I was wondering what is the router performance decrease when using encryption?
For instance the CISCO2911 has 180.73Mbps half duplex switching performance, what would be more or less the decrease in performance if I use encryption?
Is it possible to have a 64 bit and 128 bit encryption key activated on the same router at the same time - one for laptop and one for wireless printer

Under Security "Authencation Type" there is WEP, WPA, WPA-2, WPA-AUTO. What are these settings for and which do I choose for a home wireless net work?
View 3 Replies View RelatedI'm having a very difficult time getting my WRT54GS to work with my Westell 6100 modem. I've been bouncing around gathering info, and what I've learned is that the goofy way CenturyLink tech support told me to hook up my old wired router (modem line into outgoing (LAN) router port) is because the Westell 6100 is a "smart modem/router". Therefore, when I run the Linksys setup CD, it sees the modem as a router, and won't properly configure. I've also learned that the Westell modem can be "dumbed down" into simply a modem by putting it into "bridge mode", which is where I'm at right now - trying to get it reset to factory defaults and resetting the connection type from PPPoE to Bridge. In the meantime, I also reset the WRT54GS to factory defaults, and now I've got another problem: the router will not allow me to set up encryption. The default setting is "Disabled", and when I click the down arrow and try to make any selection at all (preferred selection is WPA2 Personal), it reverts to Disabled. I've also tried to change the router's IP address to 192.168.2.1 (and alternately to 192.168.1.253), so it won't conflict with the modem's IP, and it freezes up every time I try.
View 1 Replies View RelatedFactory default settings of my WRT54GS encryption are Disabled. When I try to enable WPA Personal encryption (>Wireless, Wireless Security), it reverts back to Disabled as soon as I make the selection. >Administration, >Wireless, >Encryption Function is Disabled.When I had this router set up at another location with another ISP, this was never an issue. How do I get the encryption function to be enabled?

View 5 Replies View RelatedMy router is running the stock 1.21 firmware and it has been fine for almost a year before the wireless suddenly stopped working. I reset the router and restored my previous configuration. After the reboot, the SSID is visible and I can connect to it but there is no internet connection. Also the router becomes unresponsive, i.e. timeout trying to access the router configuration page. After trying out different settings it seems that enabling WPA2+AES is the cause.In the mean time, I am running an open wireless network and everything seems fine. Is the hardware faulty? I am reluctant to update the firmware because of a negative experience with another router (same model).

View 4 Replies View RelatedI run my virgin broadband through an old NTL modem and a Belkin router. I haveit all attached to a computer in my study along with a new 6TB Buffalo Nas drive. The computer has GIGABIT LAN. I use Belkin powerline units to relay the network around the house. In my lounge i have a blu ray player, AV amp and my sky box attached to the network via the Belkin powerline units and all run ok. This week i have added a Cambridge audio streamer but i am suffering now from a lot of dropouts and network failures escpecially when trying to stream music from my NAS. all seem to be set up correctly as per the manuals. I have spent a lot on this unit specificallly to stream my music so this is really important to get working correctly The powerline units can flash blue (fast ) or orange (slower) but i only see the orange light .My local dealer says i need to upgrade my Modem/Router and has suggested an ASUS RT-N66U which I understand is a modern 2.5/5ghz model . he says my system is overloaded
A few questions.
Is this a suitable modem for me to use on my Virgin cable broadband? (apparently there are two alternatives types of modem/router)
Is there a better alternative unit ?
Could there be another cause for my problems and if so how do i diagnose them ?
1. WUMC710 data rates fluctuate extremly under OSX 10.8.2 with an iMac 27" . Meaning, one second, I have about 9 mb/s in the other second, I have 20 mb/s. It is fluctuating permenently. When I use another bridge, eg. ASUS EA-N66, the datarate is very stable and I can see no major fluctuation.
2. The overall datarate when using the WUMC710 with OSX is about 50% less, than with Windows7. I have windows 7 installed as a virtual machine on my iMac. When transfering a file to my NAS device, under OSX, I have an average datarate of 18 mb/s. When I transfer the exact same file with win 7 as a virtual machine on this iMac, I have 35mb/s on average!!!!! When I use another bridge, eg. ASUS EA-N66, the datarate is the same on OSX and on windows.
3. The low datarate and the fluctuations also appear in combination with an other router, so it must be something with the WUMC710. I tested it with the EA6500 and ASUS RT-AC66U.
What I have done:
- Tested with two other adatpers (ASUS EA-N66 and built in Apple Airport). Both show constant and high datarates, so the problems only appear with the WUMC710.
- Tested with another router. The low datarate and the fluctuations also appear in combination with an other router, so it must be something with the WUMC710. I tested it with the EA6500 and ASUS RT-AC66U.
- Tested with another OSX device. Same problems with an iMac 27" and with a MacBook Pro. So not a specific problem with one apple device
- Tested with another windows device. Under windows, the WUMC710 shows way better performance and nearly no flucuations in data rates.As I have tested other Wireless adapters, combinations with other routers and other OSX/Win devices and the problems are alyways the same, It must be a bug of the WUMC710. Performance under OSX 10.8.2 is slow and not constant.
I'm running a WRT54G as my main router with an old Buffalo router (125g I think) as a repeater. Both are running DD-WRT.
I'm looking at upgrading to a pair of netgear 3700's; also capable of DD-WRT. These have several times the RAM and ROM of the stuff I'm running now. The processor is also about 3.5 times faster as well.
If I do this, should I expect to see an decrease in ping (gaming) or an increase in general performance of the network? Also, there is a lot of video streaming going on, but little/no torrenting. We only run about 5-6 devices on the wireless network, but it has to span 4 floors.
What is the Cisco 1921 router performance if connected with 2 Giga Ethernet port? What is the performance if enable GRE tunnel ?
View 2 Replies View RelatedI have a new 861 router which I have connected to my home broadband cable modem. Got it all working okay and I have access to the Internet but its not as fast as it is if I connect my laptop to the modem.
My Internet is 60mb (was 100 but I downgraded). When I cannot my laptop directly to the cable modem, I get 60mb download speed on speedtest.net If I connect the router's WAN port back to the modem then I roughly get about 40mb, sometimes even 50.
I do not have any IOS firewall configured on the router, just basic ACLs to stop SSH and TELNET from public networks. If I do enable firewall then my Internet connection halves itself. I have read around that this is the case with ios firewalls on these small routers so I've disabled the firewall but I still don't know why I cannot get full Internet speed.
I am in a situation where I share internet access with roommates. We have a Gateway which is conected to the provider and which delivers ethernet and WiFi signal.
In order to isolate myself from my roomates and to protect my network connection, both wired and WiFi, I would like to plug in the Ethernet cable I get from the Gateway to my router, and then configure my router's firewall and WiFi enctryption to maximize my safety.
However, I am having some problems. I have already configured the router as "router" and not "Gateway" and I am trying to assign it an IP address different from the default one, which is the one the gateway has, and a ranger of DHCP IP's, also different from those of the Gateway. In other words, 192.1681.N.1 for the router and start from there.
I'm experiencing quite a slow vpn performance. I've tested different scenarios.* Windows XP with built-ín pptp client and Shrew ipsec client* Linux built-in pptp* wireless and wired connections?

