Premier Speeds

I need a bit of help here; I have COX High Speed Internet Premier service and a Wireless Netgear JWDR2000 router that was connected to a SB5101(D2) modem (very old). The Download speed has been 12-16 Mbps and the Upload speed was 5-6 Mbps, since this was very slow for Premier service I bought and installed a SB6141 modem (D3). The speeds now are about 12 Mbps for Download and 12 Mbps for Upload.  This too is very slow for this service; can you help with this problem?

 

Thanks,

JRS

I don't see the 6141 active on your account did you ever switch the service to the new modem?

Yes, I am using that connection now and I see it active and the correct MAC address on the COX Devices display for my account.

I see it now.  The firmware does appear to be correct and I'm not seeing any obvious indication of an issue from this end.  Are you able to try testing without the router to see if you get different speeds that way?

I will try and see what happens

Direct connected to the modem renders 32 down and 9 up

So what I think I know, connecting a wired connection (100Mbps) to either the SB6141 or to one of the wired ports of my WDR2000 router renders much better speeds than via the wireless connection on my "Dell" laptop that has a "Intel(R) Centrino(R) Wireless-N 1030" and should support the expected speeds of the Premier service. I tried another laptop "old HP" wireless connection that only supports 802.11b/g and got the same results, though I noticed that the wireless connection speed was 54 Mbps,I then looked at the Dell and I would have expected it to be connected at ~100 Mbps but it was also at 54 Mbps which I suppose is 802.11g type speed.

The WDR2000 set up should support speeds up to 145 Mbps but doesn't seem to be, I did check on the Intel(R) Centrino(R) Wireless-N 1030 on the Dell site and it says:

 

 Data Rate will not Exceed 54 Mbps 

 

A user may report they are using the Wired Equivalent Privacy (WEP) or Temporal Key Integrity Protocol (TKIP) security protocol along with an Intel Wireless N adapter and reaching a data rate of only 54 Mbps.
The IEEE 802.11n draft prohibits using high throughput with WEP or TKIP as the unicast cipher. If either of these encryption methods are used, the data rate will drop to 54 Mbps. 802.11n requires WPA2-AES or WPA2-TKIP enabled to operate at 802.11n rates. Newer Intel wireless adapter client drivers connect using a legacy IEEE 802.11g connection rather than failing to connect altogether, which complies with the IEEE 802.11n draft.

Since I have ,for no good reason, chosen to use WEP encryption do you suppose that this could be keeping me from reaching the expected Premier speeds.

I know this is a bit longwinded and shying a bit from the modem but your input would be appreciated.

Well, before you go too deep into it, I just made a correction to your account that needed to be made after the 6141 was provisioned but had been overlooked, which happens all too often. I just hadn't had a chance to hit this thread back yet, so if you retested in the last hour or so, that may help explain some of the difference.
However, you're always going to want to use WPA anyway. I've cracked people's WEP keys before just to show them I could.

I tested just now and it's still about 12 Mbps up and down, I'm going to change to WPA from WEP and post my results here for posterity.

I didn't realize you were using WEP.  Keep in mind that is a software encryption that was invented after wireless and thus adds processing over head to both the router and the adapter.  Going to WPA2 is more desirable as how that uses built-in hardware.
