Software Ubiquiti

[Regulo Akers]

Ihave been able to create a vpn tunnel between a PA 3020 and an Cisco ASA 5505, but I am having issues getting a tunnel to come up on a ubiquiti wireless connection. I have checked and the wireless is working fine, it worked before I replaced my cisco asa 5510. Any idea what to check would be helpfull

Are you able to see any VPN related logs in PAN firewall under Monitor >> System: The system LOGS should show Phase-I and Phase-II negotiation information in details. No I do not see any VPN information in the logs for the wireless

Hey guys, first post here. I've been using Ubiquiti products for the last few years, and lately I have been having loads of problems. Problems range from low throughput to CPE radios dropping off of the AP's. They've been having a lot of firmware issues lately, and it seems like they just can't get anything ironed out, and they rely on us to work out the bugs for them.

Unfortunately ubnt is not much help with any of their support, and we've been having too many frustrated customers calling in and cancelling service to due buggy firmware and low throughput issues. We have one sector that is also dropping subscribers randomly for no apparent reason, and we cannot get the issue resolved no matter what we do (replace hardware, firmware, cabling, power, etc.). I'm at the point of possibly swapping this AP and subcribers to a Cambium ePMP1000 sector and Force 200 radios to start, and see if any of my issues go away and make for a better user experience.

I see that they sell the non-synchronized version as well as the synchronized version of the ePMP1000 radio, along with a much higher price for the synced version. Can anyone let me know how much improvement I could possibly see in a somewhat noisy environment between the two? Also, we use 3.65 ubnt sectors as well. Does Cambium offer a 3.65 solution at a decent pricepoint? Or should we see about swapping over (or adding) 2.4Ghz AP's as well? We do have quite a bit of tree coverage, and that is our biggest downfall with 3.65 and 5ghz spectrums.

I too was in the same boat about a year ago. I starting having problems with different things, half baked products, throughput issues, problematic firmware and then end up just throwing up more hardware until it just works. I still deploy UBNT devices today because I just can't justify ripping out what is existing and replacing it with new equipment. As we have grown though I haven't been putting up UBNT, I've been replacing that hardware with EPMP ap's. I now have a mix of UBNT's and EPMP's on my towers and as we replace CPE's we are replacing them with EPMP's. I think every vendor has there +'s and -'s, I think AC1 and AC2 are great, cnmaestro is getting there. For stability and reliability I get far few calls from our EPMP deployments.

I'm not sure how big your environment is but we are over 600 UBNT devices and just surpassed our 100 EPMP install so we have a pretty mixed environment. We are upgrading 2 more towers in the next couple of weeks and installing EPMP AP's. This will run side by side our UBNT deployments until we migrate more of our clients over to the new AP's.

I haven't utilized any of the synced versions because our spectrum is pretty clean where I'm at and I'm not sure how much of a difference it would make. I know that I wouldn't put more than 30 CPE's on a UBNT sector, I have a EPMP sector with over 40+ (we are adding another) and it hasn't missed a beat.

I see that they sell the non-synchronized version as well as the synchronized version of the ePMP1000 radio, along with a much higher price for the synced version. Can anyone let me know how much improvement I could possibly see in a somewhat noisy environment between the two?

If you have just a single ePMP AP then it really won't be any better with Sync. But as soon as you have a full circle of ePMP sectors on a tower, and/or they can see other synced APs in the distance, then sync saves the day.

If you're looking to save the up front cost while you test things, you can run a single sector without sync, but will need to replace the radio with a proper synced AP in the future. You can also look into the ePMP AP lite product - same radio as the ful AP and the ePMP Force 110 synced backhauls, it just limits you to (IIRC) 10 client devices that are allowed to connect. Later you can unlock via license fee & code to make it a full AP.

First of all, welcome to the community! We have a lot of amazing community members here who share thier stories, deployments, experiences and issues. A lot of these members use the full complement of Cambium products and are a fantastic source of information on them.

Regarding your questions. There is virtually no difference, RF performance capability wise, between the Synchronized and the non-synchronized ePMP 1000 radios. The key things that the synchronized radio provides over the non-synchronized are:

3. Dual flash banks. This provides redundancy in case of a failure on one of the flash banks. The GPS radios is typically used as an AP and having that redundancy helps, i.e losing an SM/CPE is not as bad as losing an AP taking down the whole sector!

In terms of interference tolerance, there is no difference between the two radios. The both come with same proprietary TDD MAC with eFortify technology that uses advanced scheduler mechanisms, rate adapt and ARQ algorithms. But if you plan to reuse frequency and reduce self interference, then the GPS radios is key.

Currently there are no plans to offer the ePMP 1000 or ePMP 2000 line in the 3 GHz band. However, Cambium offers this band on the PMP 450 product line. The PMP 450 product line also offers the 900 MHz variant with excellent nLOS and NLOS capabilities.

Sounds like the sync would be the way to go if we would move forward with the 2.4 frequency, which we don't currently use. I know there are other WISP's in the area that do use it, so any way that we can preserve some of the spectrum and offer it ourselves would definitely benefit us and get our proof to install ratio up. As I mentioned earlier, the trees are our worst enemy out here only offering 3.65 and 5ghz.

I do have another stupid question. With Ubiquiti, we have our CPE radios setup in router mode, with a static private IP for the management, and a dhcp server handing out a public IP on a separate vlan. Can you setup the Cambium products this way also, or would I need to modify our setup with this?

ePMP has the option to configure a separate management interface with its own IP address (we use 10.10.#.# for management interfaces). You can also configure the customer radio so that it can not be accessed from the LAN port if you are concerned about your customers trying to access the radio. With those two options set the only way to access the customer radio is through the wireless interface using the separate management interface IP address.

As far as GPS sync goes you can think of it as an RF shield that blocks 100% of the RF from other Access Points using the same GPS sync. GPS sync only prevents the AP's from interfering with each other though so if you have a customer radio that can see two or more APs running the same frequency as the AP it is connected to then that customer radio will interfear with those other APs and be interfered by those other APs.

So if you are doing ABAB and you have customer on one of the A's and that customer is close enough see and be seen by the other A then GPS sync will not stop that customer radio from interfering with or being interfered with the other A sector. Only the sectors front / back ratio will help you there and/or shielding.

We are in the middle of changing out all of our ubiquiti gear with ePMP and the biggest reason is GPS sync. We had reached a point with Ubiquiti where we could not deploy even one more AP without that AP interfering with one of our other Ubiquiti APs. We were completely out of spectrum. With GPS sync the AP's become invisible to each other allowing us to reuse spectrum we could not reuse before and expand.

With only two exceptions so far every single customer we have changed over from Ubiquiti to ePMP have commented on how much better their internet runs "Since you put that new satellite on" yeah they call the radios satellites and there's nothing ever going to change that I don't think.

If you are going to swap out Ubiquiti for ePMP then more great news ! With the exception of the 5Ghz connectorized customer radio all the ePMP radios will run on the existing Ubiquiti power supplies. So you don't have to wait for customers to be home before you swap you can schedule it any time and swap it out while they are at work or whateverbecause you don't need in the house/business.
