WRT54G wireless router and completely random disconnections

Hey everybody! I recently bought a new desktop computer for my home and after a few weeks I started to notice my internet disconnecting at random times during the day, even when there is a good signal strength (it is only a single wall's distance away). There are three other computers connected to this router, as well as a PS3, and none of them are experiencing any problems oddly enough. To fix the problem I find that disabling and re-enabling my wireless connection works, but it inevitably disconnects soon enough, whether it be in half an hour, 2 hours, or even (but rarely) a full day. As you could imagine, this is incredibly annoying and I cannot seem to find any information to permanently fix this issue. If anybody has some info, please send it this way I would appreciate a lot. Oh and I am running Windows XP Ultimate x64 if that is any help...and the router is version 3. THANKS! - I think I need to be more specific about the problem: when the internet disconnects, access to the Linksys router is “local only,” signal strength is still very good, but for some odd reason the router cannot connect to the internet.

I have a wrt54g wireless router - and need to secure it

I have an older router that has never been secured and need instructions on how to secure it. I printed the pgs off the linksys website but it seems that the link has been broken because I can only get part of it to even show up on line, much less print it. Any ideas? Thanks!

First upgrade/re-flash the firmware on your Linksys router and then try to secure the network.
To upgrade/re-flash the firmware on your Linksys router follow these steps
Go to website linksysbycisco.com/downloads.........insert model no of your router in search tab......select proper version of your router........download the firmware file......save that file on desktop
Firmware Upgrade/Reflash
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...
In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed

WRT54G Wireless Router Problem. Need Help!

I'll start with the basics of my situation and if more details are needed, I will provide to the best of my ability.
I have a comcast cable internet connection. I have 6 computers in my house. Two of them are downstairs (which is where our modem is.) The other four computers are upstairs. All of these computers are Desktop computers with the exception of one laptop.
My laptop (which is Windows XP) can pick up a random wireless signal from the room it is in. I also found out a way to share the internet connection on the computer by going into the properties of my network connection and enabling internet sharing on it. This means if I connect a network cable from my laptop to another computer, I can leech the connection from my laptop and have internet access on the other computer. I also had a switch that I used to connect the other 3 computers upstairs by means of the laptop. The problem was, the laptop was using someone else's wireless connection in the area, and it wasn't strong enough to keep up a constant connection.
I decided, if I can leech someone else's wireless connection, why not have my own. So i recently bought WRT54G Wireless Router and set it up on one of the computers downstairs (because that's where the modem is). It works fine as far as connecting my laptop to the internet from upstairs. My laptop can access the internet through the connection I set up in the LELA program.
Here is the part I am confused about. Everything is plugged in correctly as far as the router is concerned because the laptop can access the internet. But when I connect an ethernet cable directly to one of my other computers (which are Windows Vista, but I didn' t have a problem with it previously when I was leeching someone else's connection), the connection drops on my laptop, and the other computer still can't access the internet. A notice pops up that says its trying to identify the network, but it gives an error that says there is something wrong with the DNS. As soon as I disconnect the ethernet cable connecting my laptop to one of the other computers, the connection is fine again on the laptop. It's only when I connect the computers together that the connection drops.
I just don't understand why it wouldn't work when I created my own network if it worked with another network with no problem. My whole point in getting a wireless router was to have a router within good range to keep up a constant connection on my other computers that aren't in range of the modem downstairs. I just don't know where else to look. I'm not sure if it can be fixed on LELA, manually through my wireless settings, or if it could be a problem with one of my computers' settings. I've tried many different things and I'm not sure what else to do so any help is most definately appreciated. I feel like I've tried everything. I know it's possible because I've one it before, I just need the help because I'm not much of a networking person and I don't know what I should start with to make this work.
Thank you to anyone who can help or even point me in the right direction.

