Rv042 change wep security to wpa2

i have a linksys rv042 router and it currently has wep security enabled. i need to change it to wpa2 for pci compliance. i cannot find anything about this in the user guide, tech support says the warranty is out, and the web management console has nothing about wi fi at all. there is no other wi fi on the network, i have two dlink switches and a cable modem. please help me, it's been two days on an hour long job.

the only things connected to the network are a small cable modem, the rv042, a nettrend switch, two telephony modems(no rj45), and a dlink switch in another room supplying the printer and a laptop. since the switches are dumb, and the cable modem is just a modem and not a router, the rv042 is the only thing that it could be. we traced all wires physically and there is nothing else hooked to the network in the building. the reason i know it's not another wi-fi network (there are several on the list) is that the server machine was talking to the other machines while they were hardwired. i am getting the same info as you, that the rv042 is not wi-fi capable, but there is no other choice. can an internal antenna be placed inside? the guy that set up the network said it had an internal antenna, but the technician working with him cannot be reached and he is not technically literate. i have solved the problem by purchasing a 2950 switch and when it gets here, i will set up a seperate vlan for the pos machines, but it still bugs me that i couldn't figure out the issue and they need to get the wep turned off.

Won't connect to WEP secure router

I have a d-link xtreme n router. I just changed the password from WPA2 to WEP. Everything is fine with every other computer except for my sister's MacBook Pro. For some reason, it refuses to connect to the router if it is WEP protected. It worked fine with WPA2 and it's working without security. Can anyone help me with this?
Also the reason I changed the security was because certain things in my house are only WEP compatible. I would not like to change it back to WPA2.

I had the same problem with my MBP
Here's how I fixed it:
- I SKIPPED the network setup assistant.
- Instead, I used native system preferences, then clicked network.
- I clicked the + sign to add a network
- Typed in SSID of my home wireless network
- (IMPORTANT) in the field below, I was able to specify 128 bit WEP hex *** HOW COME I DIDN'T SEE THIS OPTION WHEN I USED THE NETWORK SETUP ASSISTANT? *
- applied the changes, and I'm on.
Sounds like the network setup assistant has some limitations?

Intel 5300/5350 Intermittent Wifi Solution - Don't use WEP security!

I recently purchased a Lenovo T400 with the Intel 5350 wireless card (same as the 5300 but with WiMax), and, like a lot of other people on this forum, I could not get the wifi to consistently work. I spent several frustrating days searching these forums and trying pretty much every solution offered (XP 32 bit, Vista 32 bit, Vista 64 bit, w/ & w/out Access Connections, w/ & w/out Intel software, Lenovo drivers vs. Intel drivers, etc.). However, in the end, the solution was totally unrelated.
What I found was that when I was using WEP security on my Linksys WRT54G router (v5 w/ the latest firmware) I could not get wifi to work consistently. In most cases it was hard to get it to work at all. In other cases it might work after a reboot for a few minutes, then stop working again. However, as soon as I either turned off security or changed it to WPA2-Personal, wifi worked like a charm.
I was originally thinking about returning the laptop, since no wifi makes it pretty much unusable. But, with this finding I think I will keep it. Since it is obviously a driver issue, I'm going to assume there will be a driver update in the near future to fix the problem.
Hope this helps some of you who are having the same problems!

That is a fascinating solution to the intermittent mess the Intel cards can go into. Never would have thought secrurity and encryption would affect the performance.
For what it's worth, go into the properties of the wireless card in Device Manager. Go to the Advanced Tab. Set "Roaming Aggressiveness" slider to the lowest, "Power Managment" to lowest, and "Transmit Power" to highest. These were solutiosn that I've run across and fixed the problem for me (I have the regular 5300, hope you will get to use and enjoy WiMax).

Problems with WEP Security?

If you are having difficulty making a wireless connection to your home network, check whether you are using the WEP security method with Shared Key authentication. These HP wireless printers do not support this security method, which is the least secure of the methods available. If you are unable to connect for this reason, the printer will indicate that the problem may be caused by MAC address filtering, which is misleading. To correct this problem, configure your wireless router to use one of the following supported security methods, all of which are superior to WEP/Shared:
·  WEP key encryption using either Auto or Open authentication
·  WPA
·  WPA2
Changing your router configuration from WEP/Shared to either WEP/Auto or WEP/Open while using the same WEP key, will allow most other wireless devices on your network to connect without your having to change their configurations. However, you might take this opportunity to update your security to WPA or WPA2 which are both far more secure than WEP. If you change your security type from WEP to WPA or WPA2, you will need to reconfigure all other wireless devices that connect to your network with the new settings.
After changing your router's security method, before attempting to connect your HP printer wirelessly, we recommend that you either restore network defaults from the printer’s control panel or turn the printer power off and then on again.

change the router to use WPA. worked for me

Can't select WEP security setting.

