safari has lags after new router installed

Question

safari has lags after new router installed

On my G5 Power Mac running 10.5.8

I use a hawking HWDN2A USB wireless adapter

I have an Xfinity modem

I added a linksys E2500 router about 40 feet away

Prior to all he new router, the xfinity modem has its own built in (not very good) router.The router was turned off by Comcast when we installed the new router.

There are 4 different computers in this house, this Mac and 3 different HP laptops running either Vista or 7

In order to upgrade speeds, we added the new router. The result is much better speed. On my Mac, using Speedtest by OOkla, I average around 18.5 Mbps download/ 3.5 upload.

The computer running Windows 7 (Firefox browser) works fine. It's pages load quickly. I tried Firefox on this Mac, same results as Safari.

Now Safari is acting weirdly. Cached webpages load quickly, as before. However, a request for a new page can take up to 10 seconds to begin to load. It seems indiscriminate. Some sites load up immediately, some take forever. Also, in Safari's google search field, an intial search takes about 5 seconds; from the Google site, it's instantaneous. Both were instantenous with the old router.

I've followed a bunch of suggestions from these forums.

1. Changed DNS to ones recommended by namebench after I ran a number of tests using that application.

2. Changes channels on the router

3. cleared DNS cache using terminal (dscacheutil -flushcache)

4. Added a new location, using OpenDNS DNS servers (copied IP address, subnet mask, and router setting from the active location)

5. Ran applejack AUTO for a deep cleaning and permissions repair, just in case.

Nothing. No change.

There must be something I*'m missing. Any ideas?

Hi, no idea really, youve donea few things already nI woiul've suggested.

Make a New Location, Using network locations in Mac OS X ...

http://support.apple.com/kb/HT2712

10.5, 10.6, 10.7 & 10.8…

System Preferences>Network, top of window>Locations>Edit Locations, little plus icon, give it a name.

10.5.x/10.6.x/10.7.x instructions...

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

If using Wifi/Airport...

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

For 10.5/10.6/10.7/10.8, System Preferences>Network, unlock the lock if need be, highlight the Interface you use to connect to Internet, click on the advanced button, click on the DNS tab, click on the little plus icon, then add these numbers...

208.67.222.222

208.67.220.220

(There may be better or faster DNS numbers in your area, but these should be a good test).

Click OK.

Boy, I don't like the words "no idea, really" especially from you...

As noted, I did saet up a new location using both the apple HT2717 guide (which has some incorrect info: no port configuration choices in 10.5.8)

Also, I followed the above instructions you gave to Kirsten 3000 in May 2013 as much as possible. perhaps you can explain further:

System Preferences>Network, click on the little gear at the bottom next to the + & - icons, (unlock lock first if locked), choose Set Service Order.

The interface that connects to the Internet should be dragged to the top of the list.

I accomplished this, activated this new location, no change.

If using Wifi/Airport...

Instead of joining your Network from the list, click the WiFi icon at the top, and click join other network. Fill in everything as needed.

What? I'm using A USB adapter, so it slows up like so (screen grab included below)

When I set up a new location, I Configured manually and wrote in the IP address, subnet mask, router and DNS servers.

Anything else I can do?

Ah, OK, in your Wifi Utility, what does Link Status show?

And the Statistics tab, any errors or dropped frames?

That's a pretty high number of retries, 1st suspect would be Interference, have we tried a different Channel on the Router?

I have tried ch 1, 6 and 11. They are the ones linksys suggersted. Don't know why not the others. Currently on 11, no change in loading time.

1, 6, & 11 are the only "Pure" channels, usually they are best, but not always.

On the Router, click on Network Mode, what are the choices? Is there an 802.11g Only mode? Are there any 802.11b devices connecting to the Router?

awaiting your reply, I've tried ch 10, 9, without any difference in the loading speed. Do I need to restart or anything else to make the channel setting effective? I don't think so, but thought I'd check.

Network mode choices: Mixed (current), Wireless B, G only, Wireless B only, Wireless G only, Wireless N only, Disabled

also had to look up what 802.11b devices you might be talking about: we have a cordless phone near the router, and a magic mike thingamajig (not mine). Neither seemed to affect the old router. This is all new router problem.

I'd try the Wireless G only, & disable those 2 things that didn't interfere before.

I will get back to this in the next few days. Just got really busy.

I disabled the phone and it seems to be faster, but I can't leave it disabled (not my phone, can't be moved because that's where the modem is) Anything I can do to get around it's possible interference without shutting it down?

I'll try Wireless G when I can. I have a few other foilks whose wimdows machines might be affected by a Mode switch, so I need to be around in case I have to fix their settings.
