First off, you don't connect to your router through a COM port. Secondly, you DO connect to your router generally through a web-based utility. Why don't you try reading your documentation thoroughly. It probably tells you to go to your browser and type in http://192.168.1.1 to connect to the firmware. WTF would you be using HyperTerminal for anyways? Want to emulate a VT100 terminal? Trying to bring back the good ole days of time-sharing on the mainframe?

Firmware = software that lives in hardware (yes, that does sound wierd). \n\nIf it is programmed into flash memory or read-only memory it is called firmware. In your case, the router uses flash memory to store it's program.\n\nGo to the router maker's website and see what it takes to do the actual upgrade (usually not very complicated).

You have probably have done this have you check to see if you have the latest bios. Also see if HP has anything on there website.  You are move advance then most of the people here the only thing I can do to help you out is bounce ideas off of you.  I don't have my network doing a network boot or anything like that.  I have some frineds that use centrix but they have a OS on the systems.  Good luck if you need to bounce idea off of someone imz me.

Cause:\n\n    This issue could be caused by any of the below possibilities.\n\n                1. Boot options are not set properly in CMOS\n       Ur issue:2. Non bootable CD or CD-R in computer\n                3. All boot devices set are not bootable\n\nSolution:\n\nNON BOOTABLE CD OR CD-R IN COMPUTER\n\n    Verify that no CD or CD-R is in the computer possibly causing the computer to attempt to boot from that disc. \n\nWhen the computer restarts, u get an option boot from cd or not.\nUse arrow keys and choose the other option..it will work!\n\n(Am assuming tht u used a cd to install the software)

With the information provided i.e. no model #, unable to determine step-by-step. You will have to refer to your router documentation. Some things to consider (and write down as you go):\n1) rename the default ssid to something non-obvious\n2) disable broadcast\n3) enable encryption using WEP or WPA (preferred)\n4) enable MAC address filtering\n\nTo obtain the MAC (physical) address of your wireless network interface card (NIC) and assuming Windows XP\n  - click on the wireless icon in your system tray\n  - click on the support tab\n  - click on the details button\n  - write down the physical address\n\nIf that doesn't work:\n  - Start / Run / cmd <enter>\n  - ipconfig <enter>\n  - find the section in the output for wireless card\n  - copy the 12-digit MAC address (excluding dashes) on the "Physical Address" line\n  - type EXIT <enter> to exit the dos prompt window\n\nIn your router configuration screen, find the location to enter the MAC address(es) of connected machines. Enter the MAC address you wrote down in whatever format it indicates. [Note: some routers will have an option to select from currently connected machines. Compare the MAC addresses it displays with the ones you wrote down before accepting them.]\n\nTypical access to your router configuration is by using a web browser to open the IP address of the router's internal address. Linksys routers for example are usually http://192.168.1.1/ and you will be prompted for the factory user name and password. Refer to the user / configuration manual for this information. YOU WILL WANT TO CHANGE THE DEFAULT USER NAME AND PASSWORD, AND WRITE THEM DOWN IF YOU CANNOT REMEMBER THEM. Otherwise you will have to do a factory reset at some point and start over.\n\nYou will also have to make configuration changes on your PC wireless configuration to enter the new SSID name and other key-related information depending on whether you chose WEP or WPA. Again the instruction manual should step you through it, there is usually a section that specifically addresses security.\n\nIf you follow those recommendations and those posted here by me and others, your wireless network will be 99% more secure than most other peoples and you will be fine.

try to go into the cmos and boot from the disk, you need to try to get virus/worm protection because it sounds like the w32 ircbot worm...i had the same problem and had to completely reinstall everything...good luck, i hope you can get it fixed\n\nhere is a mcafee link about the virus...\n\nhttp://us.mcafee.com/virusInfo/default.asp?id=description&virus_k=135491

what type of modem do you have? are you using a router? make sure you sequence power cycle modem first then router and pc if you do have. if still not then isolate router and plug modem directly to pc- , and you  have speed stream 5100b or 4100 ( 5 LEDS) then open a browser (IE) type 192.168.0.1 - \nif you can't pull it up, disable any firewall or anti virus or check LAN making sure it's enabled\nit should open sbc effiecient network- \nif you have internet light on your modem - then it means your modem might be saing default username and password- if no internet light- do the following for wither of the 2 situation: \nclick advance button on the left- then connection configuration - usually it will be asking for the modem access code- then type the correct username and password- click restart and ideally it should connect you to the internet- \n\nif still not- try disabling any firewall or anti virus\n\nif still not- there could be an outage and you may have to call \n1-877-722 3755 - it's toll free\nbecause you might be having a 2 wire modem/ router and it's another story- lol