Hi, I just set up a DPC3825 router, and I wanted to use WEP security settings so my DS Lite can connect to the internet, but it appear the only options in the Wireless > Wireless Security dropdown list are :
WPA-Personal
WPA2-Personal
WPA or WPA2-Personal
Disable.
Anyone know what's going on?

Instructions for setting WRT54GS security to WPA2? Can't find them anywhere.

Hi,
I'm an amateur at this, so please excuse this load of ignorant questions.
I have 2 PC clients, both Dell Dimensions 3.2GHz 1GB RAM, Wireless-G adapters. OS is Windows XP SP2
The router is a Linksys WRT54GS. I'm using the wireless ports only, at least when I'm not modifying the security settings. Then I use a temporary cable to connect one of the PC's to the router.
I also have a TiVo DVR series 3 with a wireless adapter.
The router came with a copy of Linksys Advisor. When I ran this software I was able to set the security level to WPA-Personal. However I could find no option to set the level to WPA2.
I know the TiVo supports WPA2 because I saw the option when I was configuring it for WPA-personal.
My question(s):
Why doesn't EasyLink Advisor have an option to set the security level to WPA2? Is it just deficient, or does it check to see if the client PCs support WPA2 and disable the option if they don't?
How would I go about checking if my PCs support WPA2?
Finally, if I have to set the security to WPA2 manually, what is the procedure for doing this?
It's pretty easy to see how this can be done on the router's little web server pages; but as soon as I set the security to WPA2 there, I'm going to lose wireless connections to the PCs and I won't be able to access the router.
I know I can get there via a cable connection, but then what do I do? How do I set up my clients for WPA2?
What's a real pain about all this is that the EasyLink Advisor gives hints on how to optimize performance on secured wireless systems. It advises going to WPA2! But its Wizard doesn't give the option to do that. Its offline help file is minimal - it just says "use the wizard" and that's it.
The online help describes how to manually configure WPA but not WPA2. And the instructions for WPA are incomplete. They explain how to set up the router, but then do not explain how to use the enccryption keys when reconnecting client PCs. They just say to select the SSID in the wireless icon's connect menu, then click on connect. Where does the key go?
Thanks for your time in reading this,
Big Al Mintaka

First of all, Windows XP SP2 can do WPA2, however it requires a patch.   Go to Microsoft Knowledge base, article ID=917021 and it will direct you to the patch.
Sadly, the patch is not part of the automatic Windows XP updates, so lots of people are missing the patch.
Additionally, be sure to give your network a unique SSID. Do not use "linksys". If you are using "linksys" you may be trying to connect to your neighbor's router. Also set "SSID Broadcast" to "enabled". This will help your computer find and lock on to your router's signal.
As to why EasyLink Advisor works the way it does - I just don't know.
To setup WPA2, you will first need to patch Windows XP, then, using a computer that is wired to the router, go into the router and change the encryption to "WPA2 - personal" with "AES". Reboot modem and router. You are correct that you will now loose your wireless connections until you update the settings in your wireless devices.
Next go into your computers and likewise change the encryption to "WPA2 - personal"  (= WPA2 = PSK2 ).   (Note: You do not necesarily need to specify "AES" in your computers (or Tivo), but if you are given a choice between TKIP and AES, choose AES.)
To find these settings for your computers, go to the wireless software in your computer, and go to "Preferred Networks"  (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. Delete your current network (this will clear any old settings). Reboot computer. Return to "Preferred Networks" and enter your network info (SSID, encryption, and key). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings". Reboot computer.
You will need to check the Tivo manual for how to change the Tivo to WPA2.

Port forwarding security cameras WPA2 blocked?

I just bought an Airport Extreme router and set up port forwarding for home security cameras.
When I have no security - I can access the cameras remotely (iPhone) and locally with no problems on my iPhone. However, when I add on WPA2 security everything gets blocked. Is there a firewall or feature inside the AEBS that needs to be modified? Help!

The fact that you can access the cameras remotely verifies that the port settings are correct on your AEBS.
Wireless security does not use ports as it is a local network feature so no additional base station settings should be required.
The issue appears to be with your iPhone Wi-Fi connection when wireless security is enabled. WPA2 is supported with all iPhone models.
I would recommend at this point to change the security password to see if this resolves the problem. Temporarily try the following as the base station's Wireless Security password: 0123456789abcdef0123456789
Note that there are exactly 26 characters. If this works, go ahead and change the password. I would recommend one that contains a combination of 26 letters, numbers, & punctuation marks without using any spaces.

Mimo access points with Static WEP security do not allow connection speeds above 54mbps

I am getting this message:
Access Connections - Mimo access points with Static WEP security do not allow connection speeds above 54mbps
If I switch from WEP to WAP i do not get the message but I still only get 54mbps speed. I have a Linksys Wireless-N Broadband Router. Is there a setting that I am missing???

