Re: [Wired] BEFSR41 V1 and V2 Slowness - Explanation
Probably should be noted that specs on the newer, Cisco/Linksys BEFSR41 say 10/100 mb/s. However, I found it curious that, while places like Amazon and Best Buy advertise this router as full-duplex, Cisco does not even mention whether it is full or half in the spec sheet or ANY of their literature on the router. Are we to assume that 100 mb/s can only be achieved at full duplex?
Note that I am talking about the newer router, which is since Cisco bought Linksys, not versions 1 or 2 mentioned above. The latest version is 4.3.
I am in the process of throwing my v2 in the garbage. It has served me fairly well over the past few years (although I find, after reading RB's post above, less than optimally), but began slowing down about a week ago. It has gotten slower on a daily basis until I am to a point where Web page loads take anywhere from 5 minutes to an hour if they are anything other than plain text.
I've made no drastic changes in my network configuration, Internet connection is fine direct from the modem, and my D-Link wireless router (which I'm using now) is working fine as long as I take the BEFSR out of the picture. I have only to conclude the BEFSR is failing, unless someone else has another idea. I have not upgraded the firmware, but, as I say, the router has been working fine for the last 5-6 years. | |

2 edits | Heres something i recently noticed with all the testing i have done on a fairly broken and lossy bresnan cable connection in missoula lately.

In this image im downloading the exact same file: »www.fileshack.com/file_download.x/14564
This is a comparison download between being directly connected to my modem, a Motorola Surfboard SB5100 against a 5-7 year old Linksys BEFSR41 version 2, 1.46.02 firmware router which is then plugged into the modem. The modem has a rock solid steady download, even considering that theres a bit of packetloss out there to be contended with.. in the area of around ~8% at the moment. The router im using is suffering as you can see.. the download took less than half the time when direct plugged into the modem.
Normally i thought of my router as having worked much better than this, but one of three things is happening, either my router is just plain failing, or its not capable of handling the speed (8mbps / 384k) from bresnan or it just cant deal with the packetloss at these speeds. My guess is that its the latter two. I guess im going to need to replace the router if i want to get full speed, and have nicer looking graphs and performance?
EDIT: Did another test, this time when there wasnt any packetloss on the line that i could see. »img504.imageshack.us/img504/9499···0709.jpg. All i can conclude is that it further confirms my suspicions that my router does not handle packetloss very well, notice how much more close to the direct-modem connect download it looks like this time. The first hiccup on the far left was when i actually pressed the save button.. apparently it was downloading in firefox before i actually pressed save and gave it a location. The one in the center was likely some sort of retransmission. | |
