The best way I've found to fix any problem with Comcast is to not call Comcast Customer Service......EVER. Anyways, with that being said If you can eventually reach a rep. who has any technical knowledge at all (I talked with several Level 1 reps and one Level 2 who was useless and had no understanding of his job unless it was written in an faq on his computer screen) then you should definitely press for them to REPROVISION the modem. Then End! Now I'm a Level 3 rep. so hopefully Comcast will start paying me since it seems like the customers in the forums are working harder and fixing issues more so than their actual employees. Also, it was the the 8th Level 1 rep I spoke with who fixed the issue. The only person at comcast who has any idea of what they're doing....
But do you think that switch will automatically pick up (all or any) additional IPs (pretty sure they'll be dynamic) assigned to me?
Yes. If you have a residential account, the additional IP's will be dynamically assigned. Only their Business Class customers can get static IP's
and is there a specific switch that I should buy; managed or unmanaged?
It's up to you. It depends on if you need the extra features / control that a managed switch offers;
Buy a swithch that has gigabit ports.
Also, SB8200 has two NIC ports in the back; why are they not picking atleast two separate IPs when I plug two routers in each port.
Comcast currently has the second port disabled via the firmware.
thanks alot for atleast responding to my request,
Hopefully, someone from Comcast team will jump in as well.
Paranoid, thank you for those suggestions.
For all that get this far, issue was solved this morning when on phone with tech. She claims the other help personell was updating a old modem on my account(since removed by this most helpful lady) and she had upgraded the account and correct modem info. After this I saw speeds of up to 232mbps and 12 UL on a 200/10 package. My advice, I prefer chat due to speech issues from a stroke, but bite the bullet and call in, any major issue seem to take that route to get resolved. Thanks to all who offered their input on the issue. Edit to add, these speeds were accomplished with a wireless card capable of the newest AC protocol, with a N adapter, saw close to 100 a increase of 70mbps over my performance plan.
For several weeks now Facebook does not work when using home network. All other sites work fine. Facebook works fine on my phone. it doesn't work on any browser. I have clear all history and cache. I have reset the modem. The only thing I can figure is that Comcast throttles the internet speed and this is why Facebook is unusable. I know Facebook is not very important, but Comcast is extremely expensive and I would prefer that it works.
If all other sites work fine, then it isn't a problem with Comcast, it would be a problem with Facebook. Down at the bottom of the Facebook login page there is a link for Help. You might want to see if they can help you.
It shows here that the retail model SB6141 is still supported;
This has been a very common problem for a while now. The support reps see that the leased modem is EOL and they tell the cutomers that both are......
Yes. Try having the reprovision the modem. Specifically say "roll" and reprovision. Read below;
Call 1-800-comcast and ask a rep to *roll and re-provision* the modem. Also ask them to confirm that the provisioning and account data in their database is correct and complete and that the correct configuration / bootfile for your subscribed to speed tier is being pushed to the modem.
That's still a connectivity problem just waiting to happen. I'm going to post my boilerplate response. If none of it applies, you should book a tech visit.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home.
Good luck with it !
issue solved! It was the XFast LAN cfos software from ASRock. We disabled it and the speeds jumped up over 200mbps. Not sure why it was bottlenecking with the new modem and not the old one nor the daisy chained router. /shrug
Thanks for the feedback.