Yes you need to use WPA-AES or WPA2-AES, or no encryption, to go faster than 54Mbps. This is part of the 802.11n spec.
That's not so bad, because if you have the right 802.11n card and use the right settings you can go up to 300Mbps!
What bites is that the 802.11n card which comes with X-Series ThinkPads is the Intel 4965AGN. It does not support the broader 802.11n 40MHz channel width option, limiting the top speed to 130Mbps .
The new ThinkPads based on the Montevina/Centrino 2 platform will most likely use the Intel WiFi Link 5100/5300 802.11n/WiMax cards, which I hope will fix this, coz I'm going to buy one!
I don't work for Lenovo. I'm a crazy volunteer!

Windows laptops can't connect to Macbook Pro shared internet when WEP security is on

As the title states, my Windows laptops can't connect to Macbook Pro shared internet when WEP security is on. My iPhone has no problem asking for the password when I try to access the shared internet my MacBook Pro on Mountain Lion is sending, but my Samsung Slate on Windows 8 sees the network and only succeeds in connecting when no password is required. When security is on, it just tries for a moment and says it can't connect to the network without ever prompting me for the password. The same thing occurs on my Asus Netbook running Windows XP. Since all the reviews about OS X's internet sharing mentions "any wifi device" can access it, I haven't assumed it's only compatible with Apple products. I want my MacBook Pro to save me from needing an external router.

I would post a new question, outline the specific problem you are having and skip all the extra. Outline any steps you have taken already to try and solve the problem. Post the question in the forum most likely to have followers who can answer your question. Give your topic a good title such as: My MacBook Pro cannot connect to my WEP-enabled PC.
Provide any hardware information that may be relevant such as the make and model of your router and method of connection - wired or wireless.
I'm no authority, but have you tried using WPA2/Personal on your PCs? This method is most compatible with Macs.
If the WEP password is a hexadecimal password then on the Mac you need to preceed the number with a $ sign or the hex digits, 0x.

AX WEP Security Problem

I've just pulled my AX out of the closet for the first time in a couple of years. I want to use it as a client on my home wireless network to stream Internet radio over my home stereo system. I've gotten it to work--but only without security on my wireless network. Without security, everything went as scripted. But before that I tried it three times with WEP security enabled and failed each time. I won't bore you with the details, since obviously (since I got it to work without security) I went through the correct procedures. I'll just provide a couple of details here.
* During the setup procedure, everything seemed to be going perfectly until the end.
* During the procedure, I specified WEP security and gave the utility access to my keychain, where it accessed my WEP password. I 'showed' the password to make sure it was correct.
* Setup was successful (according to the admin utility) but after restarting a connection between the AX and the existing network could not be established. The light flashed amber and the device disappeared, inaccessible either directly or through the existing network.
Don't know which WEP this is, but the password is 5-digit hex.
Thanks for your help.

I want to use it as a client on my home wireless network to stream Internet radio over my home stereo system.
What is the make/model of your current home wireless network's router?
But before that I tried it three times with WEP security enabled and failed each time.
Any reason that you can't use WPA or WPA2, instead of WEP. WEP is no longer considered secure and it doesn't play "nice" when working with different vendor's equipment.
Don't know which WEP this is, but the password is 5-digit hex.
One of the problems with WEP is that the actual standard relies on a 10 character HEX key for 40bit WEP and a 26 character HEX key for 128bit WEP.
In order to make things easier, vendors use certain algorithms to convert simple alphanumeric passwords (or passphrases) into HEX keys, thus enabling the use of simple easy to remember WEP password rather than lengthy HEX keys. The problem is that different vendors use different algorithms to generate the HEX key and therefore a ASCII password on an AX will be hashed differently on a non-Apple client and vice versa.

Are wi-fi issues MBA or Lion? Anyone changed WEP to WPA?

I have 3 Macbooks in the house. The only one having connectivity issues is my new Air - connection goes in and out. At home, I have WEP security. At work, I never have connectivity issues - it's WPA security. I'm wondering if anyone has made this switch and if it helped. There is much debate whether the problem is Air or Lion related. But seems that more AIr people are complaining. I'm also wondering if my best solution is an Airport. THoughts?

I changed my 2wire modem to WPA and the difference was immediately noticeable. I did this at the suggestion of an AppleCare tech guy who mentioned something along the lines of 'Lion is designed to work with a WPA protocol'. I can't quite remember but it was something to that effect. Anyway the point is, it worked. And while I still do get disconnected on occasion it's nowhere near as often as it was with WEP.

C4580 Wireless Networking Issue - WEP Security Key not accepted.