I installed the WRT54G Wireless router on my desktop and have been using the internet on that pc and my laptop (wirelessly) for a few months. Last week I uninstalled Norton Internet Security and installed ESET Smart Security. Now my desktop cannot get to the internet and the advisor says it does not detect a router. But my laptop says it's connected to my network and I am able to use the intenet on it. The router itself has all of the correct connecions and the appropiate lights are lit. Could the ESET Smart Security Software have messed up my router firmware. Please advise.

there seems to be consistant issues with Linksys routers according to all the posts ive been reading for the past month while i try to fix my on and off again internet connection. its becomming very annoying. i have asked my cable company to replace my modem, which they did and that didn't even help. last year i bought a new linksys router thinking it would solve my problem back then. it did for a while, then my lap top wouldn't connect any, so i sent it into have it checked and it came back with no problems. soooooooooo apparently, while i am connected to my neighbors open connection from his BELKIN ROUTER and even though the signal is very weak............amazingly enough!! i am still online while typing this.......funny eh?? WELL........it seems to me......that i guess i wont be buying linksys anything anymore. Especially after spending hours on the help line (INDIA) trying to reset channels and reset the router box itself. i give up.......i have 2 pieces of crap routers for sale cheap......any takers? dont waste your time

Hi guys, I recently got a WRT54G v5 wireless router, and when I try to play the PC multiplayer game Call of Duty 4, it kicks me for having 'No Packet Flow' and "Loss of Key Packets". I didn't get these with my other router so I know that the WRT54G is the problem. It says that you only get these problems if your router drops OOB packets which COD4 uses frequently. How do I stop the router from dropping OOB packets?

Well try reducing the MTU to 1200. And also upgrade the firmware.
To upgrade the firmware :
Connect the computer to the router.
Open the setup page (Intrnet Explorer : 192.168.1.1).
Username :
Password : admin
Go to Administration Tab. Go to firmware upgrade.
Browse and select the bin or img file thats extratcted from the download.
Start to upgrade.
Reset the router and then reconfigure it. Should work.
To check the latest firmware for ur router, click here.
Should help.

Configure WRT54G Wireless Router with PUBLIC IP address and use DHCP for internal computers

Hi,I have an Internet online service with 5 public IP addresses. The router and the AP are connected to a switch. I would like to configure a WRT54G wireless router with one of this IP public Address and use DHCP (with private ip address) for the computers that will connect to the AP. As the AP is connected to the switch it is possible that other wired computers that are connected to the same switch can obtain an IP address from the DHCP ?
Thansk in advance

Thanks for your help. Please correct me if Im wrong. After connecte the equipments the way you suggestI setup a static IP address (The public IP) in the WRT54GI enable DHCP in the WRT54G with a range from 10.10.0.100 to 10.10.0.200 (as an example) The gateway is the Public IP address right ? How do I route the 10.10.0.x addresses to the public IP address. Thansk again

Switched from DSL to CABLE. WRT54G Wireless Router stopped working.

When I switched from DSL to CABLE, my WRT54G Wireless Router stopped working. I am not able to access the router page (192.168.1.1) Also, when I use the set up CD for re-installation, the wizard aborts in the middle saying it can not connect.
I appreciate any help to resolve this problem.
P.S. The router acts like a one-port wired router.

Here is my favorite method for resetting a router to factory defaults, and trying to get it working again.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is dead.
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. In this case, use the Linksys tftp.exe program to try to reload your router with the latest firmware. After reloading the firmware, repeat the above procedure starting with step 1.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.

Hi,
I just bought a linksys WRT54G Wireless Router. My laptop was able to detect it wirelessly untill I changing the "Router Name" in the setup page(http://192.168.1.1)
While saving the settings, the wireless network suddently disconnected. From that point onwards, I was not able to detect the wireless network with any computer at all.
I tried unplugging it, resetting it, and even restory factory settings by holding the reset button for aprox 30 secs.
What is wrong?
Thanks in Advanced

Recheck the wireless setting (SSID, encryption, DHCP, etc) on router management page again. Also make sure your computer's wireless adapter setting matches the one you set on router.

hi
i just bought a wireless router and i cannot get it to work. it is a wrt54g v6. the power light keeps flashing. I tried talking with linksys to get it fixed, but nothing is working. it says to disconnect from the modem and update my firmware, but i cant get the IP address to come up on the address bar. can someone please help me out.
thank you
angela

If you have just bought the router and it has a flashing power light return the router. It is not worth trying to revive a broken router in that case. Return the router and get a properly working one. I would not want to start with a broker router even if you may be able to revive it. You'll never know what caused the problem and whether you will have more issues later.

