Draft N odyssey

A while ago, four month to be exact, I had the fine idea to upgrade my network. I wanted to switch my WiFi to Draft N and my LAN should be 1000 MBps. That was the plan. My old setup was a Netgear FVS338 in combination with two Linksys WRT-54G. This was a dream setup and actually no good reason to upgrade, despite the WiFi bandwidth was at its limits. I sync music and videos via wireless LAN connection and a copy progress that lasts for like 10 hours is not acceptable.

On last year’s Black Friday I bought two Buffalo WHR-HP-G300N. I wanted to replace all my devices I had in use with these two. One should work as router, switch and access point. Tasks that were shared by the Netgear router and the Linksys access point. So far so good, this setup worked. The second Buffalo router should work as a client bridge. Bummer!

It’s almost impossible to get this router into a working or at least stable client bridge mode. Sometimes the router wasn’t able to connect to the current WiFi. Sometimes I had a WiFi connection but no access to anything else. After a long time of research, I finally found one firmware version that offered a stable client bridge mode. But after all I’ve experienced, it seem to depend on the weather and the current moon phase. In good times I was able to have stable connections for days and in bad times it crashed after almost five minutes. I replaced this stupid devices with my old Linksys access point and everything was fine.

Another problem left, I couldn’t get a stable connection for my HTC smart phone. I connected, had WAN access for like 10 minutes and then it dropped for good. I had to reboot the phone to get back on the track. I replaced the Buffalo router with a TP-Link TL-WR1043ND. It was a good device, though. But finally, it was based on WRT firmware and had the same Draft N issues like the Buffalo router. Retoure.

Last but not least, I got back to the roots and bought a D-Link router. D-Link has been a good companion in the good old days, when I had my first broadband connection and it was one of the most stable devices I can remember, beside the Netgear FVS338, which is an absolute killer device.

So, I got this D-Link DIR-655 and set up my net again and after a long period of pure despair, WiFi was running perfectly fine. For one reason did my broadband modem start to play some tricks on me by crashing and reconnecting randomly. I was near to return the D-Link router, but I gladly noticed those weird blinking LEDs on my modem. Culprit found.

I’m still trying to get the Buffalo working in client bridge mode when I find the time to set this stupid thing up and can do some research on this particular problem, but no real solution so far. The devices uses to crash whenever possible.

Never change a running system

I’ve been thinking about redesigning my home’s network infrastructure for a while now and Cyber Monday gave me a nice opportunity to grab some cheap WiFi devices. It was time to replace my obviously oversized Netgear VPN router in combination with a Linksys WAP54G access point. To have everything combined in one device, that was the goal. And this goal was reached – almost.

Two Buffalo WHR-HP-G300-NG routers were the deal I took on and they arrived pretty soon. I’m very, VERY familiar with WRT routers, or let us say DD-WRT itself, but these two Buffalos cost me nerves, if you know what I mean.

I use one router as a router (sure thing) and also as an access point (makes sense). The second router is getting used as an access point in client bridge mode to connect my media centre with the rest of my network. I unboxed the devices, switched them on, ignored the standard firmware and instantly flashed the recommended DD-WRT firmware.

This is where the real struggle began. First router worked perfectly fine so far. WiFi signals was kind of awesome and connection speed itself also improved. I configured the second router and nothing was happening. Client bridge mode was not working.

I checked my settings and everything seemed okay, actually, everything was already alright. While researching and debugging I got a connection out of nowhere. I was happy and almost ready to get some sleep. Well, I had a connection for like five minutes and everything broke down again.

A week of research followed. I’ve found one workaround, which was to run my client bridge router in client mode only. That helped to get rid of the fitful disconnects. I also found one DD-WRT firmware version that was able to keep the connection even in client bridge mode but disconnection followed after almost an hour and the router completely crashed.

Meanwhile, I replaced the second router with my old Linksys access point that handles the client bridge mode perfectly well. Connection on my media centre is fine and my buffering problem is also solved. So here comes the second issue.

One of my smart phones  has got a problem with the WiFi. It is connected, but it is not able to connect to the Internet. Strange, totally strange weird too. Well, my client bridge problem is not solved actually and I’ve got a smart phone that can no longer connect to the Internet. Leads me to the conclusion, never change a running system.
