Cisco/Linksys Router Vulnerabilities

Hello,
I have an e3000 wireless router.. I am unable to disable wps on it.
The WPS vulnerability was exposed in December 2011, along with the reaver tool to exploit it.
https://threatpost.com/en_us/blogs/wifi-protected-setup-flaw-can-lead-compromise-router-pins-122711
Why is it that nearly a year later, that there hasn't been a firmware update allowing users to disable wps on their Cisco/Linksys routers?
Some have patches available, but judging by: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=3bccc46248f9417b909e2c1028f6778e_WPS.xml&pid=80&respid=0&snid=1&dispid=0&cpage=search
The majority do not.
Even more astounding is that refurbished models are still available through your homestore:

Why is it that I have to update a major security vulnerability through dd wrt or tomato?
I've bought and recommended Cisco products for a long time.. However, I cannot in good conscience do so any longer.
Why is it that Cisco cannot/will not support products that they have released?

Cisco-Linksys Router and no PPPOA Option for Conne...

Hi all!
New here and just hoping to get some here!
We are using a BT Business hub Router and it is having a few issues with wireless connectivity, so I would like to use another router to see if it is our equipment or if it is the router itself.
I have a Cisco Linksys E1000 Router and after looking at the BT router I can see that the connection type is set to PPPOA with a username and password. I do know the username and password so that isnt an issue, however on the Cisco router there is no option for PPPOA, the only options are:
Static IP, DHCP, PPPoE, PPTP, L2TP, and BigPond
There is a connection in the back of the cisco router for the ADSL cable, I was just wondering if there is a way to work around this?
Thanks very much!!

I am sure you will get help there when someone has time.

Hooking up AE through ethernet to cisco/linksys router

Apologies if this is a repeat, tried searching.
I used to connect my AE to a Belkin router using a "uplink" button on the back of the router. Everything worked till the Belkin fried one hot day.
Got a new router - Cisco/Linksys "Etherfast" Cable/DSL router (non wireless) that does not have an "uplink" button like the Belkin did. Thought AE would be smart enough to adapt. Not so apparently.
Simply plugged the AE into the new router just like the old one. I can connect to the routers setup screen wirelessly through the AE but cannot access the internet, which is connected to the router through my cable modem.
If I plug the AE directly into the cable modem I do get the internet.
Tried setting the AE to "bridge" mode with no luck. But not sure if I need to configure the DNS settings. Not sure how to do that.
I've done hard/soft resets.
Do I need a crossover cable? Apple says the AE does not require a crossover.
thanks for any helpful info!

It is always a good idea to perform a complete power recycle of your networking equipment when changing components.
Please try the following:
o Power-down the Cisco, AirPort Express Base Station (AX), and computer(s); wait at least 10-15 minutes. Note: Power-down order is not critical.
o Power-up the Cisco; wait at least 10-15 minutes.
o Plug-in the AX; wait at least 5-10 minutes.
o Power-up the computer(s).
Simply plugged the AE into the new router just like the old one. I can connect to the routers setup screen wirelessly through the AE but cannot access the internet, which is connected to the router through my cable modem.
By this statement, if you mean a wireless client connected to the AX, can access the Cisco's web-based administration pages, then the AX is (at least) getting the proper Private IP address from the Cisco gateway ... and, if this same wireless client cannot access the Internet, it is usually indicative that it is not getting all the proper IP address information from the Cisco ... specifically the DNS IP address information.
Hopefully, the power recycle will fix this.
Tried setting the AE to "bridge" mode with no luck. But not sure if I need to configure the DNS settings. Not sure how to do that.
Bridge mode would be the correct setting for a router that is downstream of another. In this mode, the AX will allow the Cisco to provide both the NAT & DHCP services for the entire network ... either wired clients connected to the Cisco or wireless clients connected to the AX.
Do I need a crossover cable? Apple says the AE does not require a crossover.
No, as both routers are capable of working with either crossover or straight-through type cabling.