Did you install service pack 3? That happened to me when I did.\n\nThis is what worked. First, unistall service pack 3. THen, unplug your MODEM. Leav it unplugged for 20 seconds and then unplug the router. Leave it unplugged for 20 seconds.\n\nPlug the MODEM back in and wait for the lights to go back to normal then plug the router back in. \n\nRestart your computer, and then go to your LAN settings. Click on detect network. At first it will probably say no network found, but do it again. It should come back on.

check your IP  configuration it sounds like you need to make some adjustments.  The computers were never configured on a private network were they? How about the router have you configured that? See if the PC is getting assinged and IP address by the router. Go to start menu, select run, type cmd, then press ok, then in the dos window that opens type ipconfig and press enter.  Does it come back with your IP address, etc.? What does the default gateway say?

Do this: Start-Control Panel-if not in classic view, change to classic view, then double click on System. In System, click on the Hardware Tab, then click on the Device Manager button. A window will pop up, this is your Device Manager. Now, you should have a list of Hardware which is installed on your System. Browse down the list and look for Network Adapters. Click on the "+" sign to open and read the entries there. If there is no listing for Network Adapters, which there should be as you should have an Ethernet Adapter as the very least, then you do not have any adapters installed. That would be a rare case indeed. Now, the Ethernet Adapter will have either a 10/100 or 10/1000 desription, depending on how new the computer is and if you paid for an upgrade in the Ethernet Adapter. Look for a listing which is not designated as 10/100 or 1000, double click to open Properties and read the desription. You may also have your FireWire listed there, even though it is not really a Network Adaper. FireWire will also be listed in your Network Connections too, why I am not sure, but that is how Windows handles FireWire right now. So, FireWire is 1934 IEE, which is not a Network Adapter. \n\nThe above is the best way to see what you have installed on your sytem. This will also tell you if it is working correctly. When you open Properties, down in the first Tab is a small area which will tell you either "This device is working properly", or "This device is not working". \n\nOnce you know what you have installed you can move forward with using it for Networking. \n\nGood luck and have a great day!

First of all: Tattie Herbert.\n\nIf you mess up nothing will break. Do your homework and get out of here!\n\n1) There is an 3pin switch on the motherboard. It says "clr cmos".\nPut it from 2-3 to 1-2 switch on the computer, switch it off, put it back to 2-3.\nThe cmos is now reset.\n\n2) I turned off Soundcard, Modem and Videocard (Use better ones) and set the boot option to c: only set memory to turbo and disabled floppy and enabled s.m.a.r.t. capability and cable detect on ATA100.

have you tried :-\n\nhttp://www.free-tests.com/cisco-ccna-test.cgi\n\nAs for advice\n=========\nLearn to subnet, subnet & subnet. i.e.  if you want to subnet in your head try this trick 'interesting part' of the mask (the number that isn't 0 or 255) subtract if from 256! This will find you the 'magic number'. multiples of the magic number are the network addresses. Next multiple minus 1 is the broadcast, b/c -1 = last host on that network etc. That's a quite useful tip! [255.255.255.252, magic no = 252. 255 - 252 = 4 the networks are 0, 4, 8, 12 etc. if 4 is the n/w address 8-1 (or 7) is the b/c address etc etc etc.\n\nhere are others:-\n1) be able to explain CSMA/CD\n\n2) know the difference between a collision and broadcast domain\n\n3) know which addresses are physical and which are logical (logical = layer 3)\n\n4) Know some Layer 4 protocol examples\n\n5) understand what devices operate at what layers (a modem is a layer 1 device!!)\n\n6) RIP - practice configuring it (on paper will do) & debugging it, you may well get a question where it isn't working to debug. It's particularly helpful to remember the requirements to physically get RIP going out an interface.\n\n7) also vlan database commands - you'll probably need to config a vlan somewhere\n\n8) also revise ACL's - you want to be able to capture all of a certain kind of traffic .. can you?\n\n9) Do you know what your Administrative distances are for?\n\nPlease do not throw sausage pizza away\n\nBest advice = don't panic & if you are struggling for more than a minute on a particular question (unless the others were really easy so far) ditch that question so you don't run out of time!
