)

  11. Filter OSPF routes between routers in same area

    Sorry for not being clear from the start. It's that I could not attach a local picture to the thread. Here's a simplified topology: https://www.dropbox.com/s/c2u7q17exhtsj5q/2015-07-03%2008_14_40-Dessin1%20-%20Microsoft%20Visio.png?dl=0 Let me add some clarifications: - We're using OSPF as IGP...

  12. Filter OSPF routes between routers in same area

    Hi, We have redundant links to the WAN provider. We are trying to make them work but we get a routing loop between router A, router B and Provider routers, everytime both links are up. Both routers A and B are in the same OSPF area. Each router has a WAN connection to WAN provider The...

  13. E1 PRI interface down

    The issue was on the Telco side. I told the Telco that I was receiving the AIS alarm and just before I was going to restart the CSU/DSU I saw a change on the LEDs. It seemed that they did something meanwhile. Thanks a lot :)

  14. E1 PRI interface down

    Yes we have a separate CSU/DSU. But it's showing everything fine.

  15. E1 PRI interface down

    Hi, We have a E1 PRI interface suddenly down. Here are some show commands: sh int ser0/0/0:15 Serial0/0/0:15 is down, line protocol is down Hardware is DSX1 MTU 1500 bytes, BW 64 Kbit/sec, DLY 20000 usec, reliability 255/255, txload 1/255, rxload 1/255 Encapsulation HDLC, loopback...

  16. Newbie to networking, need help

    No problem. I thought it has not been solved yet :)

  17. Cardio immediately after weight lifting is better than just cardio alone?

    I prefer cardio alone in a 50mn session.

  18. need some advice with weight loss - hypoglycemia

    Eat six meals on a day, instead of three. But have the same quantity. That'll help you get a steady level of glucose through the day.

  19. Are my triceps weak or is it normal for them to give out first?

    Any muscle can be trained, even if it seems weak in the beginning. For example, in my early days, I could not do two clapping pushups on a row.

  20. What is the main source of fat in your diet?

    olive oil and nuts

  21. So I started lifting weights.... Advice

    Patience, and gradual weight increase. Also, cut off junk food to see results faster.

  22. Newbie to networking, need help

    Monitoring: any ICMP/SNMP-based software will do. Configuration: it varies from simple telnet/ssh to Cisco LMS or Prime.

  23. Unable to run Dynamic ARP Inspection Configuration on 2960

    I agree with Imagoon. Your current IOS version does not support DAI (dynamic Arp Inspection)

  24. Cisco board problem

    Did you do any software upgrade? I think the IOS image is not suitable for this kind of hardware.

  25. New Switch to learn on?

    Instead of buying expensive switches, I suggest you start learning about Cisco switching theory first. Cisco has the largest market share in switching (check this slide). Take your time to learn the foundations, because, even if you face "big" switches, the principles are almost the same. Start...

  26. Cisco 2960 switches.

    Switches have evolved from the standard definition of frame switching box to doing advanced layer 3 functions such as routing and NAT. Yes, there still are switches that only do swithing. But I'm seeing more and more layer 3 functions propagate into the LAN.

  27. Network setup question

    I would have preferred cabling rather than wireless.

  28. is spanning tree sufficient?

    For switch path redundancy, add as much cabling as you want and check the spanning tree. Make sure your central switch is the root bridge in STP.

  29. How do you use Wireshark?

    If you want to capture and analyze which traffic sources are accessing your website then Wireshark is great at it. You need to install it between the web server and the network access (the Internet router for example).

  30. Small network issue

    For a solid and time-resisting installation, go with the wall plate, even if it seems less intuitive. Couplers are great on the short term. But, as told by a cabling technician, they reduce the cable bandwidth. And for the wiring, use the same wiring scheme.

  31. Cisco 2851 Routers

    I'd like to point out that HSRP will be used by your internal devices to "see" only one gateway. However, from the ISP point of view, there are two gateways. I'm going to assume Router1 and Router2. On each router, we have G0/1 and Gi0/2 (configured with IP addresses). I'm going to put both...

  32. Need Networking Advice

    Avoid power line adapters. When the electrical fluctuates for some reason, your network will be put on risk. Besides, as told by Inachu, they overheat quickly. I would think about the wireless option instead. And for connecting the computers, you can plug tiny USB wireless adapters such as...

  33. Router died today

    You can go with Linksys. They have been maintained by Cisco from 2003 to 2013. And for small offices, they're great.

  34. Not enough RJ45 ports? What to do?

    Hi, Add a small switch to benefit from additional ports. then plug computers, printers,... on the switch ports. You'll be able to have LAN connetivity and Internet connectivity. That's what I do in small deployments.

  35. Softphone apps compatible with Cisco Call Manager

    I have X-Lite SIP soft phones in mind. I played with them in the past and they are great.

  36. Network Tools to check latency and packet loss

    For Jitter and latency, check this Paessler free tool For packet loss, try Ping Plotter. Check this link.

  37. Cisco Catalyst 6000 vs 6500

    Do you need a technical comparison or a buyer's perspective? Catalyst 6000 switche are no longer sold by Cisco (check this link). I suggest to think about Catalyst 6500 and later, or better, about Cisco Nexus switch family, as mentioned by sonitravel09

  38. Firmware update Issue?

    Can you get to the "At the Utilities --> Firmware Update" page? If yes, do you get the "Firmware update in progress" message? Can you share some screenshots?

  39. Which cheap router for my roommates?

    I have an SMC router at home that shares an Internet connection with the second floor. It is loaded with the necessary features such as MAC filtering, NAT, integrated firewall, port forwarding... I did not want to change it when asked by my ISP.

  40. Looking for cheap POE switch

    Have you tried Dlink switches? I trust this brand for entry-level low-cost switches. check this link: http://us.dlink.com/product-category/business-solutions/switching/unmanaged-switches/fast-ethernet/