Airport with Cisco / Linksys E4200 Router

Hi, I have not been able to find a straight forward answer so i'm posting this.
I'm looking to switch my Linksys router over to N wireless, vs N and G or Just G- Not sure what it is now. I don't have great connection on my 2nd floor, with my Linksys router on the first floor. I want to use this as a bridge (instead of the RE1000), because i want the 5ghz, and AirPlay.
Can i use this as a plug and play bridge? I just want it to extend the signal, and be able to use airplay. No new network.
Some info i thought i would add:
ISP Cat 5 or 6? to Modem to Router (E4200)
Ping at 64 bytes
WPA2/WPA Mixed Mode Security
Thanks in advance.

No you will not be able to use an AirPort to extend the wireless range of the Cisco/Linksys router if they will be interconnected by wireless. However, if they can be interconnected by wire, you could configure them for a roaming network.

Does the airport time capsule eliminate the need for my cisco linksys wireless router?

does the airport time capsule eliminate the need for my cisco linksys wireless router?

I understand that your network now looks like this:
Modem > Security Router > Cisco/Linksys router > Devices
If you do not want to use the Cisco/Linksys router and use a Time Capsule instead, then your network would look like this:
Modem > Security Router > Time Capsule > Devices

TS3742 Installed Cisco Linksys VUSB. Now my MacBook Air restarts and I get a kernel panic

Bought a new Cisco Linksys router a few weeks ago. Had to install their VUSB to manage the peripherals. Now I keep getting this panic message and my MB Air restarts whenever I log out. How do I fix this?

Same issue here.
If Cisco VUSB is running (in the dock) when the Macbook Air goes to sleep, when it awakens a kernel panic occurs every time. Now I've had to set Cisco VUSB to not launch upon startup to ensure I don't forget about it when putting my Macbook Air to sleep. Very annoying.
Thread on CISCO\Linksys forums: http://community.linksys.com/t5/Wireless-Routers/VUSB-OS-X-10-8-2-and-Auto-Conne ct/td-p/620126
I'm on 10.8.4... and this is Cisco VUSB 1.2.0 (SXUPTP Driver 1.10.0).

WRT54G2 re-directing search to Cisco Linksys Websearch powered by Yahoo

The linksys WRT54G2 has been a disappointment thus far. One of the most annoying "features" is it hijacking url based searches to Cisco Linksys Websearch powered by Yahoo. This is not a browser or computer setting, as it happens with any computer/browser connected to the network. It appears to be at the router level, but I cannot find any settings that would indicate where I can turn this annoying service off. Any suggestions? If it can't be remedied I will, unfortunately, be selling the router and buying a non-Linksys product.

The problem is assocaited with using the Cisco linksys router. I'm not clear what you mean. Plugging in the internet connection directly to the computer via ethernet bypasses the linksys router, and pages are no longer hijacked to Cisco Linksys Websearch.
I take it no on else has experienced this hijacking? This is a problem since the latest firmware update. It is a serious enough problem for me that I will have no choice but to by another manufacturer's product if this can't be remedied.

Cisco Linksys E1000 - Lag Spike about every 10 seconds.

Hello,
Hopefully this is the right place to ask such a question. I recently purchased a Cisco Linksys router, as I was having problems with the main connection and my computer. The router works almost fine and acts as a bridge between the original router, and my computer.
I have a Westell Versalink plugged into the DSL phone cord. The Versalink is connected to my Cisco router, and the Cisco router is connected to my computer... All using cables.
Basically, it's Versalink -> Cisco -> Computer.
It works almost great, except I keep receiving huge lag spikes every 10 seconds, when trying to run something that requires a constant connection. (In my case, a game. It will lag every 10 seconds.)
I'm not sure I setup the Cisco router to properly work the way I want it to, thus the lag.
It used to be far worse, but I setup the PPoP login on the Cisco router independent of the fact that it's already connected on the Versalink.
I need some advice on how to eliminate this lag so I can get a steady and smooth connection.
Before anyone starts giving me Wireless advice, this has NOTHING to do with the Wireless portion, that works fine. (But probably would experience the same lag.)
This is happening regardless, and I need it fixed.
Yet again, I'll type out my layout here:
DSL / Phone -> Versalink -> Cisco Router -> Computer
I believe the problem exists in the Cisco router. I'm amazed that I was even able to get it to work how I did to begin with. However, I need some additional help.
Any help would be appreciated. Thank you!