I have WRT54G Wireless Router on my main computer (VISTA) and I am trying to set up A Linksys Compact Wireless-G USB Adapter (WUSB54G) on my other computer (XP). It is all setup, however I am getting the message "You are connected to the access point, but the Internet cannot be found." To further complicate the issue, when I check the IPCONFIG on the XP computer, I get back some weird IP address that is outside my router's network, even though I'm using DHCP.
I know the router is working - my laptop associates through the wireless network with no problem, and I can access the network printer that is also wired to the router. The problem seems to be in the configuration of the old XP computer with the new WUSB54G adapter.

Try following settings ....
Uninstall the drivers for the Adapter from start >> All programs ....
>> Insert the Setup CD in the cd drive>> Click on Exit when the
Linksys welcome screen appears>>Click on start. Unplug & replug adapter ...>> There should be a "" Found New Hardware Wizard ""
that pops up on your screen>> Click on “Install software
automatically “, and then click on next. Once the installation is
complete>> Right click on the wireless network connection icon in the
system tray besides the clock >>Click on view wireless networks and
then connect to your network name.

New WRT54G wireless router. Who's the genius that can help me?

I just purchased a WRT54G wireless router. The main reason is my son wanted to be able to use his Sony PSP online. I also have two desktop computers that will be wired thru this router. My question's are. If he is using his PSP online and the desktops are wired, can the desktops be "hacked" if they are on/off? If the router is turned off then the wireless is not working? If I access the router and disable the SSID Broadcast then the wireless portion of the network is off? What are the safest security settings to protect my network?
Thanks.

Dead Mans Zone.... I guess.
Using the DMZ is a very simple and risky way to forward ports. The DMZ takes an ip address of a computer on your network, and forwards all ports to that computer. This is really nice if you are having problems forwarding ports for some program. It can be a life saver if your router will not allow you to properly forward ports. It also has a huge downfall. The computer that is in the DMZ is now wide open to internet traffic. Meaning that it will catch virii, and it will be at risk of being hacked. If you put a computer into the DMZ then please install a software firewall to help protect it
Orange/White. The Cisco logo is the Router’s SecureEasySetup button. It lights up and will stay orange when the Router is powered on. The color orange indicates that the Router is not using the SecureEasySetup feature, while the color white indicates that the Router is using the SecureEasySetup feature. When the Router enters SecureEasySetup mode, the Cisco logo will turn white and start flashing. After the Router has generated the SSID and WPA-PSK (also called WPA-Personal) key, the Cisco logo will stop flashing and stay white.

How to set up 6th Generation AirPort Extreme to cable modem as a wireless router and then connect my 3rd Generation Time Capsule to AirPort Extreme as a wireless extender?

What is the best way to set up my 6th Generation AirPort Extreme (A1521) to my cable modem as a wireless router and then connect my 3rd Generation Time Capsule (A1355) to my AirPort Extreme as a wireless extender? I live in a small 1 story house and I currently have the Airport Extreme connected to my cable modem in the living room and the Time Capsule plugged into the wall in my bedroom. I am able to wirelessly connect to the internet using the AirPort Extreme as my router and I can also do wireless back ups to my Time Capsule. My problem is that my connection seems to be really slow! My 1TB Time Capsule back up is only half way complete and it has been 3 days! My computer has been backing up all day and night for almost 72 hours and its still not even 75% complete. I have backed up to this Time Capsule in the past and it never took this long. I am thinking that when I set up my AirPort Extreme and Time Capsule using AirPort Utility I must have set it up incorrectly or something.
How do I set up my Airport Extreme and Time Capsule for the fastest possible internet speed and back up speed?
Thank you,

