Re: [WIRELESS-LAN] MERU wireless
We have a deployment of over 1500 Meru access point connected to a mixture of 16 3000 and 4100 controllers. Over the years we have had numerous problems. Code upgrades may fix the immediate problem, but then cause a new batch of issues. For example, the last upgrade we went from 4.0-105 to 4.0-131 it fixed problems with our captive portal, 802.1x authentication problems, and SNMP issues. However, shortly after this upgrade our users could no longer connect for more then 5 to 10 minutes. After which they would either get disconnected from the AP or network traffic would stop flowing. Other issues we have had are access point reboot at random, clients (mainly Apple/OSX) can not authentication to 802.1x SSIDs, DHCP stops working (DHCP replies do not make it back to the clients), access point stop responding to clients. They look fine from the controllers, but clients can not associate with them. Management of the entire system is a bit clunky. The web interface locks up all the time. It either requires the controller to be rebooted or the management interface to be reloaded. To configure high dense areas lots manual configuration is required. This makes it very difficult to manage on a large number of controllers with high dense areas. Our performance testing on the 2xx series access points is no where near what Meru claims they can do. For example, we can get about 7 people streaming a local video content before performance is so bad for all the clients that the video stops working all together. Support, although it has been getting better, can be very difficult. The frontline support has struggled, but once you reach an engineer they seem very helpful. So a couple questions for those of you that have had good success with Meru: - What version of code are you running - What style of AP's do you use - Do you use different style access points within the same air space - Do you have problems in high dense areas without using the N radio - What style of controllers Chris Huels Network Engineer Washington University in St. Louis cjhu...@wustl.edu 314-935-4241 On 4/18/11 10:40 AM, Jason Hall ha...@denison.edu wrote: I have Meru running along side Cisco and 5G access points without any issues.

RE: [WIRELESS-LAN] MERU wireless
Meru: - What version of code are you running Just upgraded to 4.0-150. So far it seems fine. It resolved the administration interface lock ups we were seeing. - What style of AP's do you use We have mix of 208's and 311's. - Do you use different style access points within the same air space No. Meru doesn't recommend this. We keep an entire building as one AP type and our 208's and 311's are in separate ESS profiles as per Meru's recommendations. Yes, it makes our refresh cycle longer. - Do you have problems in high dense areas without using the N radio We have 208's in our Law School Auditoriums. We had to install additional AP's to handle capacity, but since then no major complaints. We do receive complaints from our Medical School about one large auditorium with 208's when they try to use high bandwidth applications. Once we get more information on their application usage, we plan to augment coverage with additional AP's and channel layering. - What style of controllers We started with 3000's and upgraded to 5000's. We also have three 4100's. We still do see random AP reboot's and we have run across the slient AP issue others have been seeing. We have been testing the Service Assurance Manager in our dorms and it has been helpful indentifying some of the silent AP issues. ** Participation and subscription information for this EDUCAUSE Constituent Group discussion list can be found at http://www.educause.edu/groups/.
Re: [WIRELESS-LAN] MERU wireless
Thanks for all the great feedback, it is appreciated. I have another question regarding coexisting. Did anyone have Meru and Cisco running at the same time and what issues did you see. Obviously with our current state of funding we can't fork-lift replace our entire Cisco wireless system so they would need to coexist for the duration of funding the replacements.

Re: [WIRELESS-LAN] MERU wireless
Hi Randy, We're long time customers of Meru, have been please with the product support. We have a mix of AP208s (a/g) AP320 (a/g/n), over 1100 altogether. We also use their EzRF product for managing the controllers. We like the single channel architecture, which works well for us. In higher density locations, we stack channels to provide more bandwidth per user. We plan to first support IPv6 on our wireless infrastructure because of the number of devices we're seeing now what we project in the future. Most of the problems we've had with the product were due to client chipset issues, or controller software bugs that have been addressed over time. When we've reported issues to them, they've been very good at getting back to us with solutions. We'd be happy to talk with you on/off line about our experience.

