## Questions & Answers

**Q: does it work with Mediacom cable and voice service?**
A: No, T25 is compatible to work only with Comcast Xfinity's cable internet subscription

**Q: Does this model still use the Intel Puma chipset?**
A: It has the PUMA 7 chipset -> the 5,6 & 7 chipset are all vulnerable to the TCP issue -> but PUMA 6 is the most impacted by this issue. But you have to be targeted for it to be an issue and is only really a problem if you do "fast twitch" gaming activities while targeted.  A series of very many small TCP packets can be sent in a way that overwhelms the cable modem's buffers causing latency and jitter to spike to 100-150 ms while being targeted.  There is a test on DSL reports that will test this TCP vulnerability for the PUMA chipset. Intel (chipset owner -> they bought PUMA from Texas Instruments several years ago) they did come out with a patch for this issue after about a year of it being in the wild ->  my understanding is that the patch has been out since mid 2018 and should be pushed down to your modem by your ISP.

I bought this modem (T25) and after having it provisioned by COMCAST/XFINITY  -> I ran the TCP PUMA test and my modem passed without issue & performed just as well as the rental modem. 

You can buy this modem without issue or fear of this PUMA chipset issue...

**Q: my arris tm822r has battery backup, which is great for when power goes out. does this modem have a battery backup?**
A: No, T25 does not has the battery backup but you can use an external UPS power supply in case of power outages

**Q: does it work with cox cable and voice service?**
A: Cox has support for ARRIS / Surfboard TM3402 
here is a list. 
https://www.cox.com/residential/support/cox-certified-cable-modems.html
best bet is to call them and ask.
besides switching to gigablast and getting VoiP is a much better deal. you can actually save some $$ and get crazy speeds..
