Motorola SB4200 Surf Cable Modem Firmware?


Recommended Posts

http://sbmodem.tripod.com/

I upgraded to 0.4.4.2, which was really needed to play AA (that thing would cut off my connection without it) so just follow the steps very carefully and it should work. * It may be best to download all things required and to print the instruction page out *

(I'm in an ex-attbi area, so not sure if it works for other areas)

Well with that current firmware it's known to cause the modem to lose the connection during heavy traffic to the modem, like a lot packets (or whatever it's called) hitting it at once.

AFAIK the SB5100 doesn't have this issue (and neither does the firmware for the SB4200 at 0.4.4.2 and higher)

Depends on what ISP you have, for me being in an ex-attbi area I could upgrade the firmware myself and I did to stop the dropping connection problem.

You could always try the link out I posted above (2nd post) and see if it that will work for you, but I upgraded mine after comcast told me they couldn't so I would call your ISP to see if they can before trying it.

Is a link I found, looks to have a lot of them to download.

No idea on how you can update different versions, I only tried it with 4.4.2 off that site, I suppose you could follow the same steps but switch the firmware with the latest (including changing all things pointed to 4.4.2 to the correct 4.4.5).

It still will be best to either double-check with your ISP or to call and make sure that there will be no problems upgrading the firmware, and make sure not to uncap your modem :p

/edit - also for the SB4200, there are no problems with the 4.4.2 firmware, it runs fine and doesn't disconnect me, so unless you just want the latest their is real no need for anything higher..

You can change the SB firmware if you want to. I currently am running:

Software Version: SB4200-FIBERWARE-V9F4

Hardware Version: 1

MIB Version: II

GUI Version: 1.0

VxWorks Version: 5.3

Though where and how you do it you'll have to figure out on your own. It can either cost money, or take time, depending on what firmware you have installed now.

    • Look up "greed". If you are willing to buy that it's only inflation, I've got a bridge to sell you.

    • Steam Summer Sale 2026 kicks off offering weeks of PC game discounts by Pulasthi Ariyasinghe Every year, one of the biggest events that Valve hosts is the Steam Summer Sale. Now, the 2026 edition has just kicked off, bringing discounts for everything from the newest games and retro gems to all sorts of DLC packs. As always though, PC gaming hordes have managed to shake the servers of Steam just as the sale opened its doors, so expect the prices, store pages, and services to not show up properly for some time till the backend stabilizes. You'll find sales being present, though with minor cuts, for even relatively recently released titles this time. The front page is the place to be for anyone looking for recommendations, with it putting a spotlight on fresh games every day. However, keep in mind that the discounts themselves will not be changing and will remain static throughout the sale. Blockbusters like Clair Obscur Expedition 33, Split Fiction, Red Dead Redemption II, Battlefield 6, Dispatch, Baldur's Gate 3, Resident Evil Requiem, Anno 117, Arc Raiders, Black Ops 7, Kingdom Come: Deliverance II, and much more are currently discounted. Valve has also brought back the special "Deep Discounts" section. While part of this same sale, it only highlights games that are discounted by at least 85%, with some titles even reaching 95% off. Some of the games included here are The Witcher 3: Wild Hunt, Watch Dogs 2, Far Cry 4, Wreckfest, Dragon Ball Xenoverse 2, The Quarry, Ghostwire Tokyo, Call of Duty: Modern Warfare II, and much more for just a few dollars each. The Steam Summer Sale of 2026 will be open for business until July 9, giving everyone two whole weeks to try and keep their wallets closed. If you want to see the biggest highlights, be sure to read our Weekend PC Game Deals special coming this Saturday.

    • Google reshuffles its AI coding team as it struggles to catch Anthropic by Karthik Mudaliar Google is already reorganizing the AI coding “strike team” it created roughly two months ago, as it attempts to find ways to close the gap with Anthropic in one of generative AI’s most commercially important areas. According to The Information, Google DeepMind is expanding the team’s focus to include “midtraining,” rather than concentrating only on coding tools and agents. Midtraining takes place after a model’s broad initial training but before the final stages that prepare it to follow instructions and perform specific tasks. In simple terms, it gives developers another opportunity to expose a model to carefully selected data before it is polished for release. That could help Google improve Gemini’s underlying coding abilities instead of relying only on better prompts, interfaces, or post-training. Previous research has found that midtraining can be particularly effective for code and mathematics, where models must move from general language knowledge to more structured tasks. Google reportedly created the original strike team in April. It was led by Google DeepMind research engineer Sebastian Borgeaud, who previously worked on model pretraining, and focused on complex, long-running programming jobs. Google co-founder Sergey Brin and Google DeepMind chief technology officer Koray Kavukcuoglu were also reportedly involved in the effort. DeepMind researchers were said to believe that Anthropic’s coding tools were outperforming Google’s Gemini models, prompting the company to give the project more attention. Anthropic has made coding a central part of its AI strategy through Claude Code and its Claude model family. The company has continued improving that area, with Claude Opus 4.8 offering upgrades for coding and other agentic tasks, along with the now-unavailable Mythos and Fable models. The reshuffle also comes at a time when Google faces increased competition for AI researchers. Gemini co-lead Noam Shazeer recently announced that he was leaving Google for OpenAI, while two other researchers who contributed to Gemini and DeepMind projects are reportedly preparing to join Anthropic. It remains unclear whether the reorganized team will produce a new public Gemini model or developer product. No release date, team size, or specific performance target has been disclosed.