Ice Sage,
I would do a little more research on the internet regarding ALL Cisco Linksys routers... the issue you are seeing is normal of thier routers right now.. and one they have not been willing to fix... The Linksys router you have ... in reality is actually the WRT160N with a few tweaks in the firmware... If you look at the specs, the E1000 is not the best router to play your video games with or HD Movies... you really wanted the E3000
BUT .... that also has that same issue as well but more pronounced... as well as over heating... if you take your router off you will see the lag goes away.

Cisco Linksys WE-4200 compatible?

Are either Airport Express or Apple TV compatible with the latest Cisco Linksys router?

Will an Airport Express connect wirelessly? I would like to stream music to the second floor system.
Yes, it will "join a wireless network".
Will it connect via ethernet to stream music to the first floor home theater system?
Yes, if you stream to an AirPort Express. it will "connect using ethernet"
Would there be a time lag between the same music played wirelessly and wired at the same time?
Probably
Will Airport express work on my smal third floor hooking in via ethernet but then acting as a wireless extender?
Yes, if you configure it in Bridge Mode to "create a wireless network" using the same wireless network name, security and password as the "main" wireless network
How about Apple TV instead. Would there be a better chance of connecting wired and wirelessly than with the Airport Express?
Strongly recommend an Etherent connection if you plan to stream any kind of high-definition video material. You will need to remember that the Apple TV only has an HDMI output and optical audio out, so your audio video receiver, or television etc at the Apple TV end will need to have that capability.

Need help configuring Cisco/Linksys wireless router to extend wi-fi signal to living room

My U-verse wireless gateway is in the back of our house. We live in an old 1920's home with solid wood walls. For our macbooks, we get a pretty decent signal, but my wife's iPad 2 get's poor wi-fi speeds. I bought a Cisco/Linksys WRT160N wireless N broadband router. I have a wired connection in my living room (going to a 4 port switch) then connected to my DVR. I tried hooking up the new router but ended up getting no signal on the iPad. In fact, it caused other issues. I ended up disconnecting it and re-booting my gateway. All came back fine. This wireless router replaces a similar unit that went out in after a power failure, so I know this can be done, but I forget exactly how I confiured the old one. I would like it to "extend" my signal to the living room, but I am also willing to create a new network (different SSID). Do I need to turn of DHCP? Are there any web sites that can assist me in configuring the router? I wish I didn't have to deal with this. The signal from the RG is great when you are in the back room (20+ down). But my wife gets about 3 down on her iPad in the living room. Thanks in advance.

Hi ,
I was doing some research on how this can be done. It does not appear there is an option in the Cisco router to set it up as an access point, but there are several options you can do to extend your network.
The first thing you can do is just set it up as a router behind router setup, and you will just have two separate networks. Make sure the DHCP pool does not conflict with the U-verse's gateway of 192.168.1.x.
The second thing you can do is connect the Ethernet cable to one of the LAN ports on your Cisco router instead of using the internet port. This should make it work like a smart switch.
With both setups, you want to probably change the SSID, network key, and wireless security settings to the same thing for wireless roaming abilities. That way, anyone that configures their wireless connection will be connected to both networks. Just make sure the wireless channels are not the same, and I would suggest having them at least 5 apart.
Hope this helps.

HP Officejet Pro 8500a prints slowly over wireless on Cisco Linksys Smart Wi-Fi Router EA6500

I have the HP Officejet Pro 8500a. I recenrly change my wiress router to the Cisco Linksys Smart Wi-Fi Router EA6500.
Nearly every time I print, the documement remains "pending" for at least several minutes, sometimes as long as 20, until it finally starts printing. Once it starts printing, the document is printed quickly.
It doesn't matter the size of the document and the time it remains "pending." I've done test pages with just the word "test" in a Microsoft Word document, and it will remain in "pending" for well over five minutes.
If I print over the USB cord, there are no delays.
I need help. I can't figure out how to remedy this long delay when printing wirelessly.
On a side note in case this is helpful, the Linksys router does have a priority setting where you can select up to three devices for priority access (faster connection?), which seems to be more for bandwidth-intensive devices. I tried adding both the laptop I'm printing from and the printer to this priority list, but that did not improve the print connection speed.
Advice please! Thank you.