View 1 Replies View RelatedI recently purchased an EA4500. It started out working really well, but recently I noticed that my speed on my iPhone and iPad has dropped significantly. When I'm in my office where the router is set up, I'm getting around 15 to 20 mb download speed and 5+ upload speed. When I go to my living room about 40 feet away my speed drops to 1mb down and less than 1 up. I expect to see a drop in my performance the further away I get from the router, but this seems really unacceptable to me.

View 4 Replies View RelatedWe have a remote site connected to ADSL line with a Cisco 887VA router attached. This has been working fine for the last couple of months. However, recently, the site have started to complain of performance issues (network slow, applications disconnecting, etc)Looking on the router, we can see evidence of packet loss/timeouts from a simple ping to the internet e.g. [code]
However, we have logged the fault with our service provider and they return all line tests as clear but what is particularly strange is that they also report “and the SNR Margins are well within threshold levels (Upstream 11.5 and Downstream 15.0)” which, unless I’m misunderstanding something, seems to be completely different from what the router itself is reporting.Is there a reason why the service provider’s stats for Noise Margin would appear to be so different from what the router is reporting?
Im getting really poor performance on my 1841, my intial thoughts was a duplex mismatch however although im getting a few CRC errors (root cause unknown at this point) not enough to suggest that the this is the issue.

View 6 Replies View RelatedI have EA4500 acting as a router on domainless all-Windows network of two XP machines.Unfortunately, EA4500 aggressively grabs the role of the Master Browser (I am talking about Computer Browser Service) on the network (regardless in which order you power the devices up) and then doesn't serve as a working Master Browser - both Windows machines stop listing the network computers in the "Network Neighborhood" and incur massive timeouts when attempting to view the listing.A quick look with 'browstat.exe status' reveals that indeed the router has announced itself as a Master Browser device, but returns errors when you query it.Quite predictably, without the router, both machinces figure out amongst each other who will be the Master Browser and everything works fine. The problems begin only when you add the router to the network.
1) Is there any way to make EA4500 work like a full-blown Master Browser (the one that not only announces itself, but also serves as such)? having a Master Browser integrated in "always-on" router would really improve the predictability of the network.
2) If not, is there any way to disable the Master Browser on EA4500? For now I managed to achieve that by assigning the router to different workgroup name, but this is lame, as I now can't connect a disk storage to the router and use it within the same workgroup.
I currently upgraded to E3200 wireless router from my previous WRT610. I use itunes/apple airport express to play music located on a Buffalo NAS (LAN connection to E3200) on my home stereo.

View 2 Replies View RelatedI've recently acquired a Linksys E1200 router--which is more than a week old--from the recommendation of a friend of mine. The service is great and all, but the one thing that frequently bothers me is the seeming constant instability of my router's model. There are moments when the router performs smoothly, but there is as much an instance because the router doesn't seem to work at all even when the lights (and the accompanying connection) on my modem seem to be working in good order.
I know that a router will always have its problems, but this is really a constant problem with the E1200; and if so, if there's any way possible on how I can be able to "stabilize" the said router's performance.
I've bought a E4200 router because of it's "maximum performance". With the normal settings i have a wireless range of maximum 10 m in the building. after 5m I've got a low signal.I tested a cheap Netgear-router, which had the same range as the E4200 a 125 Euro.Is my E4200 broke or is it just a bad buy? The settings are standard (that shouldn't be the problem, I guess!?)
