I am baffled. My local cable TV/broadband supplier was just purchased by Bresnan. When the switchover happened, my iPad was unaffected. My wife’s Windows machine seems functional except for outgoing email and some issues with streaming video. My Macs have gone wonky.
Some sites seem to work fine. Some (e.g. Facebook) won’t come up at all. Others work partially (I can view SDMB from the Macs, but can’t post). When I run a speed test using speedtest.net, the Macs show the same download speed as the Windows computer, but can’t connect to the upload speed test at all.
I spent an hour and a half on the phone with Bresnan tech support and they have no clue what’s going on. They confirmed the Mac problem with their proprietary speed test, but since the Windows machine and my iPad are working, they say I goofed up something on the Macs. I changed nothing. It worked one day (when it was Cable Montana) and didn’t work the next (when it was Bresnan).
Both Macs are running OS X 10.5.8. One is a MacBook Pro and the other is a 17" iMac.
I thought of that yesterday and tried adding two public DNS servers (8.8.8.8 and 8.8.4.4) to the list, but that didn’t change anything. Then the service tech on the phone said the three that came up from the router were correct, so that wasn’t it.
I successfully used a site (Lynda.com) for over an hour, watching free instructional videos. Then I signed up for the paid plan, logged in, and I could no longer view any page on that site. Cookies?
I tried disabling the firewall on the router. Made no difference.
I tried the Mac using two other networks. Both work fine. Came back to the Bresnan network and it doesn’t work correctly once again.
IANA Mac Guy, but if a windows machine was behaving this way I would think about stripping and reloading java and or flash and purging any browser settings/cookies/tempfiles
drachillix, I did reload Flash and purge all cache and cookies. I didn’t try Java. But remember, it’s only happening on that Bresnan connection. When I switch to the WiFi hotspot from my iPhone or take the computer in to work, everything works fine.
tellyworth, it hangs when it fails. For example, if I type this response when connected to my phone’s hotspot, I can click “Post” and it will post. If I type this when connected to Bresnan, it will just sit and spin the “loading” button. With the speed test, it does download speed normally (no problem, good speed), and then hangs trying to do the upload speed test.
The new DNS servers are the ones Bresnan tech support says to use (and they’re working on the Windows machines and on my iPad).
Times are pretty ugly pinging 8.8.8.8 (ranging from 151 ms to 3959 ms), but no packet loss.
Have you tried to ping an unresolved address (i.e. ping www.yahoo.com or something similar)? If so, what were the results? It sounds like it’s still a resolution issue to me, even though you say you have the right DNS addresses. If your ping times are really bad, and if the first tier DNS isn’t resolving properly it might be timing out on your Mac but bulling through on your Windows box.
If you are resolving properly then I’m not sure what the problem would be on the Mac but not on the Windows or iPad.
I know it’s painfully, if not obnoxiously obvious, but have you rebooted and power-cycled everything?
If your home net is like mine, yes, it’s a pain to have to run around and bounce the DSL bridge, the broadband router, the switch and the Homeplugs, and then bring up the computers and various other Ethernet-eating things, but every so often, it’s needed to blow the crud out of the lines, so to speak. At least it’s been easier once I realized that cutting the house main breaker, bouncing the UPS that powers the core network gear and then restoring house power does it all without as much legwork.
BTW: those ping times for 8.8.8.8 are wicked and the range is wacky. My average is about 27 ms.
Believe me, I know that’s not normal. And the problem is always occurring when I’m connected to Bresnan. It’s very consistent.
No such options in OSX 10.5.8
Didn’t have much choice. I did do that on my own when the problems first started, but then we had a windstorm today and power went out. I took the opportunity to shut off the UPS’s and make sure everything cycled.
I’ve never gotten 27 ms out here (them’s big-city numbers), but 40-70 is pretty normal for us. At least until Cable Montana got bought out.
I finally got a tech out to the house. It turns out that Bresnan replaced the whole back end when they took over Cable MT, but they left the old front end in place. There is a compatibility issue that’s affecting hundreds of people, me included. It’s not a problem with my systems.
It took them five freakin’ days to admit there’s an infrastructure problem!
Thats still really odd that it would only effect one platform once the router has the connection especially after manually specifying DNS, what PC is asking shouldnt matter whether its windows, mac, or an XBOX.
It affects the platforms differently, but it does affect everything – it’s just more catastrophic on the Mac than it is on the iPad or the Windows box. The tech that came to the house told me about another customer that has two computers side-by-side: one Windows 7 and one Windows XP. Last Wednesday, both worked fine. Thursday morning, after the switchover to Bresnan, the Internet connection on the Win7 machine worked, but not the one of the WinXP machine. My wife can’t send email from her Win7 machine, but I can from my Mac. It’s just strange.
The tech didn’t know how old the equipment is that they’re replacing (he called it “ancient by Internet standards”) so I don’t know if it can handle IPv6 correctly or not. Hopefully, this all goes away Thursday night when they upgrade their front-end.