Hi Jim-Gr,
I understand you have an Officejet 8500A that has started printing very slowly after switching routers. I'm sorry to hear this has happened but will certainly do my best to assist you.
I appreciate you advising that you have tried connecting the printer via USB and it does make a huge difference. I'm also assuming your previous router didn't go this slowly either. With the things you have tried, my assumption is that it's a setting in the router that needs to be changed. If you're not sure how to change things in your router you can generally call the router company and they will walk you through it.
First you will want to ask them if there are any firmware updates for your router, if there are have them perform the update. If it is up to date already then have them make sure your router is broadcasting at a frequency of 2.4 GHz as that's the only frequency the printer works with.
Second, you will want to make sure the following ports are open:
UDP: 427, 161, 137, 138
TCP: 9100, 9220, 9500, 137, 139, 427
Once all of this is updated, then I would suggest you power cycle everything (turn off the printer and the PC, pull the power on the router for 30 seconds and then turn the other two back on once lights are back to normal) and try again. This should allow your printing speed to go back to normal
Hope this helps, have a great day!

No longer using Linksys router. Should I uninstall Cisco LEAP, PEAP, and EAP?

Should I uninstall the Cisco LEAP, PEAP, and EAP programs if I am no longer using a Linksys router? I am replacing with an Asus router.
thanks,
KG

Hi! It's best to uninstall them all if you are not going to use them for the sake of freeing some memory on your computer. Should you change your mind and get a new Linksys router one of these days, I am sure it will come with its own installation software anyway.

I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too..

I have a Cisco/Linksys WRT-54G wireless router and 2 Airport Extremes (the small ones that plug directly into the wall). Is it possible to extend the network from the router using these two AEs? I have a DVD player and Ext HD plugged into the router too. Any ideas? I'm guessing the only way is to do what I've seen in these community pages which states that it can be done but it will drop the bandwidth by 50%. Thoughts?? Thanks!

The Cisco/Linksys WRT-54G was one of the very few routers said to be compatible with Apple's implementation of WDS (Wireless Distribution System) settings.
The info that I have on file indicates that only the WRT-54G versions 4 and under were compatible, so that would be one bridge to cross.
Even if you find that your Cisco/Linksys might be the right version, Apple never published instructions on how to configure the Express devices with other manufactures, so users were left to their own devices to try to figure out how to get things working. Apple's instructions to connect to other Apple devices are in the link below:
WDS network
If you were hoping to use 2 Express devices in this type of configuration...even if it works...the bandwidth penalties will be extremely severe.
The first Express drops the bandwidth (and speed) on the entire network in half and the second halves everything again. So, the result, in effect would be a "g" wireless network running at 25% speed. Few users would consider installing this type of network.
At this point, it becomes one of those things where the fact that you might be able to do something does not mean that there would be much value in doing so. But, it is your decision to decide if you want to try to proceed.

Cisco Linksys E1000 Connection to Verizon Router

OK here is the situation. I spent two with a verizon tech on the following issue.
I have new PC, windows 7, that I have connected via wireless Trendnet 150Mbps Mini Wireless N USB Adapater. The spped is less than 5Mbps download and upload. My verizon plan is 25Mbps. In the end it was determine that the verizon technology is g format and the adapter is n technology. The computer directly hard wired to the verizon router gets 30Mbps speed.
Bought a Cisco Linksys E1000 N technology router to connect to the Verizon router.
Connected to router and could not get any internet even though the signal strength was extremely good.
Got any suggestion on how to get this to work.
I am dying with this problem,

When connecting the E1000 router to your fios one, i would use one of the 4 LAN ports and not the WAN port to make the Ethernet connection between the two. Then go into the router web page of the E1000 (192.168.1.X) and make sure that the DHCP server is disabled.
Now for your speed problem. Even with wireless G you should still be fine as it can tranfer much faster than 5Mbps. The problem could be that the Trendnet usb adapter has a pretty tiny radio and your connection slows way down as you move away from the the wifi source.

Linksys router with cisco switch

Hello everyone,
Just wondering if i can connect a cisco switch to my linksys router. Any info will be helpful. Thanks.

Well, you should be more specific what info you need.
Your question is answered with: yes, you connect a cisco switch to a linksys router. You can connect pretty much any ethernet switch or hub to a linksys router.
Beyond that I don't know what you want to know and thus cannot really give you more info.
