    Tweaking cisco 837 on el-nasty ADSL (UK)

    I have used a Homehub2.0 (Yuk) and my spare Netgear DG834Gv5 (not the best but works as a WAP) - both get similar SNR / latency issues - also my sisters line next door is about the same. interface atm0 clock rate aal5 7000000 clock rate aal2 2600000 --> not supported commands on 837 :(...

    Tweaking cisco 837 on el-nasty ADSL (UK)

    So I have a nasty line here (nothing to be done about that until the telecoms provider gets bored with my one letter a week). I have 7.5db at best (and has dropped to 5.5db during peak times). I've already done all I can internally (only the dsl line hooked up, phones in bin, hi grade socket...

    Upgrading Flash in 837-K9

    Perfect thanks :) (all those years in scm and deployment have gone to my head - I have a implementation and roll-out plan already), I guess good habits die hard! I don't suppose anyone knows a cisco supplier in the uk that can get me the one image file I need (my cisco account isn't registered...

    Upgrading Flash in 837-K9

    sorry should have been clearer - currently there is a 4MB flash module and 8MB on-board. I intend to replace the 4MB module with a 16MB module.

    RAID0 and RAID1...?

    My experience with RAID (both home and in enterprise env's) is to TEST TEST TEST. Install a basic OS and some stuff on the arrays, then pull a drive and see what happens next. See how much recovery is possible and the details needed in order to manage it. If possible - always document this...

    Upgrading Flash in 837-K9

    So Ive ordered the 16MB Flash and 16MB DRAM for my 837. I am unable to find a simple guide to the upgrade implementation. I see many 'this is how you fit the ram' guides and thats ok, but nothing stating the best practice for the job. Bear in mind my 837 does not have enough flash on board to...

    Cisco 837 ADSL Dropping intermitantly

    problem 'seems' to be resolved (still have 6db SNR during busy times, and sometimes gets to 8 off-peak) I have a lovely XTE-2005 faceplate and cat5 cable with RJ11's to the router. No other devices/extensions are physically connected to the line. I also had to add dsl noise-margin 3 to the...

    Cisco 837 IOS update

    Cheers - All went well. I've ordered the Ram to go to a later release if I feel like playing some more. now running Version 12.4(12) and thus far so good - I've spent some time on a new config file (to remove the backup dialler) so I'll set about testing it tomorrow perhaps - any comments...

    Cisco 837 IOS update

    Well I do have a WAP at the moment (a nice Linksys). The planned replacement (877w) won't happen until later this year. Currently I am having some stability issues with my line (I am getting thousands of DSL Defect LOM messages (9500 between 1900 and 0430 currently). I've googled the heck...

    Cisco 837 - UK ADSL Config help

    So my router has been stable these past two days until this evening - more disconnects :( I have yet to call my provider as it changes from BT to Virgin on Tuesday anyways. My ping problem seems to have been sorted but I am a bit green still on the config side of things. I wonder if some...

    Cisco 837 IOS update

    Maybe silly (I know the if it ain't broke don't fix it rule), but my 837 is on an older IOS. She also only (currently) has 12MB Flash. Question 1; what are the pitfalls to watch if I go from c837-k9o3y6-mz.123-2.XE4.bin to c837-k9o3sy6-mz.124-12.bin (The latest one I can find as my cisco...

    Cisco 837 ADSL Dropping intermitantly

    Thanks - I never thought there would be anything I could look at on the line. Anything else I can do (my tool set is limited to a voltmeter) - Guess if I had a line tester I could see it? I'll take a look at that box. Otherwise I guess its a call to my telecoms company (currently BT, but will...

    Cisco 837 ADSL Dropping intermitantly

    Hi Folks. I have a Cisco 837 and a BT ADSL line. With the standard BT Homehub all is well (apart from it's config is locked down :( ) So I config'd my cisco to run and its up and good (for a while). Problem is it occasionally drops the DSL connection. (more often when the connection is...
