Re: [WISPA] no net but ping works
I agree... sounds like an arp issue. You don't happen to have two client bridges before this ap do you? If so you probably have customers battling each other in the arpnat tables. For instance one client starts pinging, other client stops working. Other client starts pinging, first stops working. Does this sound like the case? Have a client with the problem do a nslookup before a ping. It sounds much like a dns or a arp issue as mentioned. Can you route each Powerstation ? I like to bridge the AP (with dedicated ports behind them) and WDS the clients (with their radios running internal routed 10.x subnets , no nat!). This has show to be the best balance between speed and stability. Also check the powerstation arp tables as well as the upstream router, before they issue the nslookup or ping, then after. Also try disabling dns caching on the client radios.

Re: [WISPA] no net but ping works
Had a similar problem when testing UBNT's. Seems they broadcast CDP's that fill up Linksys router arp caches. Rebooting the routers made problem go away, but only temp. Took the UBNT stuff off the network and all was well. Also Brother printers can cause the same issue. Try blocking interclient traffic on the AP's: that helps as well.

Re: [WISPA] no net but ping works
Hi Greg, I think I understand what you are asking for... since this type of stuff tends to me more of an exercise heavily influenced by personal preference or judgment...Having said that, let me share with you some starting config... I am sure other can chime in with more suggestions. -- We are using a small Mikrotik in each of our Wireless POP's, at the moment we are using 750g and or 493ah Each Radio (Ap / Backhaul etc) is connected to each individual port on the MK. Non of the ports are grouped into a switch group...i.e. each port is a'routed port'. Each port has multiple subnets (block of IP's). I am starting off with /27's assigned to each port. A private block of /27 on each port, that we are using for radio management. An initial public block of /27 on each port ( connected to AP's) for end customer usage. We are not doing NAT on the MK, assigning public ip to each customer. or assigning a small routed block /29 for customer. (Mostly business customers) On the Up-Stream / Down-Stream Backhaul... we are using a /29, public for routing and private for Radio management In this type of config, you can run all Static Routing or turn on OSPF or whatever makes you happy (dynamic routing). We create an IPSEC tunnel between the MK and our NOC's Firewall, thus allowing direct access to the Private IP's (Our MGMT network is on the private IP's. Plus, we also leave a PPTP config on the MK, incase one needs to access the Mgmt side of the radios they can connect to that MK and access the mgmt network. There are a lot of other little small details about configuration / security etc, most of them to suite your needs / standards taste. We run each of the AP's with it's own SSID, in Straight Bridge Mode, so the CPE's are bridged to AP, or if need be, the CPE can also be in a Routed Mode to route a public subnet across it. Hope this gives you some ideas on where to start from.

Re: [WISPA] no net but ping works
I doubt it's DNS but you can test that. When they cannot connect via URL have them try to access the site via IP. If they can access it it's DNS, if they can't it's ARP. If it's not DNS, the next step is to log into your router when the customer cannot connect and see if there is an ARP entry. I'm betting it's timing out out an not refreshing until you ping the gateway from the CPE (Ping is ARPless). Finding where/why the ARP request is dying is the tryicky part. With the customer still unable to connect, log into the AP and ping the CPE and then have the customer try to load the page. If that works the issue is probably between the AP and CPE. If not, move to the next device up the chain each time pinging the CPE until the customer can connect. As a temporary measure you could add a static ARP entry in the router but that's a bandaid and may mask a more serious problem. - Jerry -Original Message- From: wireless-boun...@wispa.org [mailto:wireless-boun...@wispa.org] On Behalf Of Mark Dueck Sent: Thursday, August 26, 2010 8:15 AM To: wireless@wispa.org Subject: Re: [WISPA] no net but ping works I have about 25 clients on this AP.

Re: [WISPA] no net but ping works
I went to a client again, and did some nslookups. here's what I found: All radios are setup as dns relay. When I got to the client, he had no internet. I first did a nslookup to google.com, and the radio responded with unknown. I changed radio to dns relay off and added 8.8.8.8 as a secondary dns. I still got no response. When I then pinged 8.8.8.8, there was no response either, but pinging the gateway, I got immediate response. The pinging 8.8.8.8 and internet all started working.. This was an SL2 with the RTS at 3000.. I'm also getting this report from other clients that are not connected to that AP, so I don't think it's an RTS issue. Any other ideas?