AirPort Utility 5.6 works with AirPort Extreme 802.11g base stations.
It works with N version airports.
It will also show details of the AC model but cannot be used for the setup.. mostly.
I purposely got the new 6th Gen Airport Extreme so my internet connection would be a lot faster!
Your network will be much faster when you have AC client directly connected to the AE. Older client will go no faster.. but what is worse.. extend wireless is mixing new and old wireless standards.. guess what one wins.. OLD.. So when you extend wireless.. you have no improvement whatsoever. This whole post is about extending wireless.. so you cannot extend to older equipment and do any better.. maybe slightly better signal although from your comments that isn't happening either.
I would rather not have to use an ethernet at all with the TC and I don't know EOP adapters are!
If you do not use ethernet then you are going to be forced to accept slow speed.
EOP (ethernet over power). Also called homeplug in the US.
http://en.wikipedia.org/wiki/HomePlug
Provides a method of networking over power cabling that already exists in your house.
So what your saying is for the fastest internet speed and back up speed possible I should keep my Airport Extreme plugged into my Modem and keep my TC set up as a wireless extender? Then when I want to do back ups I should plug an ethernet cable from my TC to my MacBook Pro?
To spell this out.
A wireless link to an extended device will go very slowly.. if it is not direct.
So lets say you have a laptop sitting in the lounge.. Your connection goes.. Laptop- - - - - AE- - - - -TC.
That means two wireless links.. wireless has this nasty half duplex and single channel nature.. it can send or receive (Tx or Rx) but not at the same time.
Ethernet by contrast does both at once. It is full duplex.
Wireless can talk to one client at a time.. so if there are multiple items using wireless lets say 4 devices.. then your computer gets a 25% time slice. Since wireless cannot handle multiple simultaneous connections.
Ethernet by contrast can connect multiple computers to multiple destinations at the same time.. all transmitting and receiving at full speed.
When you put all this together.. there are a couple of rules for fast connection.
1. Use ethernet at all times. Where you cannot use ethernet use anything but wireless.. eg EOP (homeplug) at least to try and get rid of wireless.
2. Where you must use wireless use it sparingly and make sure it is never more than one hop.. ie never have an extend wireless (repeater is more usual term). Repeater will cause instant slowdown of 50% and maybe up to 75% just because it is so inefficient.
3. Fastest wireless is 5ghz but it has very short range.. you need to be up close and personal to get it working.
Apple routers however unless you do manual setup I suggest are set to connect to best signal strength not best speed. It will therefore use 2.4ghz at 25% less speed than 5ghz because it is 1db better signal.. this madness means you need to setup manually for the best setup.