Re: [WIRELESS-LAN] MERU wireless
A couple years ago we tested Meru, Aruba and Cisco wireless out in one of our buildings to see which system would best fit our environment. During the Meru test we had a serious failure caused by a bug in the code. Later I found out there was a work around, but as a result of that I had the pleasure of having the worst support experience I've ever had. It may have just been poor luck but that was enough to take them out of the running for me. I was assured by the sales team that if we went with Meru we would have immediate access to their US based support with immediate escalation but I've seen too many sales promises fall by the wayside once the purchase has gone through.

RE: [WIRELESS-LAN] MERU wireless
Meru currently supports IPv6 in bridging only mode, so you lose some of Meru's proprietary traffic management features. In testing I've had issues with SLAAC, but Illinois has not, so your mileage may vary. I haven't tested it since version 3.6 of their code. Our campus is currently routing IPv6 everywhere and plans are under way to IPv6 enable more services (we plan to participate in World IPv6 Day by enabling records for our Microsoft servers), so I'm getting asked every week when IPv6 will be supported on wireless. Meru understands that IPv6 support is a priority and they do have a roadmap for IPv6 support, but I think I'm under a NDA about that. -Neil -- Neil Johnson Network Engineer Information Technology Services The University of Iowa 319 384-0938 neil-john...@uiowa.edu -Original Message- From: The EDUCAUSE Wireless Issues Constituent Group Listserv [mailto:WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU] On Behalf Of Frank Bulk Sent: Wednesday, April 13, 2011 11:08 AM To: WIRELESS-LAN@LISTSERV.EDUCAUSE.EDU Subject: Re: [WIRELESS-LAN] MERU wireless I was told by our local college last year already that Meru doesn't support IPv6 -- is that still the case?

[WIRELESS-LAN] Meru Wireless AP's Intel Wireless Cards
I'm late to the discussion, but wanted to throw in my two cents. We recently deployed Meru in one dormitory with version 3.1.4-33. We had multiple complaints of low or spotty connectivity. In most cases, a driver update resolved the issue. In one case, we could not get the Intel card to work at all, and issued the student a USB b/g card with its own management, and that took care of the issue. We recently upgraded to 3.2.5-71. Since the upgrade (which was tortuous - Meru says they are still working out bugs in the upgrade process and I highly recommend not upgrading until they are worked out) we have not heard any complaints, but I'm not sure if we just took care of them all prior to the upgrade, or if the upgrade itself resolved the issue. We'll keep you posted!

These users were using the latest Intel Pro wireless cards on their laptops. The fix that Meru support suggested of disabling the power save mode on the cards does not work 100% of the time. Upgrading the latest firmware/drivers for the wireless cards do not work 100% all the time as well. Plus, certain Mac's are having same problems. With Mac's, we've noticed that an older firmware has no issues, where a laptop with the latest is experiencing the disconnect problems. We saw similar issues, but thought that the workaround provided by Meru had been working. I just was told yesterday that no, a number of people are still having problems. I don't have any good answers for you, since we're just starting to ask some of these questions. Basically a laptop can connect, it says it's connected with a good signal, but can't get online. If one can get online, the connection is lost in about a minute or so. There are two things that we've noticed when this had started. 1. The Meru software was upgraded to the latest version recently 2. The Meru switches are almost maxed on the # of AP's allowed per.

Aruba vs. Meru wireless
Hi All, I apologize if this is a repeat of an earlier question. We are looking toinstall a wireless network in our library. We have limited funds (just like everybody else) but would like to do this the right way. We have been given a certain amount of funds to get this in place by the end of the year. We have had a few vendors out and have narrowed it down to two vendors that we like.We plan toexpand the wireless network to other areas on campus, both interior and exterior access points,when further funding becomes available. It is very important that we buy a solid infrastructure at this point that will scale right from the beginning. Has anyone done any comparisons of Meru vs. Aruba? Future price is also something we need to consider as we expand the wireless network. Thanks for all your help.