Re: [WISPA] no net but ping works
An RTS/CTS setting of 3000 means it's effectively disabled. You'd have to set it below 1500 for it to do anything. It's not looking like that's your problem anyway. RTS/CTS will help performance when customers upload large frames (specifically ones larger than your RTS/CTS setting). You'd have to set it to 100 for it to affect DNS/ARP/ICMP packets, and that would likely be a really really bad idea. My money is on too many layers of MAC NAT. Tranzeo and UBNT stations do it regardless, and MikroTik's do it with station-pseudobridge set. Do you know how many MAC NAT'd stations you have changed together? If there are multiple hops, switching intermediate ones to WDS should help/resolve the problem. -Kristian On Thu, 2010-08-26 at 09:15 -0600, Mark Dueck wrote: I have about 25 clients on this AP.

Re: [WISPA] no net but ping works
I have about 25 clients on this AP. I think only 2 of them are NS2's, the rest are SL2's and they are all updated to 5.0.4 firmware, which has the fix for the limited connections that the 4.x firmware had. All the Tranzeo's have their RTS at 3000, their default. I checked the NS2's, but I can't find that setting in the webGUI. How do I check/change that?

Re: [WISPA] no net but ping works
You have to set it to 512 for DNS. Remember that DNS is UDP so if the packets go away because the wireless medium you are using is lossy then there are no more re-transmits. Setting the RTS/CTS to just at the size of a UDP DNS packet creates a virtual TCP-like network for those sized packets. ryan On Thu, Aug 26, 2010 at 9:42 AM, Kristian Hoffmann kh...@fire2wire.com wrote: An RTS/CTS setting of 3000 means it's effectively disabled. You'd have to set it below 1500 for it to do anything. It's not looking like that's your problem anyway. RTS/CTS will help performance when customers upload large frames (specifically ones larger than your RTS/CTS setting). You'd have to set it to 100 for it to affect DNS/ARP/ICMP packets, and that would likely be a really really bad idea. My money is on too many layers of MAC NAT. Tranzeo and UBNT stations do it regardless, and MikroTik's do it with station-pseudobridge set. Do you know how many MAC NAT'd stations you have changed together? If there are multiple hops, switching intermediate ones to WDS should help/resolve the problem. -Kristian On Thu, 2010-08-26 at 09:15 -0600, Mark Dueck wrote: I have about 25 clients on this AP.

Re: [WISPA] no net but ping works
Customer can get to CPE all the time. This customer had the CPE plugged into switch, then from switch to laptop. I was able to ping AP all the time, and I'm running nagios for monitoring, and I never see any issues. Network seeps to be quite stable, and whenever I ping any clients, even if I ping every .2 seconds, I don't see any problems either. Client can call and say they have no net, and when I ping them it makes no difference. I guess its quite clear now it's an ARP issue. How do I fix that? Most of my links are PtP. APs are all bridged. POPs are mostly bridged too, and the one POP that routed is not having any problems. I'm running ClearOS for my gateway. It has very nice multiwan and I'm using it at the same time for DNS caching. All clients use it for DNS. At what point should I consider putting up a dedicated DNS server? currently have about 60 clients. On 08/26/2010 10:46 AM, Josh Luthman wrote: What is the PC's gateway?

Re: [WISPA] no net but ping works
I just tcpdump'd a DNS request for google.com. The request (the one that would be affected by RTS/CTS) was 32 bytes. The reply was 220 bytes. So I maintain that you'd have to have the RTS/CTS threshold less than 32 + IP header size. If a wireless network is having contention problems with 50 byte packets, RTS/CTS isn't going to help. But I think we've wandered OT. -Kristian On Thu, 2010-08-26 at 10:07 -0700, Ryan Spott wrote: You have to set it to 512 for DNS. Remember that DNS is UDP so if the packets go away because the wireless medium you are using is lossy then there are no more re-transmits. Setting the RTS/CTS to just at the size of a UDP DNS packet creates a virtual TCP-like network for those sized packets. ryan On Thu, Aug 26, 2010 at 9:42 AM, Kristian Hoffmann kh...@fire2wire.com wrote: An RTS/CTS setting of 3000 means it's effectively disabled. You'd have to set it below 1500 for it to do anything. It's not looking like that's your problem anyway. RTS/CTS will help performance when customers upload large frames (specifically ones larger than your RTS/CTS setting). You'd have to set it to 100 for it to affect DNS/ARP/ICMP packets, and that would likely be a really really bad idea. My money is on too many layers of MAC NAT. Tranzeo and UBNT stations do it regardless, and MikroTik's do it with station-pseudobridge set. Do you know how many MAC NAT'd stations you have changed together? If there are multiple hops, switching intermediate ones to WDS should help/resolve the problem. -Kristian On Thu, 2010-08-26 at 09:15 -0600, Mark Dueck wrote: I have about 25 clients on this AP.