Wireless router and base station help

Hello fellas -- I'll really, really appreciate any help I can get with this, so thanks in advance for any advice given. Here we go...
I purchased a MacBook (2.16 GHz Intel Core 2 Duo, 160GB hard drive, 2GB RAM) about two months ago. It runs Mac OS X Tiger (10.4.9). Previously, I had a Sony Vaio desktop in my downstairs bedroom, and an HP Pavilion desktop in my mom's office upstairs. I have Comcast "high-speed" cable internet service. Downstairs (where the Vaio was) I have a surfboard cable modem with three cords coming out of the back: 1.) a power cord (obviously); 2.) a cable cord that runs into the wall for internet service; and 3.) an ethernet-looking network cable. This ethernet/network cable would have normally run right out the back of the surfboard cable modem and into the network port on the back of my Sony Vaio, but in order to provide internet service for my mom's HP upstairs, the network cable went from the back of the surboard modem and into a D-Link wireless router that we bought. Another network cable then went from the D-Link wireless router into the network port on the back of my Vaio. This provided both my Vaio and my mom's HP with good, steady cable internet access.
When I bought this new MacBook, it came with an AirPort Extreme card (no base station yet) that allowed me pick up on the wireless signal from the D-Link wireless router and this provided me with internet service. To connect to the internet, I would connect to the wireless network that my computer called "default." By this point, I had shut down and unplugged my Vaio, so it's out of the picture now -- the MacBook has replaced it. However, I left the surfboard cable moden and the D-Link wireless router plugged in, and this way I was able to connect to the default network wirelessly with my MacBook, and my mom was still provided with wireless service from the D-Link router on her HP upstairs. This worked great for awhile, until eventually this default network started getting rediculously slow and started disconnecting itself every 30 to 45 seconds -- literally. For this reason, I went out and bought an AirPort Extreme Base Station at my local Apple Store.
First, to make sure it worked, I unplugged the network cable (the one coming from the back of the surfboard cable modem) from the back of the D-Link wireless router and I plugged it directly into the base station I just bought. In other words, I took the D-Link router out of the picture and plugged the base station directly into my surfboard cable modem. This worked great, and it's how I'm connected to the internet as we speak -- it's providing me with steady, fast service. Instead of connecting to the default wireless network that was slowing me down before, I now connect to the base station's network, called "Apple Network 2b1d46." There's only one problem, though -- it involved taking the D-Link wireless router out of the picture, so now my mom can't get on the internet with her HP. The solution seemed very simple -- instead of plugging the surfboard cable modem directly into the base station, I would plug the surfboard modem into the D-Link wireless router, and then plug that into the base station. I saw no reason why this wouldn't work, and I still don't, but for whatever reason, it didn't.
This is where I need help. When I try to plug it in through the router like that, I simply can't get on the internet. Everything else works perfectly -- the surfboard cable modem's lights are properly lit, as are the D-Link router's lights. The Apple base station's status light is a solid green like it's supposed to be, and strangest of all -- when I open Internet Connect to check my AirPort status, everything is fine there as well. It says "Connected to Apple Network 2b1d46," which is the new base station network that I should be connected to, and under that it says "Connected to the internet via Ethernet," yet when I try to open Safari, it says "You are not connected to the internet," which is in direct contradiction to what Internet Connect is simultaneously telling me (that I am connected to the internet).
I've tried alot of things to trouble-shoot this. I've tried FireFox and Opera, and they can't bring up any web pages either, so I know the problem isn't just with Safari -- it's that my computer just can't connect to the internet or bring up web pages, even though Internet Connect and everything else says that it's connected. I've also run the Network Diagnostics an uncountable amount of times, and all it can tell me, in all its wisdom, is that my internet connection appears to be working fine and that I must have spelled "www.apple.com" (my home page) incorrectly (it says the same thing about any other web page I try to open). I've ran the network assistant to create a new location, and it also gets the the end of the wizard and tells me that it can't connect to the internet. Finally, I've also ran the AirPort Utility multiple times and set up the base station in every possible way, but still nothing works.
On that note, I do have one question. When you run the AirPort Utility and choose "Assist Me", at one point during the wizard it asks, "How do you connect to the internet?" Right now, remember, I have the D-Link wireless router taken out of the picture (the base station is plugged directly into the surfboard cable modem). For the answer to this part of the wizard, I chose the option that says, "I use a DSL or cable modem with a static IP address or DHCP." Obviously, given that I'm on the internet as we speak, this is working fine. However, if I bring the D-Link wireless router back into the picture and plug the base station into it (the router), and then plug the router into the surfboard modem, should I still have the same option checked (the one thats says I use a DSL or cable modem with a static IP address or DHCP), or by connecting through the router, should I change my answer to one of the other two options. The second option says, "I use a DSL or cable modem using PPP over Ethernet (PPPoE)." The third option says, "I connect to my local area network (LAN)." I've tried all three numerous times, and none of them work -- I still have the same problem getting on the internet once I connect through the D-Link router, but I thought I could at least find out which one is the right option so I could stop having to keep trying all three of them. Can anyone tell me which of those three options I should pick when connecting through the D-Link wireless router (cable modem with static IP address or DHCP, cable modem with PPPoE, or local area network).
Sorry, I know that was a long one, but if anyone can answer the previous question for me and/or give me some general advice regarding my problem with getting the internet to work once I hook up the base station through the router instead of directly into the cable modem, I would appreciate it more than you can imagine.
Thank you very much for your time and help.
-- Andrew

I am doing something similar. I have the WAN port on my Linksys 4-port wired router connected to my DSL modem. My G5 and G4 computers are connected directly to the Linksys LAN ports. My older Airport Extreme (flying saucer) is connected to another LAN port on the Linksys. I had to setup the Airrport as a bridge in this configuration. I did this by using the Ethernet LAN port on the Airport instead of the WAN port. In the Airport Setup Utility I said to connect using Ethernet. This seems to work for me.
I also use manual IP addresses for everything but you will probably want to use DHCP.