I keep getting this error whe doing network setup on my new Photosmart C4580.
"Your wireless rounter requires a WEP secuirty key. The security key configured on your printer does not match exactly. Reconfigure your wireless network WEP security key for your printer."
I have downloaded an updated installer. I have tried to access the printer via the IP address to make the change. It is never updated. When I run the Wireless Network Test Report it also shows it fails. I am entering in the first WEP security key (Index 1). I know the key is being entered correctly. I have even copied and pasted it. Nothing works.
Help Please!

Jim:
Thanks for your comments. I think you may be right. I have more information now. I installed a later version of the C4500 package (to fix another problem where the PC Firewall and internet access was disabled for 3 mins at startup), and the network setup/diagnostics are different in the newer package. After installing this the first time, everything worked - I mean everything, even scan from printer. During the Network Setup the wizard found only one network (mine). However, the Wireless Network Report said it had detected two.
However, the next time I switched the printer on, it never connected. Network diagnostics then told me that the PC and the printer were on different networks, 192.168.0.0 and 169.254.0.0 and that this usually results from two close networks with the default router manufactures SSID. This is not the case here - I am in any case in a very isolated country farm! It also (predictably) said the WEP was wrong. At one point in the diagnostic I can see it's trying 169.254.196.213. There's nothing on my network other than 192.168.0.* Attempts to reconfigure the network again show that there is only one network detected on-air, and no duplicate SSIDs, but the same result in the diagnostic - crossed-networks. Even re-installing the software won't fix it now. Whereas before I could at least print/scan from the PC and only the printer 'thought' the network was dead, now the network really IS dead and I am left with a USB-only setup.
I think you may be right that the printer somehow 'remembers' a phantom/ghost network. What I need is some way to hard-reset the printer. I saw in other postings that you know something about this, at least on other printers. Alternatively, I need a way to set the printer network parameters, including hard-coded IP address, over the USB but WITHOUT the router radio on, then switch it on and let the HP network setup wizard find it over the radio. Any ideas on that one please?

Unable to change B210a to use WPA2 + AES

I am using a TP-Link router with Mixed NG Mode, Security is WPA2 with AES (not Mixed).
When i try setting up the B210a to connect to the wireless with Setup Assistant, it only shows the Encrption type as WPA PSK for the Wireless network, but it is actually WPA2 personal. So if i go ahead with the settings that are showni see it connects without any issues. However i see it only connects with g speeds. I understand this has Wireless n capablities.
When i try to change the settings from the Embedded Web server interface to WPA2 PSK and AES, the wireless drops and the printer is not connected to the wireless anymore.

How to re-set up WEP security on a WRT100

I'm visiting at my aunt's house and her Linksys was not working properly, so I reset it to factory default, and it's working now, except now I cannot seem to find the how-to page on how to set up the WEP security again (or another security variation...whatever is appropriate now for a home-based router). Can someone sent me the url for instructions on how to do this? And is it crazy to try doing this without an ethernet cable connecting the laptop to her router? Thanks!
Solved!
Go to Solution.

For you to be able to set up the security, it is imperative that you connect a cable from a computer to the router. But this is just temporary unless you are finished changing all the settings. You can do it wirelessly, but you will have to re-login again and again to the set up page because you will be disconnected every time you change a setting. Please refer to the link below:

Difference between WEP, WPA, and WPA2 and better suggestion to use for shared family users

What is the difference between WEP, WPA, and WPA2? My router is set up on my family PC and connected to a modem so I access Wi-fi through my laptop and my sister has a laptop too and uses our family network to get internet. I just set up a WPA today, so will we all be able to get internet (along with my family using the pc, and my sis on her laptop, even at the same time) protected? (like nobody else using our network)

Wired Equivalent Privacy, commonly called WEP is 802.11's first hardware form of security where both the WAP and the user are configured with an encryption key of either 64 bits or 128 bits in HEX. So when the user attempts to authenticate, the AP issues a random challenge. The user then returns the challenge, encrypted with the key. The AP decrypts this challenge and if it matches the original the client is authenticated. The problem with WEP is that the key is static, which means with a little time and the right tool a hacker could use reverse-engineering to derive the encryption key. It is important to note that this process does affect the transmission speed.
WPA builds upon WEP, making it more secure by adding extra security algorithms and mechanisms to fight intrusion.
WiFi Protected Access (WPA) is the new security standard adopted by the WiFi Alliance consortium. WiFi compliance ensures interoperability between different manufacturer’s equipment.WPA delivers a level of security way beyond anything that WEP can offer, bridges the gap between WEP and 802.11i networks, and has the advantage that the firmware in older equipment may be upgradeable.
WPA2 is based upon the Institute for Electrical and Electronics Engineers’ (IEEE) 802.11i amendment to the 802.11 standard, which was ratified on July 29, 2004. The primary difference between WPA and WPA2 is that WPA2 uses a more advanced encryption technique called AES (Advanced Encryption Standard), allowing for compliance with FIPS140-2 government security requirements.