Re: [WISPA] no net but ping works
Ping is ARPless. But when you hit the interface of the router with a ping an ARP entry is made and is good until it tiles out. For whatever reason ARP requests are not getting through. Either a Linux box or a Win app than can send an ARP ping would be very useful.

Re: [WISPA] no net but ping works
Every time an IP packet is sent over an ethernet interface, the destination MAC address needs to be resolved to either the MAC address of the gateway or the destination IP on the same subnet. If an existing (non-stale) ARP entry is in the ARP table, it will use the MAC address from the cache. Otherwise the IP stack triggers an ARP request to resolve the MAC address. So you're both right. ICMP, TCP, UDP, etc. don't use ARP, your IP stack does. But you couldn't send any IP packets without ARP. Your picture just shows that there wasn't a non-stale ARP entry in the cache, so it triggered an ARP request before it was able to send the ICMP packet.

Re: [WISPA] no net but ping works
My point being with ARP you can't ping. Regardless if the ARP happens right after you issue the ping command or it learned the MAC from ARP hours ago, you still need ARP to do ping.

Re: [WISPA] no net but ping works
This problem seems similar to the issue we had recently. We originally had all of our (bridged) radios on a 10.0.x.x network with a Class B Subnet (255.255.0.0) - Started seeing real weird issues with the new gear we were deploying - Tranzeo / UBNT had same problems. Clients would just drop off for a while. Changed that particular link to a Class C (255.255.255.0) and the problems stopped. Still bridged / Still on a 10.0.x.x IP Scheme. Something odd in the bridge tables, or arp tables in those radios.

[WISPA] Seeking 4.9Ghz Advice
Hey guys, We may be getting into some 4.9Ghz deployments soon and I thought I would check with you guys to see what sort of tips and 'gotchas' you may know of if you currently are operating in 4.9. We are having a meeting soon with the local municipality to see how we can work together to get this potentially going for the benefit of everyone in the community. Please feel free to email me directly if you'd prefer with any advice or tips in working with the local government, what equipment you recommend, maybe legal advice, etc. I know that's vague, but I hope it's specific enough as well :) .. thanks. -Steven WISPA Wants You!

Re: [WISPA] Plastic jacket is the major cause of ESD damage...
Mike ford is describing electrostatic charge buildup on the outside of the cable jacket. This occurs because the friction between air molecules moving by and the surface of the cable jacket causes a charge separation on the surface of the jacket. In conductive materials this charge would simply bleed off, but a good plastic cable insulator will retain the charge on the surface of the jacket until the voltage is so high that it exceeds the breakdown voltage of the jacket. Then the charge dissipates through the nearest path to ground, which could be through a sensitive electronic component in the radio. Shielded cables and connectors will solve this problem by dumping the charge to ground once it builds up enough to jump through the cable jacket. This is different than the usual EMI scenarios we look at as WISPs--namely induced currents in ethernet cables due to strong nearby electric fields.

Re: [WISPA] Seeking 4.9Ghz Advice
So are you going to be doing some municipal video surveillance or something for the Fire or Police department? The 4.9 band is PUBLIC SAFETY only. I have deployed a lot of it in my area on surveillance projects for the PD and some at the University of Georgia (for their PD). It all has to be licensed and as was said by someone else before it CANNOT be used for regular ISP stuff. That said, I was not impressed with the performance. There seemed to be a lot of interference and I ended up only using 4 links and they were all about 2 blocks in length. There's not a lot of certified equipment out there (don't even THINK about Mikrotik) and what is there is expensive.

We've done most of the city of Mansfield, Ohio using Firetide Mesh radios. Rock Solid system. You're welcome to contact me about what we're doing with it. As far as pricing - My experience has been, if you offer it too cheap to a municipality (Government people..) they assume it's not good, and won't even consider you. I've seen some of the idiots in my city pay $125 an hour for a Consultant to tell them the same thing that I said for free...

Re: [WISPA] Plastic jacket is the major cause of ESD damage...
Mr. Shoemaker, So the effect you are describing below is the result of wind rather than induced energy from a nearby lightning strike? When I was a maritime radio officer I witnessed very strong static electricity on non-dc grounded antennas during storms. I've seen repeated rapid static discharges across PL-259 connectors that went on for minutes as a rain squall blew past. I assume you're talking about this effect. If plain old non-shielded ethernet cable is wired tied to antenna support, down the tower and to cable tray at the bottom of the tower doesn't that give the static charge on the outside of the jacket a place to go?