TS1453 Apple TV doesn't show up in my iTunes. I've done all the troubleshooting steps, updated all software, restarted Apple TV, wireless router and computer. Devices doesn't show up at all in my sidebar.Apple TV doesn't show up in preferences

Help. My Apple TV won't sync with my computer. I've done all the troubleshooting tips, but Apple TV doesn't show up in my Preferences under devices.
2. Reconnect Apple TV to iTunes.
Choose iTunes > Preferences (Mac) or Edit > Preferences (Windows), click Apple TV, and make sure "Look for Apple TVs" is selected.
I see no option to select "look for Apple TV's" in Preferences, and there is no device list at all in my sidebar.
3. If Firewall is on in Mac OS X (in the Sharing pane of System Preferences), make sure iTunes Music Sharing is selected.
There is no option to select iTunes Music Sharing in my System Preferences - see screenshot
I've updated all software, restarted Apple TV, my wireless router, and my computer. Both my computer and the Apple TV are connected to the same wireless network and both are operating properly. They just wont connect to each other.
Does anyone have any suggestions?

FIRSTLY: bookmark following for further reference (it describes basic setup, both to link for syncing and to stream - from any computer.)
Apple TV (1st generation): Differences between syncing and streaming" )
Now as to your problem: If you check under "Computers" in the "Settings" menu you will most likely see the name of your iTunes library Greyed out. IF that's the case, you'll basically need to re-setup your ATV., you can do so as follows (instructions are intentionally over described, but basically your disconnecting then reconnecting your ATV1. Downside (which seems to come with all methods is that you'll have to resync all your media)
**A (not ideal but effective solution)
If ATV 1 had been working but suddenly 'disappeared" from iTunes sidebar
The following solution will almost surely work to regain your ability to Sync:
QUIT iTunes
Select "Computers" from "Settings" Menu.
Select your "greyed out" iTunes library.
This will bring up a window named "Disconnect from iTunes"
You're now given the choice to Cancel, or disconnect. WITH THE WARNING that if you disconnect any content synced with iTunes, will be erased. (in fact it will be removed from your ATV but not your computer)
Assuming ALL of your media IS on your computer, Go ahead and disconnect.
Follow instructions in the Apple doc above about setting up your ATV as a paired computer.
After you ATV gen1 reappears in the sidebar. Reset all your desired syncing preferences,
Begin syncing.
All will be fine again, (at least till the next time this occurs.) I've had to do this twice this year.
ALTERNATELY:
SHARING (a QUICKER, less destructive TEMPORARY solution (if you just want to play your media now)
You CAN set your computer to Share by following instructions in the same doc under the heading:
"How to connect to a shared computer"
HOWEVER, this will not allow you to sync info.
I've read alternate solutions on this board, one involved changing the name of your iTunes Library etc... you may wish to try this first (if it applies) https://discussions.apple.com/message/17943841?ac_cid=142432#17943841
What I'd like to know: What causes this problem... I'm suspecting iTunes updates, or any iTunes database issues or crashes. Or maybe too many visitors connecting to your other Apple devices (ATV 2 for example) or heck the weather in Guatemala...

I have a HP Officejet Pro 8500 wireless printer conneted via WiFi to my LYNKSYS WRT54GS wireless router. I do not have a USB cable or ethernet cable plugged to the printer. I am able to use the 'scan to email button' and the 'scan to network folder' button on the front of the printer and I can pint from the PC to the printer with no problems.
I installed the HP printer software from the CD, choosing network/wireless connection, without having to install any USB cables from the PC to the printer in the process. many posts in the forum mention having to connect USB cables in the wireless installation process.
Can I install the software in the same fashion on the other two laptops? Or, do I need to do something differently?

The USB cable is used on those printers which do not have display or front panel wireless setup is not possible. We configure the wireless settings during install and save those settings in printer's memory by transferring through USB cable. Therefore the USB is plugged in during wireless installation temporarily. In your case I don't think plugging in USB cable is necessary as the printer is already on network and had IP address. Connect the laptops on wireless network and proceed with regular install, the printer should be detected automatically.
