R195W Dropping Connections - Lost Customer

We have a customer on an R195W. They explained this morning that their WiFi devices all lose Internet connectivity with this router periodically. This replaced an R200 that was there previously, but couldn't meet their speed of their service. 

We are losing this customer because of the performance of the R-Series routers. They are switching to another service, and do not have interest in troubleshooting this further for us. 

I am switching them back to the R200 which should put them back to normal, but limited speed. 

Please, Cambium, there must be a way to provide a recommended configuration for each of the R-Series routers. Troubleshooting these things is getting tiresome. Reading the forums to find tweaks to avoid issues does not feel like these meet the price premium they have. 

Thank you, Chris

I have forwarded this to the support team and the product team.

I had the exact same issue, lost a customer and ill never get them back...cambium needs to address this issue.

It's been over 2 years, I don't think anything is going to change until a new hardware revision is made in house. I feel like there's both hardware and software issues with these routers.

Ray, this isnt something new and we have been asking for help with this for months. It needs to be brought up to PLM for immediate suppoort.

Release 4.7 is currently undergoing system test and is expected to be made available in a matter of weeks.  Release 4.7 addresses the disconnect issues many of you have been experiencing.   We will inform you as soon as the release is available.

Chuck, 

Does this fix the R195W only, or the entire R-Series lineup? 

Has anyone seen or tried this suggestion to put up an IP access control list on the R195W ?

I do not have any of these units but I am looking to get some to test, was told about this issue from my distributor…and then found this article:

It is always a good idea to restrict access across WAN to only known hosts, hence the provided suggestion should be helpful in many cases.

thanks

These problems have continued and have not been resolved in any way by the newer firmware (tested most recently on 4.7.1-R4). We have been trying multiple configuration variations, but with limited success.

We have lost 3 more customers who claim WiFi problems as the reason.

Cambium, we standardized on the R-Series routers when they were C3-VoIP units. We are now noticing problems with R190V, R190W, and R195W routers. We have stuck with this for a long time, but are wearing thin. Please, what steps are being taken to provide us with standardized working configurations?

I’m preparing to switch to another platform. I would really prefer for the Cambium equipment to just work, but there has been such little progress here, I am having a hard time seeing a path forward.

[Further, the R195P was just released at a $120 price point! It isn’t AX or even Wave-2, and is already more expensive than the tried-and-true reputable competition. Is this the path forward to expect? This suggests when a Wave-2 or AX product is actually released, it will be even more expensive. Please, I’m ready to be convinced to stay. I want everything rolled right into cnMaestro like we have currently… but it has to work.]

What should I do? How do I get these to work?

Any update on this? The R195W has been much better than previous routers and 4.7.1-R4 is better but wifi still drops. Customers haven’t complained too much but some customers are noticing. I just installed a router for my parents and the family really beat the hell out of it over Thanksgiving and it failed in a very superb fashion. The wifi network would run fine, then drop, drop, stream fails, comes back, repeat. It might run great for another 20 minutes and crap again. This screams memory leak or maybe driver issue. It could also scream crap hardware. Calix has been waiting for me to get off the pot on this so maybe it’s time. I would rather stay with Cambium but this needs resolved immediately (like 2 weeks guys),

Hi Matt,

Can you drop me an email at ashutosh.datta[at]cambiumnetworks.com so that we can talk about this issue.

Every day my list starts with “Order Calix gear”, and I keep putting it off hoping for a fantastic repair from Cambium… or a fantastic replacement, or something. I just got an R195P to test despite the really high price for a Wave 1 product. It has different internal hardware, but it had the same problems as the R190V and R195W. For one customer with regular problems, I just added a UniFi AP, and most of the problems went away.

We are experiencing same issue even after the latest update 4.7.1-R4. Very frustrating!
